Everything I needed - plus things I didn't

Written By Matthew, Muncie, IN on Tuesday, August 04, 2015

Crutchfield Customer Review (What's this?)

The CR2-FRD1 has everything I needed for the install in my 2009 Ford F-150 - My vehicle has the base model audio system, which was a major factor in the purchase of vehicle. The only issue I have is the amount of leftover wiring in the unit. PAC would have my undying admiration if only they could engineer an interface to transfer the aftermarket head unit's display to the factory display, as you lose the clock & tuner/track info

Pros: well engineered, easy to install

Cons: leftover items in harness my vehicle doesn't require

Great Interface

Written By sc517hp, Lees Summit, MO on Tuesday, June 23, 2015

Crutchfield Customer Review (What's this?)

If you plan on using your stock harness this is the only way to go. The hardest part is connecting all the individual wires to the deck pigtail. I soldered and shrink-wrapped mine so it took a while, but if you use crimp connectors or wire nuts it would take about 5 min to have it ready to plug in. This one had the bug fix diode already installed from the factory.

Pros: simplifies installation with stock harness

Cons: instructions could be more clear

Written By PAC C2R-FRD1 Wiring Interface for 07 Expedition, South Carolina on Monday, March 16, 2015

Crutchfield Customer Review (What's this?)

Everyhting was as discribed in the post. However, reason for 4 stars is i still had to go wire by wire and tie these to the Sterio. I was under the impression it would be Plug and Play. Basically were paying for the interface so that the Clarion unit functions with the car (Reverse, Sound controls, etc). I was looking for that and plug and play. 4 wires were not color for color so luckily i contacted Crutchfield service to ask why i had a long green wire and a purple wire that didnt have the same thing on the Sterio. I i had just wired it up there would have been issues for sure. Better Work Instructions would also be handy

Pros: Seemless intergration with my Factory controls

Cons: Still required wire to wire connection, 4 wires didnt match color to color, (Could have been a disaster), Not plug and play, (I would have paid $50 for this feature)

A lot of extra wires for my install. For the money it should of had all the xtras like steering wheel controls back up camera and so on. It made the install easy . Some of the wires could of been labeled better as some weren't labeled at all

Pros: Definitely beats cutting factory harness.

Cons: Needed better labeling . Price was way high . Could of probably bought cheaper had I know what harness was needed. Needs lil better directions to take guess work out of extra wires

This is one of those things you need if you want an after market stereo. Just take your time, I laid it out on paper before I did anything. This way I could figure out where everything went.

Pros: Got the radio working.

Cons: Lots of unused wires. Need more explanation with the instruction. We're not all professional installers.

This product works great I have a 2006 Ford Five hundred with the premium sound system (six speakers) and it works wonderfully. Basic wire setup of the new stereo harness to this harness with some solider and heat shrink then its just plug and play. I also used with it the PAC SWI-RC connecting that was just the red and black then the white wire (solid white not the red or black white) and it was done. Everything works and everything sounds great.

Pros: Great instructions and easy install.

Cons: none

Used to install Blaupunkt NJ 220 in Mercury Milan with 8 speaker system. Works fine.

Pros: Has separate RCA cables for vehicle sub-woofers that connect to NJ 220 dedicated output.

Cons: One size fits all leaves many unused wires and cables that need the ends taped to avoid shorts. Really be great if the adapter came with pre-wired receiver specific connectors to avoid the rainbow tangle of manual splices.

IT worked really well, could have had a bit better wiring diagram, small writing for my old eyes. Also had minor issue with the sub interface for my Shelby GT500 Shaker1000. But a quick call to Crutchfield and the techs got me to the correct wire issue, fixed it and then had a ground interface problem, Crutchfield again sent me (at their cost) the ground loop wiring that I need to correct my problem. Working great now.... Thanks Crutchfield, will use you everytime



Written By Chase, Herrin, IL on Monday, August 04, 2014

Crutchfield Customer Review (What's this?)

This was required for my 10' Ford Focus. My vehicle did not come with sync nor a factory sub so the only feature I would be using was the 12V output. Since that was the only thing I was using there were a lot of extra cables and wires that got kind of confusing. It almost made me feel like I was not doing something right because there were so much extra stuff. I think there should be different harnesses for the different vehicles that do not have those features such as me. It would be simpler plus it would save money. Something else, the screen factory stereo screen says DVD now......... That is after I installed my stereo with this harness. That is kind of annoying considering my car has no DVD system at all? It could have at least said "Ford Focus" or something that it is already programmed to do.

Pros: Worked!

Cons: Extra wiring in my situation, screen says "DVD", kind of confusing

Crutchfield Customer Review (What's this?)

My brother installs radios and sound systems for family and friend quite often without any complications and the directions were so unclear that we had to call Crutchfield for support. There were a few wires that we found did not go to anything in my 2005 Freestyle.

My JVC now works beautifully. I just hope to not have to switch radios anytime soon.

Pros: Allows my new stereo to work very nicely and had the needed wires for the extra interface for my Steering wheel controls to connect to.

Cons: Unclear instructions. Lack of wire diagrams.

Easy to use. Almost full integration

Pros: Super simple to connect. Match color to color and plug it in.

Cons: Ford f150 2011 displays "DVD" constantly once you remove the factory radio. Not sure if it's a flaw in the harness or a result of after-market integration, but its a little annoying. Everything works fantastic as long as you don't mind the oem display not changing to the input you're actually on.

Written By DAP39, Norwalk, CT on Friday, March 22, 2013

Crutchfield Customer Review (What's this?)

Used this item in a 2008 Ford Mustang with Shaker 500 system installing a Pioneer Avic X940BT. Install was a breeze and the 5 amp diode which is needed for this application is now already installed by PAC in the wiring harness so there is no need to got to a bix box store anymore to do it yourself. Be warned that the illumination wire from a Pioneer unit to the illumination wire on the PAC harness WILL NOT WORK, the display will flash alternately between day and night mode when headlights are turned on. Ultimately after calling tech support at Pioneer, PAC and Crutchfield you will probably be offered a new module but take heed and don't waste your time with that because it is not the module. The ONLY FIX for the dimming problem is to run a wire from the illumination on the unit to your headlight switch, dimming function will then work fine! ( On the 2005-2009 Mustang with Shaker 500/100 it is the Tan/White wire on Headlight Switch).

Pros: Works Great, easy install

Cons: Dimmer function wire will not work with PAC module in certain applications, you must run wire from Head Unit to headlight switch.

Need Clear Instructions

Written By Anonymous, CT on Tuesday, January 29, 2013

Crutchfield Customer Review (What's this?)

The adapter harness works great after the install. Clear directions are lacking, You know when you bought something from Ikea and you have parts left. Your thinking to your self hmmm is this really needed??? Well I had wires and adapters left, and did not know if I needed them or not for my install. I would of hated finding out after the fact, I needed them after I put everything back togther or worse It's not working correctly and can't figure out why. I found it difficult to clearly understand what adapters and wires I did not need without calling for help. A clearly marked wiring, adapter & type install guide would have been great.

Pros: Once wired, worked like a charm. With the harness you can tie off and organize wires before the install. Putting back original radio will be easy.

Cons: Harness wiring & adapter guide is vague... Would have been great, to have the kit clearlly mark what each adapter is used for in each type of install. [Just 4 speakers that came with the car, 1 with more more speakers or steering wheel controls]. A master install sheet showing the types of installs & wires guides that go with each type of install would be helpful

Made everything so easy. Just had to solder nearly 15 wires together and then it's all plug and play!

Pros: Easy installation, easy directions (for the most part)

Cons: It was unclear what to do with the AUX and RSE RCA cables. Directions need to be a bit clearer on that. And a few of the wires too. Otherwise I'd give it 5*

Pros: Makes replacing radio easier.

Cons: Instruction are sort of hard to follow. Had instructions from head unit, PAC and steering wheel control. Instructions were not the same. Had to get help from tech support. After several call all worked perfectly.

Nice product

Written By DP, WI on Friday, July 20, 2012

Crutchfield Customer Review (What's this?)

This is a nice product, but does require some work to install. After soldering and heat shrinking all the splices into the head unit hardness, I figured the rest of the wiring would be a piece of cake. Well, as others have mentioned, the install instructions are very lacking and when it came time to hook the OEM door subs I had to call for help. We were able to figure it out, but I surprised by the lack of their lack of knowledge as I would have assumed this had been installed before into this application. I also ran into an issue after everything was installed with the head unit backlight illumination flickering on/off whenever the car lights were turned on. After a call to tech support, they were unsure if it would work through the PACs box, so they another one to test. Although they send me another one the following Monday, my car sat tore apart for 5 days while waited its arrival... only to find the exact same problem with the new PACs box. There is another option that includes hardwiring the illumination line to the headlight switch/line. Once again, I can't believe this was not known

Pros: Simplifies the install

Cons: Install instructions were terrible and incomplete

2005 Mustang - Shaker 500 replacement

Written By PJB, Munford, TN on Thursday, March 22, 2012

Crutchfield Customer Review (What's this?)

I would like to see PAC fix the issue with the feedback on amplified factory subs. While soldering a diode into the harness was no big deal it WAS one more thing to do. Without a rear seat entertainment the RCA filter was not needed either. With that being said, after taking the time to solder all of the connections (and the diode), installation was an absolute breeze and everything WORKED! A MUST HAVE if you want to retain factory features and still be able to control the outputs to the factory subs of a shaker 500/1000 system

Pros: Plug it in and GO! Retains factory features.

Cons: Required slight modification Some parts were not needed

A must for Mustang Shaker stereo system

Written By Sancho63b, APO K-Town, Germany on Friday, March 16, 2012

Crutchfield Customer Review (What's this?)

I think that this is an awesome product but I don't think it should be my responsibility to modify it in order for it to work properly. Yeah, it's a cheap fix installing a diode in between two wires but still. If the company knows about this issue already why are they not fixing it during production? Makes no sense to me.

Pros: Provides you with everything you need and don't

Cons: Doesn't really tell you how to install it.

An absolute must for the Shaker 500 / 1000

Written By Pat F., Tumwater, WA on Wednesday, February 29, 2012

Crutchfield Customer Review (What's this?)

I gave this a 4 stars because of the ease with which this unit allowed me to integrate new head unit (Sony XNV-770BT) into my 05 Mustang w/ the Shaker 1000 system. That said, when I opened the box, the internals in the actual interface unit (the larger of the two "boxes" in the photo) came out of the housing. It was necessary to clean the dried adhesive out of the housing, which just flaked off, and super glue the internals into the unit. Once this was done it worked flawlessly. I had already read about the need for the diode, so I had it on hand (less than a buck at Radio Shack) and soldered it into the appropriate wire. I soldered the harness into the Sony harness and it worked as advertised.

Pros: Seamless integration into factory system. Made install a breeze.

Cons: PAC needs better quality control and should supply the diode in the kit, with the necessary instructions.

Great but More Information Should Be Included

Written By Anonymous, West TN on Wednesday, February 08, 2012

Crutchfield Customer Review (What's this?)

A must for installing a head unit. However, additional information should be included with the kit. There is a TSP bulletin that is on PAC's website, but not included with the packaging. You have to solder a 1 amp diode on one of the wires in order for it to work properly. Very easy to do, but at this point, shouldn't it have already been fixed by the company?

Pros: Easy to install head unit

Cons: Additional work needed but not included in instructions.

Universal fit means unused parts you pay for.

Written By Chris B., Bethlehem, PA on Tuesday, February 07, 2012

Crutchfield Customer Review (What's this?)

Many people I know with the factory Shaker 500 system in the Mustang have used the $15 stereo harness adapters from the auto parts stores for aftermarket stereo installs with success and had no issues. They kept their factory subwoofer amps. However this adapter allows you to adjust your subwoofers independently and also makes the install easy. I'm amazed at the price for this adapter since some of the parts aren't used for my application and in reality the cost to manufacture this is probably not much more than the basic stereo wiring harness adapter for Ford vehicles. They need to make a kit that isn't universal and instead has just the parts needed for your application. I didn't use the RCA connectors or the box with RCA connectors in it. Those are for other vehicles.

Pros: Allows you to adjust your factory subwoofers separately from the other channels.

Cons: Expensive for just being a little circuit board in a black box. PAC still hasn't updates the unit with the diode needed for some factory stereo systems, so you have to add that part yourself after buying it at an electronics component supply store.

A Must

Written By Old Ed, LA on Wednesday, January 25, 2012

Crutchfield Customer Review (What's this?)

Although this kit contained some components I didn't require, it is a must to avoid headaches. This was the second HU I have installed and this kit was much more complex than the previous. A quick call to Crutchfield support answered my two concerns taking the complexity out of the preparation.

Pros: This product along with Crutchfield support is well worth the money.

Cons: This is a "fitzall" kit making it confusing for the novice. Don't let any extra parts bother you.

Wiring harness works but has problem with shaker 500 on mustangs

Written By big mike, Cali on Friday, June 17, 2011

Crutchfield Customer Review (What's this?)

this harness is easy to install. Has one big problem with shaker 500 system on 2006 ford mustang. On high volume the volt gets backfeeded to the receiver and causes it to repeatedly shut off. Solution is to install a diode on the wire that turns on the amp. The green and white wire. After that it should work ok

PAC C2R-FRD1 Wiring Interface

Crutchfield Customer Review (What's this?)

This product doesnt work with a 2006 Mustang GT. It cost me this much and had to be modified. I consulted Crutchfield and an additional harness was shipped with the same result. I am using all stock equipment with the exception of the aftermarket head unit. Clarion CX501. With the subwoofers connected and volume level up, It will cause the head unit to shut off and return only when the volume is decreased. I had to add a diode to the amp on wire to cure this problem. Shouldn't this diode not be in the harness?? Disatisfied with the cost and not working properly. I have also heard of this problem from others with the same set up as I.

Great harness, it works well! Only ran into the problem where I had trouble unplugging one of the connectors. Not a big deal.

Can be a bit intimidating if first time installing a stereo yourself, but it is a real
necessity if you want to make life easier on yourself. I've used this installation
kit a couple of times now and it works great.

Missing Vital Technical Service Bulletin

Written By Nelson, Simi Valley, CA on Friday, March 11, 2011

Crutchfield Customer Review (What's this?)

Bought this with a Pioneer Z-120BT to install in my 2006 Ford Mustang GT with Shaker 500 factory audio system. Wiring diagram was straight forward, and there seemed to be no problems with its integration. But I soon discovered that the headunit would reboot at higher volumes, specifically when heavier bass was present. I completely undid my installation on two seperate occasions to try and find what was wrong. I almost sent the headunit back to Crutchfield because I believed it was defective.

What was defective were the instructions for this adapter. After MUCH searching on the internet, I discovered there is a TSB issued for this unit that addresses the exact issue I was having. A 1 amp diode needs to be soldered into a specific line to keep voltage being fed back by the subwoofer amps, which either momentarily disables the sub's or makes the unit reboot.

It's very frustrating to realize how much time I've wasted for nothing, when they could've included this information just like they address the ground loop isolator and rear seat entertainment system issues. So this unit gets four stars because I have to modify it when it's brand new, and one star for the incomplete documentation. Most disappointed, but at least now I know what's wrong.

[Editor's Note: Thanks for bringing this to our attention. We have confirmed this information with PAC, and added it to our database.]

Makes navigation install simple

Written By JOTN, Virginia Beach on Thursday, February 24, 2011

Crutchfield Customer Review (What's this?)

This sure made a navigation install simple. The last one I did, it took me all
day to run wires into the engine compartment, back to the trunk, and to the
parking brake. This has them all right where I needed them by pulling the
information off the CAN-bus.

Parts not needed

Crutchfield Customer Review (What's this?)

This expensive wiring harness was recommended to interfac with 2006 Musang with
Mach 500 system. The instructions were terrible, so much that I had take it in to Best
Buy and pay them to install. This wiring harness had parts for interfacing RSE and SWC,
all of which were not needed and have never been an option for the car. Bottom line, I
had to buy the normal wirng harness from Best Buy for $20 which worked just fine.

2005 Ford Five Hundred Hot-Setup

Written By PTN, Abington, Pennsylvania on Monday, October 18, 2010

Crutchfield Customer Review (What's this?)

This is certainly an excellent product. Being able to properly solder and insulate all connections between this harness the harness of the head unit (Kenwood KIV-700) while in the comfort of my workshop is without a doubt the way to go. Once the connections are made, installation of the unit itself was only about an hour or so. Instructions / diagrams are pretty good. Most of the wire's color codes actually matched up with the head unit. It was all too easy. Triple checked for mistakes and it worked perfectly. I'm not a big fan of an extra set of "connectors" between the head unit and everything else, but the time and aggravation saved with this set up is well worth it. Now, when I want to re-install the stock double-din head unit, it should only take a few minutes. Make sure you order this harness WITH (at the same time) your new head unit as the price will be half. I did not, however Crutchfield graciously refunded the difference. Finally - if you have steering wheel controls like I do on the Five Hundred Limited - order the PAC SWI-JACK and perform the install at the same time. Most of the original steering wheel functions will be preserved. This complemented the installation making it truly the "Hot-Setup

5 stars for sure

PAC C2R-FRD1 With JVC KW-XR610 Install

Written By 2005 Mustang GT, Greenville, MS on Friday, July 23, 2010

Crutchfield Customer Review (What's this?)

The PAC C2R-FRD1 was needed to use the factory subwoofers that came with the stock shaker 500 system in my 2005 Mustang GT. I think every wire color matched between the PAC and the JVC KW-XR610. All I had to do was slip on heat shrink tubing and solder the wires. This was reassuring, since this was my first stereo installation in 18 years. The PAC worked well, the stereo sounds great, and I can upgrade to a DVD navigation receiver in the future. Since Crutchfield cut me a price break on the PAC because I purchased the PAC and the JVC stereo together, I have nothing to complain about.

Makes life much easier

Written By Mike, Canton, OH on Wednesday, May 26, 2010

Crutchfield Customer Review (What's this?)

I purchased this along with my new Kenwood DNX6160 for my 2007 Fusion. It allowed me
to wire up the head unit inside at my leisure, and physically install it in the car in a few
minutes. The included instructions, while not robust, are clear and concise, and don't
require "overthinking".

Since it requires no splicing whatsoever of any OEM wiring, I can revert back to the stock
head unit whenever I please, without needing to purchase any replacement parts or cut any

Lack of Precise instructions

Written By Mike, New Jersey on Tuesday, May 11, 2010

Crutchfield Customer Review (What's this?)

Besides the issue of instructions (or lack there of) item is OK.

My issue is with the connection to my car's VSS (vehicle speed sensor). Diagram shows
the wiring and instructions brag that there is a wire dedicated for this, but NO WHERE is
there any comments about when and WHEN NOT to attach this wire. If you attach this
wire and your radio does not need this connection, you might face the many hassles I
went through including the additional time my vehicle was at the installer and the extra
costs I paid as they swapped items out trying to figure out why my 2008 Mustang GT
started having trans problems as soon as radio was installed. BAD TRANS PROBLEMS.

Maybe the installer should have know this before they hooked up the wire as Crutchfield
suggests...maybe not, but as they told me....the instructions are suppose to be easy
enough for anyone to install. There's no way I would have figured this out if I'd had
installed it myself.

As far as the PAC is concerned, I feel you read a sentence and flip a coin to decide if it
fits your needs or not and go on to the next sentence...rinse & repeat.

Can't be easier!!!

Written By Gerald, Orlando, FL on Tuesday, June 23, 2009

I purchased this interface adapter that was recommended by Crutchfield, while everyone else told me not to buy it, that I didn't need it...

NOT SO!!! This is a must have if you plan on installing a new head unit in your 2008 Mustang. This harness/interface kit makes the install a breeze and just so much easier. You just join the new radio harness to this one and just plug away. Everything you need is there, even the speed, reverse, and ebrake sensor wires. You don't need to fish for any wiring. Its all there and its all plug in. I am so glad I got it!!!!!

PAC C2R-FRD1 Wiring Interface

This item is a must for any aftermarket HU install made it simple I just soldered up all the like wires by color code and plugged it in. Everything worked perfectly. My HU is a Pioneer avic z3 in a 2006 ford Mustang Gt with stock shaker 500 speakers in the doors and Pioneer premeer speakers in the back deck and two 10" JBL subs in the trunk with a Jbl 600 watt amp. I am still using the stock amp in the doors for the shaker door subs. Great sound, and fully adjustable.

Necessary Accessory

Written By Dave, Norwalk, CT on Thursday, October 16, 2008

Crutchfield Customer Review (What's this?)

I had to purchase this for my 2006 Mustang with the Shaker 500 system. It worked fine. However, it would be nice if I didn't have to use it at all. Crutchfield says they provide (for free) what you need to install your equipment. Apparently I needed this adapter but it wasn't free. Hmmmmm.....

Also, I purchased a Kenwood head unit for my 2008 Ford Escape (on Audiophile standard radio). Crutchfield sent me "everything I needed", including a harness with one connector on it. However, after I pulled my dash apart and removed the factory radio, to my surprise there were 3 connectors. With the power on, I pulled each one out and discovered that all 3 connectors were needed for the system to work. I called Crutchfield and they informed me that I would need another one of these PAC C2R-FRD1 interfaces. Again, not for free.

Product Research


Overview: The PAC C2R-FRD1 is an essential installation accessory for select 2005 and up Ford / Lincoln / Mercury vehicles with MSCAN databus radios. Using this interface will enable factory features such as rear seat entertainment (RSE), rear seat controls (RSC) and the THXII amplifier when the original radio is removed. Other features of the C2R-FRD1 include data bus driven retained accessory power (RAP), vehicle speed sensor (VSS) output, illumination, reverse output, parking brake output and a 5-volt regulated amp turn-on for factory installed subwoofers. The C2R-FRD1 also makes use of the factory AUX input jack (if available).

Steering Wheel Controls: If your vehicle has steering wheel controls (and the aftermarket radio is compatible) they can be integrated using the optional PAC SWI-RC steering wheel control interface (541SWIRC, sold separately).

RCA Filter: The audio signal coming from the RSE in Ford/Lincoln/Mercury vehicles is a differential output. Some auxiliary inputs on aftermarket radio have a common ground input that causes distortion in the RSE audio. The audio distortion can be fixed by using the supplied ground loop isolator (SNI-1) between the RSE output from the C2R-FRD1 and the aftermarket radio's auxiliary input.

Compatible Vehicles: The PAC C2R-FRD1 is compatible with the following Ford/Lincoln/Mercury vehicles.

  • 2005-2007 Five Hundred, Freestyle, Montego
  • 2005-2008 Mustang (Shaker 500 and 1000 included)
  • 2006-2008 Explorer, Fusion, Milan, Zephyr, Mountaineer
  • 2007-2008 MKX, MKZ, Navigator, Sport Trac, Edge, Expedition
  • 2008 Escape, F-250, F-350, F-450, Taurus (X), Marnier, Sable

Note: 2008 F250/350/450 with XL trim package are not compatible. If the vehicle is equipped with the Sony factory stereo system, adjust the fader to your preferred front/rear setting before the factory radio is removed. Neither the aftermarket radio nor the C2R-FRD1 interface has the ability to adjust the factory amplifier's fader. Please see Crutchfield's "Outfit My Car" to confirm your vehicle's compatibility.
