Our take on the PAC RP4-FD11 Wiring Interface

PAC's RP4-FD11 radio replacement interface lets you replace the factory radio in select 2005-up Ford, Lincoln, Mazda, and Mercury vehicles. You'll still retain your factory steering wheel audio controls, rear seat entertainment (RSE) system, retained accessory power (RAP), and the use of your Ford factory amplifier, if present.

PAC RP4-FD11

PAC's RP4-FD11 radio replacement interface lets you replace the factory radio in select 2005-up Ford, Lincoln, Mazda, and Mercury vehicles. You'll still retain your factory steering wheel audio controls, rear seat entertainment (RSE) system, retained accessory power (RAP), and the use of your Ford factory amplifier, if present.

The RP4-FD11 interface eliminates the need for the steering wheel audio control adapter that's usually required for a Ford-built vehicle, saving you some more cash. Warranty: 1 year.

Important Note: You'll lose your fader control if you have an amplified system in your vehicle. The RP4-FD11 adapter does not work with your SYNC system; you'll need PAC's MS-FRD1 adapter to maintain that functionality. See Details for a list of compatible car stereos.

Please enter your vehicle information or call an Advisor at 1-888-955-6000 to find out if this model is compatible with your vehicle.

Note: Most vehicles will require additional installation parts — please identify your vehicle if you haven’t done so. You can also call an Advisor for more information.

Crutchfield Customer Review (What's this?)

I gotta say I never thought I would spend this much on a bunch of wires. I did some looking around town and everyone listed this harness at the same price. I'm glad I got this harness from Crutchfield. It allows me to use my steering wheel controls and made the installation process easy. And, my time is worth something too. This harness saved me a lot of time because it was so easy to wire and install.

Pros: Works great with my 2006 Ford Fusion SEL.

Cons: It is an expensive harness, but the value is certainly worth it.

Pros: Harness is excellent. Phone help was great and fast.

2008 Ford Expedition EL
Crutchfield Customer Review (What's this?)

Totally made the install painless in my '08 Expedition XLT. Of course lots of soldering wires from the new radio to this unit's harness, but then it was plug'n'play after that. This gave me the parking brake and reverse sensing wires I needed for my install, and was able to make the rear-seat audio controls (RAC) work for the radio and volume (as I don't have the SWC for radio) Without this unit I would have had to spend hours figuring out where to splice from the in-car harness and/or fuse block.

Pros: Made my install super easy.

Cons: None.

Some people may not want to pay the price, but honestly I've been installing car stereos and accessories for about 20 years and this made the install in my Milan take less than an hour, well worth it.

Cons: none

Crutchfield Customer Review (What's this?)

With all the options available in cars today this is a must if you want to integrate with as many OEM options as possible, It does take time, sit down and read the instructions carefully. Make sure you have the right tools to make the job as easy as possible, including top end wire strippers and the right connectors (NOT WIRE MUTILATORS), I suggest the Posi-Products 2 piece screw type you can get here from Crutchfield. Buy alot!

Pros: Makes the project easier

Cons:

Great but was missing Acc Hookup

Written by: SoCal Shelby from Los Angeles, CA on April 2, 2015

This adapter kit was top notch for my 2008 Mustang and now works well, Except that it was missing the pigtail wire and pin to hookup to the Run/Accessory Power. I had to jimmy-rig a new wire so that the radio would turn on/off with the ignition key like it should. That was an hour spent researching and fixing. Other than that, I would have given it 5 stars. The instructions were adequate. Be prepared to practice your wiring skills as you will be required to match up and manually connect the blues, greens, etc. In the end, it works great. I initially tried buying another stereo elsewhere but it became a headache trying to figure out the correct adapter wiring kit and brackets. Go with Crutchfield and feel ensured it's all going to fit.

Pros: Fairly simple to install. Worked great in the end

Cons: Missing a pigwire wire and pin. Instructions were more complicated than they needed to be. Could be better tailored for Steering wheel and non-Steering wheel controlled cars.

Crutchfield Customer Review (What's this?)

This device works about 9 times out of 10 when I press the steering wheel controls on my 2011 Ford Escape. I don't know if that's a limitation of the device, the steering wheel controls, or the head unit I purchased. I'm happy it was pre-programmed. The instructions are kind of a mess, I had to call Crutchfield more than once but they saved the day as always.

Pros: pre-programmed Crutchfield Support was great works most of the time

Cons: does not work all of the time terrible instructions

PAC RP4-FD11 Wiring Interface

Written by: Loyal Customer from Oregon on January 8, 2015

2007 Ford Fusion
Crutchfield Customer Review (What's this?)

I bought a Pioneer DEH-X8700BH stereo and this PAC RP4-FD11 Wiring Interface to retail the steering wheel controls for my system. In the years as a Crutchfield customer I've never had any issues with any product I've bought from them. But I guess it was just meant to happen, with this product.

Pros: I've never had the need to use this type of product in the past but I guess it would've been great had it worked. I took my stereo to a professional and have it installed. The guy installing this PAC wiring interface said he's used this product and has always had good things to say about it.

Cons: The issue we ran into was that this PAC unit would not program to my specific steering wheel audio controls, not matter how many times we tried over and over and over again. Again, the guy installing this product said that it was weird that he couldn't get it to work because he's never had issues with it before. So I guess I happen to purchase the one faulty PAC wiring interface. Other than that, I'll take the professional's word on this being a great product.

Pros: ease of installation

Cons: none

Aftermarket interface

Written by: Jay from Austin,TX on November 5, 2014

Instructions are fairly clear, except for the "Blue" wire which states that it only needs hooked up if you have a powered antenna. This should say an antenna with a powered amplifier. This would avoid all confusion. If you are not sure, hook it up anyway. That is my suggestion, not Crutchfield's. I did not hook it up and ended up taking the dash apart twice.

Pros: Works great

Cons: Instructions could use improvement

Crutchfield response on November 18, 2014 This reviewer makes a good point. PAC's wording regarding the blue wire is a bit dated. We forwarded this review to PAC with a suggestion that they reword the wiring instructions. Also, even if things are going according to plan, it's never a bad idea to call our Tech Support team when you're prepping for an installation. We can always confirm and clarify what's needed. Crutchfield Tech Support is free with every purchase and for the life of the product.

09 Ford Flex Upgrade

2009 Ford Flex
Crutchfield Customer Review (What's this?)

Purchased this to upgrade my 09 Ford Flex without sync and navigation. This as very helpful in the wire connection for my Pioneer DEH-6600BS. Had no problem with wiring, but to keep the steering wheel controls you'll have go pay close attention to programming the item before closing up anything. I made that mistake so I had to pull apart everything and program my SWC before finishing up. Other than that the product worked as suppose to be. No major problems. Just need to pay close attention to the wiring diagram.

Pros: Easier hook up than splicing wires

Cons: take a while to handle the bunch of wires, its a bit bulky, but still able to tuck away for the finish

instruction not comprehensible

Written by: Anonymous from Los Angeles on August 5, 2014

Crutchfield Customer Review (What's this?)

easy to wire/instal. Basic (original) steering wheel functions work, but I can not figure out how to modify them for double function. Called tech support and got sort of an explanation (!). still there's no way ... frustrating!

Pros: basic/original functions work

Cons: instruction very confusing/over complicated

Crutchfield response on August 6, 2014 Installing and programming a steering wheel control interface can indeed be a challenge. To add the double function capability (long press/short press), you have to manually program the interface. Our Tech Support team reached out to the customer to let him know that we'll be standing by if he wants to do that. They'll be glad to walk him through the process over the phone. Lifetime tech support comes free with every purchase from Crutchfield.

SWC adapter PAC RP4-FD11

Written by: MarkW from Ham Lake MN on August 2, 2014

Crutchfield Customer Review (What's this?)

I used this to connect a Sony MEX N5000BT to a base model 2010 Mercury Milan. It works as advertised. Hookup was no problem for this ex-Air Force radio electronics technician. My main complaint with this adapter is that it is overkill and overpriced. It included wiring to connect to a lot of other things besides my steering wheel controls. I think Crutchfield is now offering some cheaper and more realistic adapters now and that is a good thing.

Pros: Does what it is supposed to do.

Cons: Overpriced. Includes a gaggle of unneeded wires for systems with rear seat controls (which mine doesn't have).

2007 Ford Fusion
Crutchfield Customer Review (What's this?)

It was easy to hookup and my steering wheel controls work exactly as they should. I used it in a 2007 Ford Fusion with 6 speakers. A couple of the descriptions of the wires didn't match up exactly but you can figure I out, based on their functions. The wires were long enough for the hookups, but a little more length on them would have made stuffing the unit in the dashboard a little easier. It also gives you the ability to program different functions into your steering wheel buttons, but I have not true That yet. Overall, it is a very good product. I would not have installed an aftermarket radio without it.

Pros: Easy to use, keeps steering wheel controls

Cons: Wires could be a little longer

Adapter rocks!

2006 Mercury Mountaineer
Crutchfield Customer Review (What's this?)

This adapter was perfect for my installation of the new Kenwood head unit. I was concerned that its bulk would not fit in the dash cavity behind the new audio unit, but there was absolutely no problem!

Pros: Ease of "plug-and play" installation.

Cons: Directions were somewhat vague in regards to the adaptation of the steering wheel controls. We had to abandon using them as a result. Otherwise, a five star rating would have been easily earned.

Written by: GL from Boston, MA on March 9, 2014

Crutchfield Customer Review (What's this?)

It works ok, but as mentioned in other reviews for this unit in a Ford Fusion the stock console will only show DVD not the clock. Also each steering wheel control press registers on the console and stays there until another steering wheel control is pressed or the car is shut off. I think it should blank out the last command after some 5 or 10 seconds. I talked to PAC and they cannot fix this with a firmware update.

Pros: steering wheel controls are retained

Cons: The output to the stock console should be better.

Double-press doesn't work on 2012 Focus

Written by: Chris A. from Alexandria, VA on September 19, 2013

Crutchfield Customer Review (What's this?)

Programming this guy in a 2012 Ford Focus (without Sync) gave me a headache, but eventually I figured it out. The real trouble was that apparently the double-press functionality for the SWC that they say you can program in simply didn't work. After resetting to default, I was able to alter the single-press, and change my "source" button to a "phone" function that gave me hands-free calling with a JVC AV61BT. Other than the initial fuss, couldn't be happier with the result. Would be nice if the wiring was a bit longer to allow the programming unit to hang further in your dash so it was accessible by popping the armrest assembly vice taking out the head-unit bezel.

Pros: Gives a lot of flexibility for steering wheel control

Cons: Double-press functionality doesn't work on all models.

Overview: The RadioPro4 (RP4-FD11) is a radio replacement and SWC (steering wheel control) interface that comes pre-loaded with amplifier retention and SWC software, navigation based output signals, and firmware that retains all of the vehicle's original safety and convenience features when replacing the factory radio with an aftermarket head unit.

Functionality: The RP4-FD11 interface allows the replacement of a factory radio in select Ford/Lincoln/Mercury vehicles with the CAN-bus system. Using this interface will retain factory features such as steering wheel controls (SWC), rear seat entertainment (RSE), rear seat control (RSC) and, the factory audio amplifier whenever the original radio is removed. The RP4-FD11 also provides data bus driven outputs such as retained accessory power (RAP), vehicle speed sensor (VSS), illumination, reverse trigger, and parking brake.

Note: 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 RP4-FD11 interface has the ability to adjust the factory amplifier's fader. The RadioPro4 (RP4-FD11) does not retain your vehicle's factory SYNC system. SYNC retention requires the PAC MS-FRD1 radio replacement interface (541MSFRD1, sold separately).

Vehicle Compatibility: The RadioPro4 (RP4-FD11) is compatible with select 2005-up Ford, Lincoln, Mercury vehicles with MSCAN databus radios. Compatible vehicles as of 7/13/2012 include:

You will want to contact an Advisor by phone (1-800-324-9695) or online chat to discuss compatibility with your factory system. They will be able to pull up your vehicle and see if this will integrate. If it does not, then they will also be able to discuss other options with you. [ Jeff  Dec 05, 2015 ]  Staff

Yes, this is not necessary for your application. [ JOHN W  Nov 26, 2014 ]
David, I don't now why you would want this PAC RP4-FD11 interface? This is basically for SWC (steering wheel control) and it worked great for me! I didn't spend $149 on it either!!! I just bought PAC RP4-FD11 05-Up Ford/Linc/Merc interface/SWI Item #: 541RP4FD11 for my Daughter's 2006 Milan and it worked GREAT with the JVC KWR500 CD Receiver. You do have to pair them up at the end BEFORE you push everything back into the dash! I would THINK just the Ford/Lincoln/Mercury Kit Late Models, DD or the Ford wire Harness for Ford/Linc/Merc/Hyun 03-up woukld be all you need plus the Chrysler/GM/Ford Antenna Adapt Motorola M to OEM antenna F hook-up. I used to install radios in cars back in the 70's, Boy, times have changes with easier hook-ups with cable plugs! Whew,,,,,,,, my neck would be sore back under those dashes! lol. I had no problems but YOUR hook-up should be easier with out SWC and NO amp! Good Luck and use your cell phone to call their Install Support Team, I am sure they will help you out if you get stuck? [ TOM  Nov 24, 2014 ]
This is just if you have steering wheel switches to turn up volume, source, or change channels. If you do not have those on steering wheel you don't need this item. I have a 2010 Edge with steering wheel controls and had to have this to operate radio from the steering wheel. [ CHAD  Nov 24, 2014 ]
You only need it if you have steering wheel controls and want to use them for the aftermarket stereo. I have the steering wheel control for the stereo but decided not to use this, since i could just as easily reach the stereo. Your cruise control will still work without it, so you will have no use for this. [ JAMES  Nov 24, 2014 ]
I purchased this to retain the steering wheel controls, factory amp, and factory auxilary imput. Without needing those, i dont see any reason why you would need this interface. The regular wiring harness should suffice. [ JASON R  Nov 24, 2014 ]
Actually I ended up returning mine. In the end I could not justify the money and the cuts to the wireing harness for the stearing wheel controls. I can reach the stereo as easily as I can reach the steering wheel controls. I would not expect that to be normal behavior, since my understanding was that this would make your steering wheel controls work like a remote. Not that it would come in as a seperate line-in. This might be worth asking Crutchfield or anyone else running your stereo. On a side note, did you make the same mistake on the wiring so that your stereo does not dim with the interior lights? Ford uses a different wire than the harness shows. I need to go back in and make the change, but waiting until a nice warm day and that I feel up for it. Good Luck [ JAMES  Jan 17, 2014 ]
I was sent this question, but I'm sorry I can't offer any assistance. Mine was in an explorer that didn't have the screen. Put in your car, go to stereos, and click in the top bar. It has "important info" about you particular car. Should describe if that screen will or will not work with an aftermarket radio [ JASON R  Jan 17, 2014 ]
I did have my head unit installed by a local shop this time. My 2012 Escape Limited has the LED screen on the upper center dash as well. Mine shows temperatures, outside temperature, direction and it reads "Audio" and in upper left it reads "DVD" [ KELLY  Jan 17, 2014 ]
I do not have the car anymore but if I remember right, it did knock out the clock function like you say. [ EVAN  Jan 17, 2014 ]
I have a 2007 ford explorer, have no problem......maybe wiring? [ ERIC  Jan 17, 2014 ]
I did some research prior to the install and found that some features stop working intermittently and that the clock feature from the screen does not work. I decided to not use install it because of the integration it requires. Since then I have sold the fusion and bought a new vehicle. Sorry I could be of more help with your issue. You could always try contacting a reputable car audio store. They should be able to help you without any fees. [ NICHOLAS J  Jan 17, 2014 ]
