Metra 70-1784 Receiver Wiring Harness

This vehicle-specific wiring harness makes connections between your new car stereo and your car's electrical system.

First, attach the color-coded wires on your Crutchfield-supplied harness to the wires from your new stereo. If you're not using a soldering iron, we recommend that you purchase some wire connectors to secure the connections. Check out our handy article on three ways to connect the wiring harness here.

Now, once this harness is connected to your new stereo, you'll be able to plug right into your car's factory radio connector. This harness saves installation time since you won't have to cut factory wires individually, and this also enables you to re-install the factory radio if needed. A detailed instruction sheet comes with the harness. Warranty: 60 days.

Please read this important note: This harness may not contain provisions for every wire needed to complete your installation, and it will not accommodate special navigation, video, or factory steering wheel control connections. You will need a special adapter if you want your factory steering wheel audio controls to work with your new stereo.

Connections:

  • 12V constant power
  • 12V switched power
  • chassis ground
  • dimmer
  • left front speaker +/-
  • right front speaker +/-
  • left rear speaker +/-
  • right rear speaker +/-

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.

Made to make your life easier but apparently not.

Written by: Misha T. from ocean city, MD on February 12, 2016

2002 Volkswagen Passat
Crutchfield Customer Review (What's this?)

All the wires are marked for you. Supposed to made an installation easier for my VW Passat 2002 but connectors coming out from my car didn't fit the connector on this Harness so I had to manually cut and connect each wire instead. The product was useless to me, just waste of money. Nothing wrong with the product, just didn't fit my car. Other than that - ok.

Pros: Suppose to make your installation easier. BUT before you get it, make sure it fits the connection in your car!

Cons: none

Fits mk4 great,although a tight fit

Written by: Spencer from Iowa on January 11, 2016

2001 Volkswagen Golf
Crutchfield Customer Review (What's this?)

I used this for my 01 mk4 golf and it made installation a 10 min job.I did not need to switch wires or add any for my factory amp to work normally. Only thing that is bad is this plug is large and you will have to tuck the wiring into any in dash cavity before you can slide your stereo all the way in. But great plug and play harness

Pros: Ease of install

Cons: Have to squeeze harness into dash to install head unit all the way in

Written by: dissapointed from California on January 8, 2016

Crutchfield Customer Review (What's this?)

Tried this because Crutchfield says they have a MasterSheet for wiring. its a generic diagram not specific for my 2005 vw beetle convertible with monsoon and no cd changer. although they say "compatible with your vehicle. Yeah--Not! Don't waste your time with Crutchfield!

Pros: connects to oem harness color coded wires match new alpine stereo harness

Cons: wires match new stereo but obviously have Not been tested by their "professional installers"

Dodge Sprinter 2004 Requires Change

Written by: bluecuda from North Carolina on November 28, 2015

2004 Dodge Sprinter
Crutchfield Customer Review (What's this?)

Really a great product, but required a change for my application. The [Ignition} and [Battery] wires needed to be reversed. The head unit worked fine but the memory (example being the radio stations you preset) were lost every time the the ignition was turned off. You can either mismatch the wiring color codes and reverse them or remove the pins and switch them. I took the extra time to reverse the pins to keep the color coding on the wires correct.

Pros: Direct plug in, easy to install

Cons: Required wire changes on my 2004 Dodge Sprinter

Had to be Modified for 2003 Mercedes CLK430

Written by: DD from Georgia on September 24, 2015

2003 Mercedes-Benz CLK-Class
Crutchfield Customer Review (What's this?)

This item was specified as compatible with my 2003 Mercedes CLK 430. Well the molex connectors are the same as what is in my car, but the yellow, black and red wires are not in the right position. I had to track down a wiring schematic for my car and remove those 3 wires and relocate them in the connector, as well as add the blue/white wire to turn on the factory amp. This item caused me a lot of grief, including returning a head unit thinking it was DOA because the red wire had to be tapped into a 12v ignition acc wire on the cigarette lighter before the unit would even power on. The instructions for the blue/white wire say to not use on vehicle newer than 1999. This is absolutely not the case for the 2003 CLK 430.

Pros: The speaker wires are in the right place.

Cons: The yellow, black and red wires had to me moved and the blue/white wire was required despite what the directions specified.

Crutchfield advisor told me this is what I needed. I am always a bit skeptical, so I went over the schematics for the HU that I was installing (Jensen VX7022). Everything checked out. An easy and perfect wire-up! (might not be the case with post 2000 MK4 VWs, but for my car I didn't have to run ANY additional wires).

Pros: Perfect!

Cons: None.

Written by: CHalloran from Schenectady new york on January 25, 2015

Crutchfield Customer Review (What's this?)

Was the exact harness required for my car. The wiring was simple and quick.

Pros: Color matching took a few minutes to wire together with the receiver and this harness. It was a cinch. Had the whole thing installed in my car in no time at all.

Cons: A little bulky for a beetle. Took some serious knuckle bruising manoeuvering to get it to where the reveiver would sit in properly.

Crutchfield Customer Review (What's this?)

The Metra 70-1784 Receiver Wiring Harness was a perfect fit for my 2000 MBZ C230 and the wires matched up to my new Kenwood. Easy install due to perfect fit and direct correlation of speaker wire colors. Kit provided two additional wires for remote amp and power attennae and I had to use one of them. Highly recommend for anyone doing their own install.

Pros: perfect fit and exact correlation to speaker wire colors on head unit. Notices for differences in constant power and switched power comes in instructions.

Cons: None at all.

Made the installation much easier. Matched existing audio plug. Plug and play made easy.

Pros: Matched existing plug in car. Wires were plenty long enough to connect to radio plug.

Cons: Not all wires were in the right location for hook-up. There was no electrical diagram sent for plug or for the car it was to be installed in. Had to make a couple of calls to crutchfield to get the right wiring diagrams. They were very helpful.

Car Battery drained

Written by: Matt from Cleveland, Ohio on June 26, 2014

Crutchfield Customer Review (What's this?)

Will not work with Monsoon Radio. Amplifier in trunk will stay on and drain car battery overnight. Looked in VW Passat forums and this is a common problem. Only solution is to wire up a relay to switch 3 power wires to turn off with ignition switch. Locating the correct wires is hard.

Pros: Radio and CD works

Cons: Car battery will be dead in the morning

Crutchfield response on July 1, 2014 This is a known problem that occurs with some Monsoon systems. The amplifier in the Monsoon system doesn't have a dedicated turn-on/turn-off wire, so it depends on the specific amp as to whether this problem will occur. The solution is to install a relay to turn off the amp. Our Tech Support team is familiar with it and can advise customers on how to fix the problem.

Ford Focus with factory Blaupunkt adapter

Crutchfield Customer Review (What's this?)

This wiring adapter worked great for adapting my Ford Focus 2003 factory Blaupunkt unit to my Pioneer stereo. There were only two wires to switch and the instructions I got with my purchase it told me which wires and for which cars. I soldered this adapter to my plug for my Pioneer unit and then just plugged it into my cars harness.I then just plugged in my Pioneer unit and every thing works great. The Pioneer unit I have does not have any the auto volume control for vehicle speed like my Blaupunkt had, but if it did, you would need another adapter for this feature. I understand it also is available from Crutchfield.

Pros: No need to cut up cars wiring harness. Easier to connect or solder wires at the table rather than in the dash. You can always easily plug the old stereo back into the car.

Cons: None

The Winnebago Rialta is based off of the 2003 VW Eurovan but has a different harness then the one provided by Crutchfield. It looks like this is due to the different 12v setup of the motorhome (runs of the coach batteries instead of the car battery.) This adapter will not work in the Winnebago Rialta.

Pros:

Cons: Does not work in the 2003 Winnebago Rialta

Crutchfield Customer Review (What's this?)

I went to replace my stock head unit in my 2005 GTO only to find out that in order to do this I needed a Voltwagon wire harness. A friend lead me to crutchfield and I was having an issue finding a metra part number on the website so I gave them a call. I called as I was viewing their website and the representative told me to go to the bottom of the page and read her the number, I hit the refresh button and BOOM all three parts I needed for my car were right there on my screen. My mind was blown! This was the first time I swapped a head unit so I made some phone calls during the swap and they had an answer to every one of my many questions. Best customer service, hands down!

Pros: Everything

Cons: Can't think of one thing.

Crutchfield Customer Review (What's this?)

Thank you CrutchField for including this item with my deck. Made the installation a snap. I gave it a 4 as the directions could be a little clearer. A quick phone call to tech support solved my problem (pink Amp On wire connection was not clear, at least to me). Switching the Yellow and Red wires for my application was a bit unclear as well. Yes, switching the wires is the right thing to do, but the instructions define the wire connections as to which one goes to ignition and which one to constant 12V. Following that after testing with my multimeter leads to incorrect connection.

Pros: Free with purchase. Easy to install.

Cons: Directions a bit unclear for a total novice.

Wire Harness worked perfectly

Written by: Mark from Moorestown, NJ on December 31, 2012

Crutchfield Customer Review (What's this?)

The wire harness was used on a 1998 Mercedes ML320. I am always a bit apprehensive about finding compatible aftermarket products for Mercedes because it seems there really aren't too many out there. But this wire harness was absolutely perfect. The instructions provided by Crutchfield provided easy-to-follow and detailed directions on how to correctly connect the wires in the harness to the wire harness of the radio I purchased (Sony MEX-BT3100P). The only flaw I found was that the directions incorrectly stated that the factory connector in the Mercedes needed to be cut in half in order to properly mate with the connector on the wire harness. I happily found that this wasn't necessary - perhaps the wire harness has been updated since the instructions were written. I was worried that the installation of my stereo would be complicated and take hours but it only took me an hour and a half including the time it took to solder the wires in the harness to the wires from the radio.

Pros: Great instructions by Crutchfield made using this harness easy and fast!

Cons: None

The wire harnesses from Crutchfield never disappoint. They are one of the reasons I shop here. They make the job fun rather than painful, while maintaining your factory harness. If you still can't figure it out, Cruchfield support will blow you away with their knowledge. I bought a used car and a hacker had chewed up the factory harness. The Crutchfield tech told me what to look for and got me through it.

Pros: If your vehicle has special wire requirements or differ from a normal install, they'll include specific instructions telling you exactly what to do.

This item plugs into the harness for our 2010 Sprinter van, however the sprinter uses the CanBus system. if you use this, you will still have to run switched power and dash illumination. I ended up using an XSVI-1784-NAV to hook up our nav unit. if you don't have a nav unit, the XSVI-1784 will work as well for a little cheaper.

Pros: will get your speakers hooked up as well as ground an constant power.

Cons: will not provide switched power in a sprinter van.

I bought the harness to use on a 1999 Mercedes 320 ML. There was one wire that was not connected correctly. The blue, 12 V wire for the radio antenna amplifier out of the radio needed to be connected to the tan/light brown wire on the Merceds plug. Without 12 volrts to the antenna amp, I received no AM reception. I used a pair of needle nose pliers to move an unused wired over to reconfigure the plug and all was okay. Other than that, the plug is a wise thing to use and generally makes the installation slick. Perhaps the wrong plug adapter was sent to me, but I doubt it

The harness fit perfect with only one problem. With the Monsoon system, my amp was drawing power from the battery when the car was off. There was nothing on the harness let alone instructions on what to do about this. Had to disconnect the amp and rewire the speakers to by pass the use of the amp. This was annoying and frustrating. I don't really blame the harness or crutchfield's instructions, but maybe add something on what to do about this. Overall the hardness fit and worked well minus this amp problem.

install a new head unit and still utilize the factory amp that powers the
mid/bass speakers in the front doors. This is that product!!! I did swap the
red and yellow power wire positions at the connector so that the constant and
switched power works properly for my car as the included instructions said. I
also hooked up the amp turn-on wire from the new Alpine deck to the power
antenna wire on this harness because on my car the power antenna wire is also
the factory amp turn-on. The system works flawlessly and sounds a million times
better than the original with no wires having to cut. Thanks Crutchfield!

The harness just simply works as advertised. Installed it in my 2001 VW Jetta that came
with a Monsoon sound system. Very easy to install because of the included Crutchfield

length of the harness cable and the cable from the receiver combined was a little long,
but it fits inside the dash okay. One can trim the cables a little shorter for easier

2001 VW Jetta w/ Monsoon Sound System

Written by: Matt J from Connecticut on August 22, 2010

This adapter worked great when I replaced the head unit in a 2001 VW Jetta which
came with a factory equipped Monsoon Sound System. An Internet search prepared
me for all types of wiring problems when replacing the HU, but this wire harness
plus Crutchfield's included directions made everything go smoothly.]

The Monsoon Amplifier turns on/off as it is supposed to, works with the regular
line voltage from the HU, no problem with speakers.

The HU gets plenty of power from the car's wiring system (and doesn't need a
dedicated wiring connect to ground and an empty spot on the fuse panel).

Follow the directions closely and leave the two extra wires unconnected (but
wrapped in electrical tape) so there are no problems when the dealer uses the
car scanner computer.

Instructions were clear and easy to follow. I agree with others that you need
to shorten the leads as much as possible because there just isn't much room in
the dash of the New Beetle for all those wires! I spent the most time during
the entire installation process just trying to get all the wires into the dash
far enough to let the stereo slide in. But that was more the fault of VW design
of stereo compartment rather than the wire harness itself. The plug end is kind
of big and boxy, but I don't know what else they could have done other than have
two individual plugs instead of one big one. However, the wire harness came free
with the purchase of the Clarion CZ-500, so I guess I shouldn't complain too much!

Crutchfield Customer Review (What's this?)

This harness was a huge timesaver. We used it initially by plugging it into the Jetta speaker harness (there are 2 radio harness connectors in the car, one for the speakers, and one for everything else). Then we used the supplied diagram and a DVM to verify the proper color wires were in fact, the right wires for each speaker.

Once that was done, we removed the harness, put it on the bench with the harness from the radio, and started wiring them together. The great thing was that our new Pioneer radio harness used the SAME colors for each speaker and function as did this harness. So in the end, we just matched colors on both this harness and the radio harness, and soldered them each together!

When we were done, we had a custom amalgamation of 2 harnesses, which fit between the radio and VW harness connectors. Take it back to the radio, plug it all together, and go. The instructions clearly label each wire, it's function, and include some extra instructions for certain car models, where particular wires have other functions.

This made installation easy, and the instructions that came with the harness made everything simple. The Volks wiring space is very compact, so make sure to tuck everything down below where the deck sits, there is space there and it is just enough to fit. If you do this first, it will slide in first time, and the installation will be a brease. If you pass this up, get ready for a frustrating experience!

Thanks Crutchfield!

Used for 2002 Land Rover Freelander SE

2002 Land Rover Freelander
Crutchfield Customer Review (What's this?)

Bought to install a Pioneer DEH-P790BT (same as the P7900BT but with the i200 iPod cable included) and a PAC SWI-PS. Note when I tried to outfit my car, the site here didn't have much on the 9 speaker factory installed system. I found that the 9th speaker is a subwoofer that is driven with the rest of the speakers by an amp that is powered as 12v switched by the factory unit. There were three errors in my initial pass:

1. The yellow wire on this harness does not connect to 12v constant on the Freelander but to 12v swithed.

2. The red wire on this harness does not connect to 12v switch but to the Freelander's 12v constant.

These were easily switched around once tested with a multi-meter.

3. The pink wire should be connected to 12v switch to drive the amp on the 9 speaker system. In other words, you need to power the amp as the factory unit seemed to power it by default.

On the Pioneer unit, the lead wires were a little short and while I thought I was good at crimping, I goofed a few times costing me valuable wire length.

The harness also adds some bulk to the entire unit installation including the PAC SWI-PS controller I purchased to allow me to continue to use the steering wheel controls. It was definately a tight fit.

The BT mic was also a bit tricky to route. I put it just above my rearview mirror, down the left colum, next to the fuse box, under the driver's carpet, and up the center console.

Overall, definately worth it, especially since it makes installing much easier than trying to crimp or solder at the dashbaord.

works great, but a really tight fit!

Crutchfield Customer Review (What's this?)

The wiring harness made installation much easier in my 02 beetle with the monsoon system! But, you do not have much room for the size of the plug, so plan on working the plugs into one of the little areas underneath the radio. Make sure you leave enough lenght on the wires before you cut! Overall highly reccommended though.

Made easier by the fact that, for my in-dash receiver/CD player, the colors of the wiring matched almost perfectly.

This harness works

2001 Volkswagen Beetle

The other review on this wiring harness is somewhat correct. The space for the radio is very small - VW designed this space to hold their radio with their wiring harness and not much more. However, there were "pockets" under the radio compartment that I was able to slide the harness and bigger non-factory plugs into, to make the radio fit very snug. I used it on a Sony 8815X head unit and the Monsoon audio system in the Bug. It is an amazing radio now! Thanks Crutchfield!

Harness too bulky

Written by: Rafael from Spain on February 20, 2005

Crutchfield Customer Review (What's this?)

This wiring harness is too bulky to fit my stereo in the original location. The stereo I bought takes up all the room in the dash opening, and there is little room for the wiring harness to be installed. I didnt want to remove any other dash paneling to accomodate for the wiring, so I decided not to install it. The stock wiring plug was perfect match for my aftermarket stereo, I just had to swap the 12V constant and Accessories wires positions to match my new stereo.

Features

Crutchfield Wiring Harness: Crutchfield wiring harnesses prevent you from having to cut your vehicle's factory radio plug when replacing your factory radio with an aftermarket head unit. Simply solder or crimp the Crutchfield wiring harness to your aftermarket head unit's harness (solder & crimps not included), plug the aftermarket head unit's plug into the rear chassis of the aftermarket head unit, and plug the Crutchfield wiring harness into your vehicle's factory radio plug.

Note: Installation tools, hardware, & accessories are not included & sold separately. Please see the Accessories tab for recommendations & availability.

Wiring Notes: If the Crutchfield wiring harness is not equipped with a ground wire, you will need to ground the aftermarket head unit's ground wire to the metal chassis of your vehicle. Some vehicles may require you to bypass the vehicle's factory amplifier (in another location from factory radio) or hardwire certain connections. If your vehicle is equipped with factory steering wheel controls, an additional adapter is required & sold separately.
