About the Metra 70-1860 Receiver Wiring Harness

Metra 70-1860 Receiver Wiring Harness

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

Metra 70-1860 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 makes installing your new stereo easier, and allows you to put the factory radio back when you sell your vehicle or return it at the end of the lease. 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:

Note: If your vehicle is factory equipped with an external factory fader (which isn't part of the radio itself), use two of the included speaker plugs. Connect them to the new receiver's front or rear speaker wires. The factory fader will be used, not the new receiver's. If your vehicle has a power antenna, you'll connect the new receiver's power antenna turn-on lead to the female spade connector in your vehicle. This connector will be on the end of a blue wire, which may be covered with black tubing.

Very, very incomplete

Steven from Portland, OR on 4/29/2019

1990 Mercedes-Benz 350SDL

Verified customer (What's this?)
Verified employee purchase (What's this?)

1990 350SDL (V126) The power/ground plug matched the wiring in my car but none of the speaker connectors were of any use whatsoever. I have researched this extensively and depended on the favorable reviews here to determine that this would probably work on my car. I should have paid more attention to the various Mercedes forum posts that told me this would be a bigger undertaking than Crutchfield led me to believe. I am going to end up paying someone rewire the whole speaker system in the car. Not happy. You would think that someone would have figured this out after 29 years.

Pros: Power plug fits

Cons: factory speaker/amp connections aren't supported

Crutchfield response on 5/7/2019
We're sorry that you feel we let you down, Steven. In checking the notes on your order, it appears we displayed this note when you purchased your Kenwood receiver for your Mercedes: 'When installing a new stereo, you'll need to run new speaker wire to each speaker.' We like to make sure customers see this crucial information for any installations that will require some additional work.

I used the adapter plug and speaker adapters to avoid having to cut up the original wiring of my 1988 Mercedes 560SL. I still have the original stereo. The adapter let me solder the new stereo wiring in the comfort of my shop, and the installation was a breeze. Really liked the product!

Cleverly designed to fit the Mercedes!

bnobob from Georgia on 1/11/2015

Verified customer (What's this?)
Verified employee purchase (What's this?)

I used this harness to wire in a Pioneer KEH P-2030. The designers were clever. I did not need to cut one wire, merely connect the 2030 wires to this adapter harness! ( I did however, need to fab up a 5" piece of stranded wire w/ 1/4" spade/male lugs on both ends, as the radio wire was a tad short, but that was on the Pioneer connector harness. ) Just wire this ganglion up to the P-2030 connector wires, and snap everything in place! No wire cutting inside the Mercedes (mine an 1989 300E) console. Top notch! BTW: I didn't use crimps, or electrical tape. I did a 3/4" twisted splice, and had heat shrink on the wire, that I then slid over the soldered joint. Made the harness slick and thin. Then finished off with Ty-Wraps.

Pros: So easy !

Cons: Would have been neat for them to add the 5" auto radio/antenna wire.

This harness works perfectly and lets you install a new stereo head without cutting a single wire from you factory wiring harnesses. Be sure to solder all connections and use heat-shrink tubing sleeves to prevent shorts behind the dash. Install was in a 1987 Mercedes 300D (W124 chasis).

Pros: Connects perfectly with the Mercedes factory wiring plugs..... installation is a piece of cake and you don't cut a single wire from your factory harnesses.

Cons: NONE

Very easy to read & set up. All the colors matched up w/the stereo wiring harness. I did all my soldering & shrink sleeving outside the car. The excpetion was for the two to one ground wire. Wires are thin but strong.

Pros: Length of wires. Ease of understanding instructions. All colors matched.

Cons: Ground wire needed to be cut down to same length as the others. Very minor.

Mercedes Wiring Adapter Harness

Crutchfield customer from Florida on 8/28/2013

1984 Mercedes-Benz 380SL

Verified customer (What's this?)
Verified employee purchase (What's this?)

My installation was on a 1984 380 SL [1983 & 1985 will be the same] High quality harness. Splice this harness onto the connector that comes with your aftermarket radio. On the Sony radio I installed, the main harness color codes matched perfectly. FYI, the instructions that come with this harness make no mention of connecting the power antenna control wire, as that function is not controlled by this harness. The blue/white wire on my radio connected to it. Best to obtain the install manual for your radio and obtain a copy of the wiring schematic for your Mercedes stock radio. This can be obtained from AllData.com or Mitchell OnDemand. Also available from most auto repair shops which have this software [in case you have a mechanic friend]

Pros: High quality components. Comes with speaker adapters for 4 speakers, in case you need that many.

Cons: none

Verified employee purchase (What's this?)

The harness came with instructions, well made, was super easy to solder up with my Pioneer Wiring harness then made my install pretty plug and play with one small exception. The 1986-87 300D Turbo has a physical fader in the instrument panel and the instructions are for wiring it with the fader still in play. It would be nice to also have some instructions on how to bypass the fader so all the speakers function discreetly.

Pros: Easy, Well Made

Cons: Only one method of install provided in instructions.

I bought from Crutchfield because of their vehicle-specific instructions and harnesses. The harnesses worked great and I did not have a problem with them; I did not have to cut any of the OEM harness.

Pros: Fit and work great; recommended.

Cons: Instructions and vehicle-specific information could be improved with very little effort and , since this is a major value-adder for the amateur customer-installer, it will be worth it to you.

Verified employee purchase (What's this?)

I used this to install an Alpine ida-x305 into a 1985 Mercedes 300D with the factory radio/cassette without amp. Worked fine. On this model car it's a little weird that there's a front/back fader in the center console, so you're really only wiring two of the speakers out of your stereo. Unless you want to run new speaker wires, which I didn't feel like. But, the harness does exactly what it's supposed to.

1992 Mercedes 300td 2.5 (300d and E classes similar) The power leads make things easier. The speakers need to bypass the old amplifiers except for the subwoofers in the door. I took an RCA off the front preouts ran them to the amp and cut soldered the rca to the amps to get subs to work. The 4 main speakers need to be directly wired. Also this car uses a powered antenna so that blue wire (accsessory power) needs to be run to the trunk.

Mercedes Benz 300D radio wiring harness adaptor

Rick from E. Longmeadow, MA on 2/10/2008

1992 Mercedes-Benz 300D

Verified customer (What's this?)
Verified employee purchase (What's this?)

The radio wiring harness adaptor is correct. I do not need the small female jacks. I had to wire skpeaker wire from the sony radio to the old amplifier speaker output. That means I bypassed the old amplifier. They work perfectly. My car is 92 Mercedes Benz 300D same as 300E. Thank you.

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 vehicle's 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 and sold separately.

A
Not sure I need them for my current installation, but it's always good to have spare parts that match my car (an 80s Mercedes). I find that these older German connectors have differences in fitment as compared with the electrical connections I can get in the US. [ William  Dec 14, 2018 ]

A
The wiring harness is a necessity since I don't wish to cut any wires. My local Audiotronics didn't have the harness for my 1990 300E. My plan is an 8" sub/amp combo and a new head (Pioneer MVH-X381BT - purchased). Larry was a huge help in getting all of the equipment I needed, and stuck with me through all of my questions; I'm definitely coming back to Crutchfield for future...anything honestly!
