Metra 70-1743 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 it 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.


Note: You'll need to make a ground connection between your new receiver and your car's metal chassis.

Gen 1 Montero - perfect fit. Don't be bashful about deleting wires you don't need; for Gen 1s, you can lose the blue wire for a powered antenna, and the orange/white for illumination dimming.

Crutchfield Customer Review (What's this?)

Could not use these adapter connectors with my stealth. I had to but splice the new connector that came the head unit onto the existing wiring. Instructions were sketchy and didn't help.

Pros: Could not use this with the existing connectors in my stealth.

Cons: Did not work for this install and diagrams did not help. Had to butt splice wiring and look up schematics for connections on Internet.

Harness works fine

Jesse from Lexington, KY on 1/16/2012

1990 Plymouth Laser
Crutchfield Customer Review (What's this?)

Installed head unit using this harness in a 1990 Plymouth Laser, this will work with any first gen DSM Mitsubishi Eclipse, Plymouth Laser, or Eagle Talon. Not sure but it may even work with old 3000GT/Stealths. A little funky to wire as some of the + and - wires are on different connectors for the same speaker, just be sure to pay attention. The right rear or one of the rear speakers was a different color than what the manual said and was different color from the head unit's harness but it was the only one that had me confused. All in all a pretty standard easy install. If you use the factory radio retaining bracket from your Eclipse stock radio it will likely ground the radio out, if not just screw that ground wire into one of the mounting screws on the front of the mounting bracket from the stock radio. Should work fine.

Pros: Perfect fit to factory harness and all speakers work fine. This harness is hard or impossible to find in stock at stores, lucky for us we have Crutchfield. Prepare DSM owners to discard your cassette adapters and FM transmitters.

Cons: Diagram and color mix ups could confuse a novice installer. Recommend installing power supply to harness first, insulating power supply wires and ground and then individually connect one speaker at a time ( both + and - for that particular speaker ) to be sure you've got it all figured out before jamming it in the dash.

Wiring was good instructions poor

Roger from Merrifield MN on 7/2/2011

1992 Dodge Stealth
Crutchfield Customer Review (What's this?)

The wiring harness was just fine. But, the instructions for wiring the orange wires seems to be backwards. When I wired the solid orange wire to the white striped orange wire the radio lights would go out when I turned on the cars headlights. I called the service dept. and the tech looked at the diagram and told me to make sure it was wired that way and it should work. I checked and it was wired as instructed and did not work. So, I wired it with the two orange w/white stripe wires together and everything is now working fine.




Hands-on research

Product Research


Wiring Harness: This 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 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 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 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 & sold separately.
