About the Metra 70-2002 Receiver Wiring Harness

Metra 70-2002 Receiver Wiring Harness

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

Metra 70-2002 Receiver Wiring Harness

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

First, attach the colour-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.


Note: This harness has three different red 12V switched wires. You'll need to connect only one, which is determined by your vehicle model and series. The included instructions will help you identify which one to use.

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

Product Research


Wiring Harness: This wiring harnesses prevents 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.

Is this harness the correct one with several red wires for my 2000 Saturn Sl? One harness I bought only had one red wire and wouldn't power on the deck.

Hi, I bought the same harness for my 2001 Saturn LW 300 , and It match the wires. What I suggest you do is to take the radio out with the old harness attached and put the new harness next to it and see if all the wires match the colors. If it does you are good to go. Hope thi 'll help Good luck

what is the BLACK wire with a WHITE stripe?

Well, I never figured out what it was for, but I taped it off and didn't use it. It would have been nice if the darn instructions said something other than where the "red" wire goes. Used on a 2000 Saturn SL1.
[ JoeT  May 26, 2014 ]
Joe T, I used this harness for a 2000 Saturn LS1 a year ago. I merely matched everything up, heat shrink and stereo works perfectly. Sorry, I do not specifically remember what this wire was for. Did you call or email crutchfield support ? Sorry I could not have been more help-good luck Bob S.
