Metra 70-1776 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.


What's in the box:

  • Power/ground harness
  • Speaker wire harness
  • Amp turn-on/Subwoofer harness
  • RSE harness
  • NAV/SWC harness

I bought this for the same setup in my o3 Eddie Bauer. Works great. Crutchfield has it with the double din kit. Also has the kit for the back video screen that comes with it.
