Crutchfield custom wiring harnesses are lifesavers. You'll save many steps when installing an aftermarket receiver in your car. Simply splice the color-coded wires on your Crutchfield harness to the wires from your aftermarket radio — and do it in the comfort of your home without having to struggle with splicing wires behind your dash. Most of the wire splices can be made on your work bench or kitchen table. Soldering is best, crimping is also very popular.

Next, simply plug the Crutchfield harness into the harness that you removed from your factory radio.

Since you didn't have to cut off your car's original radio connector, it's easier to put the factory radio back in when you sell your vehicle or return it at the end of the lease. Just plug the factory radio back in and keep the aftermarket radio. Best of all, the harness is free with most of the receivers Crutchfield offers. 30-day warranty.

Connections:

Note: The speaker negatives are electrically the same for the left and right side speakers. Most aftermarket receivers (and all that Crutchfield sells) will need an additional adapter, or you may run new speaker wires from your receiver to the speakers. In addition, you'll need to make a ground connection between your new receiver and your car's chassis.
