Product Research

Wiring Harness: This wiring harness 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 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 SWIC adapter is required & sold separately.

Customer Q&A

2 questions already asked

Q
My aftermarket head unit doesn't have Rca on back but has multiple red& white rca if you were to add an amp etc. Do I plug in to those or do I need to buy another regular harness without rca ends as well?

Greetings Roger, and thank you for your question. The RCAs on this harness are to be used when a certain vehicle has a factory amplifier, and in order to retain that amplifier, the harness needs to have RCA connections. In order to use this harness, your aftermarket stereo needs to have front, rear, and subwoofer RCA preamp outputs. For other possible options, please call one of our advisors at 800-324-9695 with your vehicle information.

Q
the part number you show for this item is that of the harness for just keeping the factory subwoofer and aux jack in place. the picture shows several adapters it seems. can you specify what the price here includes?

I forwarded your question to an Advisor and they responded with the following: The harness includes connections to keep the factory amplifier. The new stereo must have 3 pairs of preamp outputs to connect to the harness. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat.
