Question about Alpine 16 Pin Original Head Unit Harness
Hello... I will try and help you with your problem. I am assuming that you have cut the factory harness off in the truck? If you have and you can reconnect it, I would recommend doing this and then you can purchase a wire harness adapter and then just match the colors. The benefit in using an adapter harness is the ease of the installation, and the more you change the radio in the truck, the shorter the wires will get. If you do not have the factory harness, or cannot reconnect the old one, here is the hardwire code:
Wire purpose: Truck color: Alpine harness:
Constant 12V+ Blue/Yellow Yellow Switched 12V+ Gray Red Ground Brown Black Illumination Green N/C Dimmer n/a N/C Antenna Right Front Front Speakers 6 1/2" Doors Left Front (+) Pink White Left Front (-) Purple White/Black Right Front (+) Light Green Gray Right Front (-) Blue Gray/Black Rear Speakers 6 1/2" Rear Corners Left Rear (+) Black Green Left Rear (-) Yellow Green/Black Right Rear (+) Red Purple Right Rear (-) White Purple/Black
Hope this helps!
