Here is the harness. INPUT side of amp is what connects to the factory unit and the OUTPUT side of the amp it is the one that comes from the factory harness area. As I said, after doing these runs, installation is easy. I had a total of 2 hours of installation time after making this harness. If you are using a KEY, you do not need to connect a signal wire, but you will need to press the radio’s detect button. Again, the best mod, after you’ve changed all the speakers because they blow the factory ones.
