I tried to install my head unit last night (Alpine 9857), and got all the wires hooked up to their respective color on the harness. When I put the key in, everything powers up and worked fine, but when I try to start my car, it will just click, and not start. A few of the wires didn't seem the same size on both the harness and the deck (such as black and red). Any ideas?
