The true you don't use your serria wire harness if you get from psi. Pull Harness out from the fire wall on the passenger side its a bitch now get a heat gun n it be easier.unhook the four connection under. The dash where your serria pcm is and unbolt the thing that wired going through. And don't cut nothing. All you need alternator red wire battery starter wires and the fat pick wire that hooks to you factory coil.that's all I can think of right now if I can think of some else I let you know
