I am about to hardwire my vpc and I just wanted someone to tell me I have the right idea here. All I have to do is tap the 4 wires (yellow, white, black, and red) from the vpc to the stock harness and put a 1200 ohm resistor in the mass connector right? That all I have to do according to vpc install It just seems like there are quite a few wires left in the vpc harness that are unused in this application. Just double checking. TIA
