I'm new to this forum but I've had some luck finding other answers on here but currently I'm stuck on my 97 k3500 wiring harness, I've managed to find wiring diagrams for the transmission but not the actual switch connection to the neutral safety switch, every post I see gives me wires that I don't have like for some reason the starter relay wire should be a yellow but in my case it's black and there's 2 different greens I'm stumped please help!!
