Alright, I'm pretty desperate right now. Been 2 months since I've had the RB in here and it still wont start. I'm really hoping you guys can help me out. Tried facebook, Zilvia and even talking to wiring specialties themself but they always stop helping me and I ask if I wired my igniter right.

Basically, I bought a wiring specialties harness. The harness had 4 plugs that would not fit my RB20 but the 2 most important ones were the Igniter and Cas. Contacted Wiring Specialties, APPARENTLY, they told me I have a redtop RB20 but im pretty positive its a silvertop???

Anyway, I wasent going to argue with him because hes the expert. I asked him would it be fine if I wired the harness to the orignial connectors and he said yes.

My question is did I wire them up right?? I ask this because I am getting no spark and that's what is keeping this from starting. I also ask this because now I have fried 2 Ecu's. Originally when I tried to start it the ecu would be fine but now every time I switch it to ON. It will fry it immediately at pin 45 which is the black/red igniton wire which sends 12 volts. I tested all my coil packs and they're good. I am not positive on how to test my igniter.
