I am trying to connect a J&S Safeguard system my ride. However I am having troubles locating the correct wire and pin out on the ECU connector for Ignition coil 1.
I have wiring diagrams from GM and details from a service manual, I have been able to locate Ignition coil control wires from 2 to 8 and the 2 knock sensor control wires. However I am missing something as I can not locate and details that will show me which pin and or wire is for Ignition Coil control 1.
Any help would be great....Greg B. maybe
