Does anyone know the correct wiring arrangement for the ignition coil?
I am having difficulty find the correct wiring diagrams for 1986 sierra, this was the year when every was switched over so the diagrams change!
Anyway as far as I can tell, the ignition coil centre terminal is connected to the distributor cap
I am then left with the black push on terminal (with an additional plug in component that is connected to the mounting bracket screw) and 2 Nr green wires.
Logic says that the black is the negative (-), but Dogwoods diagram contradicts this!
Can anyone help or have photos ???
