Coil pack wiring Q How do I tell which of the plugs is for example for cylinder 1? There are no markings on the wiring and I was not able to find any wiring diagram with colors / codes.
I am doing a carbed LM7 and have bought the coil pack wiring (2 wires with one big plug and 4 small ones) new from GM.
Help me out, thanks!

TTT i have the same question, im relocating my coil packs how do i tell which is #1 and #7 i have them mounted in the new brackets. i guess if one way doesnt work there is only 1 other option ( back wards ) but, is there a better way to determine the which coil pack goes to which plug? markings on harnes? or pins on connector?

Cylinder #8 = Purple
This is off of a 2000 TA but should still be the same layout
Check out this lay out to yours.

I've relocated my coils and now run billit valve covers. I marked each connector with marker from the cylinder it came from, but this thread may come in handy one day.

I know this is 5 years old but thank God for this search button! I had mine backwards on the passenger side on my reinstall and couldn't figure what was wrong with it
