Can anyone explain to me how to wire the key switch ignition to get the engine to start?
Running a MSD Ignition and the car spins over but no spark, I cut a wire or 2 and cant seem to find where the cut is.
I need to get the car running.
MSD is wired correctly.

I have a 2 wire into 1 from the key switch but one black wire is cut.
I have no idea where it goes to.
I suppose I need wires going to the starter relay on the engine side firewall somewhere. I hope someone can explain it in simple form. I'm not very electrical savvy. Thanks
