You wouldn't be testing at the Coil. You'd be testing to two wires in question. Testing will tell you which one plugs into which part of the coil... since you don't know.It had the module but it was bad, po replaced with a msd ready to run dist and coil. I don't understand what testing at coil will do for me. I have a new dist going in with purple and orange wire with standard ford plug. Coming out is msd ready to run with red and orange straight to coil.
It's an 82 it was always carbed.
