I'm not wanting to run the msd 8877 connector harness, I'd rather just spice into my engine harness. I am trying to figure out where the two wires from the coil go so I can splice this in. I want to do it under my dash and not have to run wires all the way out to the coil since I have everything on my engine wire tucked.

Does the two wires run to the pcm, icm, connectors under dash or where? I got my pcm under the dash along with the hyfire VI under the dash.

Being that my oil is mounted behind my alternator and hard to get to and my harness is completely tucked and wrapped I can't even see the stock colors of the coil wires. Anybody have the color of them also?

This is on a single connector coil(1996 car).
