I hooked up the 88 spark box where the old one was on the starions harness. It was pretty easy to do Color to Color. As for this wire your saying to be pulled from the ecu I have not attempted. I found in the turbo Bible people here where using the stock monty coil wires to get there power Which I did and found 12V when I tune on the key.
I will search for it as you said to do. maybe going to the ecu is my ticket.
