Sounds like the way I've always wired them and not had any problems. Did the car shut off before you installed the MSD box?

Yes it shut off.I,ve replaced the harness from the block also,with a good one froma 66 Cuda.The last one was spliced and cut and burnt at the block when I got the car,so I,ve replaced it and took out the ecu to add the MSD 6AL box.Fishy68.did you do the bypass?
