I'm looking to do the COP conversion in the near future and I had a few questions. I have an engine harness from a 1998 Mark VIII that I had for another project (my old 4v swapped 98 GT) and I was wondering what the differences were between my 98 Cobra and the 98 Mark VIII (other than the Marks had the COPS)? Can I take out the 98 Cobra harness and swap in the 98 Mark VIII harness so I can run the COPS without any issues?
