It's possible he just disagreed with some part of the process you mentioned, not that you're using GM stuff. Or maybe he just didn't agree that it pertained to the original question in this thread. All my wiring and connectors are more GM than Mopar because it just worked better. Yeah I said it. The Mopar wiring was ****. I use Ford and GM parts throughout my ride if it works better and costs less. Hell I'm putting a GM overdrive transmission in my car this winter. Who cares? Only the purists. Build your ride like you want and forget the rest.
