Got a few questions while reading, I did not see an answer too and I realize that most use a stock harness to run the new LS engine.


However, I'm going to run a standalone harness that's already been modified by LSPerformanceWiring. So, my question is, out of the stock harness (that was modified for TPI 7 years ago), what wires do I need to keep in the main harness and what wires can I remove? I know I can remove all the ECM stuff but I probably need to keep the hot wires and starter wires??


Also, anybody running the Schonfield 1 7/8" headers? Any fitment issues? Is there ceramic coating good quality?


Engine mounts, is everyone running the stock clamp shell bolted to a Dirty Dingo or other plate that is set back 1" or what is better?
