Finished up 90% of the harness tear down. I still have the trans harness I left mostly intact because I couldn’t figure out how to separate the blue connector as it was slightly different than the other black j1 and gray j2. Since I didn’t remove this harness and I don’t have an 08+ to look at I’m going to have to figure out which sensors are which and what I can completely eliminate. For those that have done a gen 4 ls swap did you run new grounds or keep that one large ground harness intact?
