This 95 is a project that I'm working on for another member on here. It started life as a 350TBI/4L60e and I'm swapping in an LQ4/4L60e. Trans will be updated with the Gen III/IV style 4L60. Using a Nelson Performance Harness, Transdapt Adapter Plates, and everything else needed for a Smog Legal Setup. I'll go into detail with the swap and take pics along the way.

Made a little progress, haven't had the chance to post up yet, but here ya go... I removed the old wiring harness for now until I figure out what needs to be removed and what needs to stay. I also pulled the engine back out to change the oil pan gasket and bolt on the pickup tube and windage tray. Also had to modify the TransDapt Adapter bolts so that they would tighten all the way and not hit the block itself. After that it was time to drop the engine back in and figure out this wiring mess...
Pulled the pan off, took a quick look at the bottom end... looks pretty good

Which nelson harness did you buy and at what price? I swapped an 03 6.0l/4l80 into my 95 extss grafting the 03 harness to the 95. Way too many wires as I did not remove the unnecessary ones. I'd like to clean things up and have considered starting fresh with a new harness.
