.orange Wire not inserted in the green connector
There was an orange wire that never had a connector pin installed on it and the wire was not inserted into the green connector. No documentaton as to where the other end of the orange wire went, so I dont even know what was not going to work when I installed the harness. I sent the harness back for a refund I can get this kind of sloppy quality control for half as much.

good for swaps
loomed nice and will work on most ls swaps. did have to add a couple wires for my uses. instructions are vague but if you know your way around wiring it works

Works-ish.
Instructions are a copy of a copy of a copy… written by a competing vendor (PSI). I tried calling PSI for assistance and they informed me that someone online as stolen their instructions. Next time, I will purchase a PSI or Painless harness.I did have some grounding issues…. Ended up running another ground wire and everything started to work.Also, if it’s a gen3 LS, you will most likely need to change O2 sensors. Had to hire a tuner to help me figure out a couple things as the directions are not the greatest.
