5.3 harness
What I did was just connect my harness up to all of the sensors and accessories that I needed/wanted, then just start stripping out wire and connectors that you don't need. (usually the EGR, Air Pump, A/C, EVAL, etc), that is what I did and then told Jesse to flash my PCM with all of the deletes and add a basic tune.
You might want to get a pin out of the harness and PCM of the year that your PCM/Harness along with a wiring printout.
Thanks for the info
