5.3 Truck Harness Compatible with LS1 Engine? I'm wondering what kind of harnesses are compatible with the sensors on the LS1 engine and PCM?

....either get one custom built for your setup or find a harness off another engine of the same model & year. There are subtle differences as to what's going into the pcm 80 pin cnntrs back from the sensors....in my case it was the Oil pressure sending unit, AC compressor cnntrs, and the DBW TB system...I ended up just repairing the original one (looks like crap but it works) .
