what did you learn about the wiring? i just started tearing into the truck harness to see what i have to keep & what has to be removed.
i had to get a harness from pull a part since i sold mine with my motor so his swap would be all plug & play for him. little did i realize at the time i was still going to need part of my harness.

basically the guy i talk to told me what pins to remove from the obs pcm and plug it straight into the ls pcm. makes for a really easy install without having to splice tomany wires.i have all the info scattered over a few emails. once i get it all compiled together ill make a thread. ill try to do it today.

If it takes an impact you are doing it wrong. The pulley has a flange on it the same diam as the bolt hole. Dont push on it thinking you are pushing on the crank. I put a 3/8 extension in the bolthole and then push against it.
