Check out LS1tech.com forums under the conversions page for a ton of great info about swapping these motors in to just about anything. Most of the info is applicable no matter what the motor is going into. LT1Swap.com has all of the motor side wiring stuff you need to know for modifying the stock chevy harness. There is also a thread on pirate that is titled 5.3 swaps, but the info also applies for all gen3/gen4 gm v8 motors. I'm still in the middle of working on mine, but between those sites and asking questions of people that have already done it, I've pretty much got it all figured out. Now I just have to figure out how to make time to work on it
