    There is going to be a bit of wiring work no matter how you do it. There are a few websites with detailed step by step methods for making a harness into a standalone setup. I've done a few but didn't document anything since it was just for me. I've written a ton of detailed instructions for the swaps but never for harness modification. The good thing is you can use the existing fuse block on most swaps though I've never done a 1994+ model.

    quick question Im neck deep in doing my ls1 into 240 swap right now. But after i want to tackle a 5.3 swap into my 92 2 door yukon. as I understand it i need the 5.3 and 4l60e b/c my old 92 tranny will not work right correct? and if i swap the newer 5.3 with tranny in will i have to do any other type of conversions to make the new tranny work? new drive shafts? etc? i want to keep it 4x4. I havent found much that touches on this
