Putting a 6.0 in my 97 yukon. What would be quickest and easiest. Repinning my existing harness or just changing the whole thin. I hav a complete donor truck

Other than the A/C switch…everything else was pretty straight forward? I can switch to a 99-02 computer, I was told that the pin outs were essentially the same other than the dbw features.Its not exactly the same id have to look through my printed pinouts.
I do know the 03+ wont control ac because they require a turn on signal on the data bus when the 99-02 just needs a 12v signal just like the obs truck
Went through that mess in a astro van so ended up using a tri binary ac switch and only downfall was when compressor cycled at idle it would drop idle hard wouldnt die but didnt have the smooth transitition as if pcm could control it
That’s what I started doing as I ran thru with tape labeling everything. Just seems like the easiest route to follow.I'd personally look at the possibility of merging the 2 harnesses. I.E. swap the injector wiring, coil wiring, crank/cam sensor, and whatever else I'm forgetting into the 350 harness to minimize choppage.
