I bought a 6.0 swap for another project and got everything computer harness gas peddle 4l80e EVERYTHING lol my question is will the 6.0 harness work in my truck so I don't have to repin for the transmission? Or do I just need to repin the 4.8 harness and segment swap?

I would just use stock wiring and get the 60 to 80 Pigtail adapter to match your 80. Sell that other harness you have with pedal in the classified section to recover your cost on said adapter.

Here it is http://www.speartech.com/ProductDetails.asp?ProductCode=4L80Eupgrade

You can try to save some cash and use the other harness but IMO thats alot of work and you might run into bigger problems $150 cant solve.
