Wiring harness question
Noticing some issues with the harness on the 03 Savana 6.0l harness. I have an 01 Silverado 4.8l parts truck. Can I use that harness for my swap? Both are drive by cable. The truck was 4wd with the4l60e and the van is 2wd 4l80e.

Re: Wiring harness question
I’ve heard the van harness gives you more wire length...may help with pcm mounting.

Re: Wiring harness question
The main "leg" of the van harness has a good deal of extra length (like 14-18" IIRC). My donor was from a truck, and I had my harness done on the van-donor style. Made moving ECM mounting locations easier imo.

Re: Wiring harness question
My van harness has sensor wires cut out, multiple butt splices crimped on, to include mystery wires added.
