I'm almost done with my swap I just need to finish some wiring which is what brings me to the forum. I used the original wiring harness and fuse block for the trans and engine (LM7) from the 2000 suburban that my power train was pulled from. I've got the majority of wires spliced up to make it work and it runs good in the Sierra. I have concerns with the transmission wiring since an electronic auto is a new can of worms for me. So far, I have got the TCC wire spliced in, and the Pink wire I believe from pin C on C100 wired to a fused keyed 12v to power the trans solenoids. What else needs to be wired up to make the trans work? I don't want to leave out a wire that needed to be hooked up and mess up the trans.
(I do know about lt1swap.com)
TIA!
