Ok I solved all this. For the PNP switch I ran B pin to new PCM, wire A isn't there form factory.
As far as the TCC wire I'm just an idiot. The purple wire won't get power unless the ING is on. Dur, but I can't be the first to do that!
Still no PRNDl light tho.

i found out where the wires were run for the original harness by looking at the diagrams. idk how running the green wire to the pcm works for you as it seems they all go thru a fuse or relay but you have a custom harness so it may be different than mine as im using the fuse block that came with the escalade harness. but heres my revised diagram for the pinouts for the 03 harness. may or may not help you but here you go
ok so idk if you got it figured out. but like i said i was gonna confirm the wires and i did. all i had to change was the light green wire going to the reverse lights. everything else stays the same. BUT i am using the original harness, pcm, and fuse box. so our setups are a lil different. at this point im not sure if my gear indicator light will light up. i havnt checked that part out. i will try and confirm that in the next few days. but i just wanted to say that the round connector matched up perfect (no re-pinning), same for the 4 wire connector pnp, and same for 6 wire pnp with the exception of the reverse lights. like i said, just take the new gray wire and hook it to the old light green going to the lights and you should be good on that part. hope that helps. let me know
oh and btw, i gave the link to my thread to my pops to read through my conversion process and he told me he really liked your truck. as do i. props man. really wish i could lay frame.
Thanks man! Just remember to run a ls1 oil pan for laying frame. I ran the hotrod pan, per advise on here and it's too low.
