Question Harness Help....1st attempt!

Hey y'all! Been working on a 2003 Tahoe/C-K harness to make it Standalone. I have questions about that scope outside the 2002 harness re-work on LT1Swap, because his process goes through a 2002 harness without a TAC Module. Not sure about a few wires on the trans too. Any help is appreciate, I am in way over my head on a first swap an no prior experience. I'm close, but no pals to feed beers to for hands on guidance locally!

So:
1) I have 2 Pinks on the Range Sensor, pins C - Ign 1, and E - Starter Relay. Do I need both?

2)Looks ok to remove the LtGrn-ParkNPark, DkGrn-ParkNStart, and Gray-Trailer Brake Lights from the Range Sensor plug. Is that correct?

3) Do I need both Pinks on the Trans Plug, E-Fuse Output Run Crank, and N-Trans Pressure Switch Signal

4) It looks safe to remove the LightBlu- CHM Stop Lamp voltage from the TAC connector plug too. Is that correct?

1 and 2, if you're not using the range sensor for back up lights or as a neutral safety switch then you don't need them. 3 Dont remove any wires from the trans plug! And 4, you need to hook up to the brake switch, the wire that is hot when brakes are applied.

Not sure if it helps, but I don't even have that range sensor wiring in my harness, at all. The harness was built without it, but it doesn't contain "need to run" functions, just so were clear.
