Hoping to get my Optishift trans controller installed on the truck soon, but i'd like some advice from the guys that have done it. I know most guys here run a PCS, but this should be pretty much identical. Mainly looking for the best place and method to tap into the factory wires. I want to do it cleanly in case i remove the controller down the road. I'm also wanting to use my cruise control buttons for the manual shift like a couple guys here have done. I'm sure this is pretty simple, but i HATE wiring and i hate modding a factory harness.
From what i've gathered on their this is a list of wires i need to tap into:
Keyed 12v power
PCM ground
TPS input to the PCM
VSS+ wire between PSOM and PCM.
2 wires at the PRDNL switch for range selection
Blue/Black wire in the steering column for cruise control
