Wiring diagram of truck transmission shift range thingy

Looking for the wiring diagram of the transmission shift range thingy (black box on the outside of a 4L60E in trucks) for an early 2000's Silverado (512K LS1B, 2000 - 2002 would work). Doing a swap and the shifter in the car does not have provisions for the P/N switch. I believe that I can use a couple pins off the shift range sensor (or whatever it's called) to accomplish this same function. The PCM has already been flashed as a Camaro, so I don't need all the functions that are usual connected when the transmission is in a truck.
