'01 5.3l with tranny and transfercase dropped into a 99 tahoe
Hvae a painless wiring harness - most of it is installed now
Have the computer flashed already

My next question is the new harness hass no connections going to the transfer case. so im assuming that i will be using the original wires from the old harness because the switches for it are in the cab and dont go through the new computer,,, is this correct?
