Hey guys, new to the forum here. This is my first post so please bear with me. Alright so I picked up a complete 5.3/4L60e combo out of a '04 Trailblazer. It's DBW and included the TAC module and pedal, all accessories, wiring harness, fuse block, and exhaust. I will be swapping this into a 98 Tahoe. I just finished re-pinning the Tahoe harness for the 0411 computer. What I'm wondering is when I swap the 5.3 in will I be able to just hook up the '04 computer to the existing wiring? Or will I have to swap some pins? I plan on using the original Tahoe harness and just adding in wires where they're needed for sensors. Any help is appreciated guys. I plan on documenting this swap and sharing info on what I had to do to make the swap work. Also I swapped some seats from an '03 truck into my Tahoe and I plan on sharing info on that.
