I'm waist deep in my swap, and I have a few questions about my TBI engine harness.

I'm swapping a 2003 DBC LQ4 into my 89 k1500 5 speed. So far I have deleted A/C, evap, and cruise. From what I understand, I will not need The TBI ECM for anything. However, there are a bunch of body power wires, hvac wires and gauge wires spliced into the TBI engine harness. Do I just need to seperate these wires, and hack all of the actual engine wiring from the harness? I'm going to try to tidy up the engine bay the best I can, without removing necessary wiring.

As always, your input is appreciated.
