I've decided on swapping my LB7/ZF6 from my wrecked 02 in my 85 K1500 mud truck. I'm looking for help on modifying the harness, as in which wires I'll need to connect to constant 12v source, which ones I won't need at all, etc. I'm planning on swapping the fuel tank, AC if its not too difficult, and building a custom bezel in the dash and using an Edge CTS for all my gauges. Any advice or information is appreciated.
