LSX going from NV4500 to 4L80E

Hi everyone,

I currently have an NV4500 behind my 5.3L and I have a terrible hard clutch problem since Day 1 (it about 160 lbs to press it). This week I am going to take the manual transmission out and install a 4L80E and a Transfer Case. These are coming from a 6.5L Turbo V8 from a Military Humvee. The diesel motor and NV4500 will be used for another application. My '72 C30 will end up with a 5.3L, 4L80E and a TC so later I can add a front differential and make it 4x4. Just last week I made it a dump truck :-).

All I am looking to find out is the wire harness. The ECM will be send out for programming but I need help with the existing standalone harness. What do I need to add to my harness to make it communicate with the 4L80E? I tried searching the internet with no luck.

Thanks!!
