Didn't know where to actually put this but here.
 

Doing a 5.3 swap into my bird, I have the Lm7 ( 5.3 ) harness (auto) and need to know if I can convert it to a T56? I know off the top of my head it will need reverse lockout/speed sensor? and reverse lights?

Does anyone know/have done this before know what pins or what I would need to wire or could possibly point me in the right direction to a schematic?

Thanks a ton!
