Starting my swap project in a couple of weeks into a non-computerized vehicle and I need someone to tell me what computers I will need.

The engine is a Duramax LMM, trans will most likely be a 4L85E built to take the abuse. Street only vehicle, 4200lbs, rwd, emphasis will be on MPG.

I realize I will need the ECM (truck), TCM (LMM Duramax Van), and gas peddle (LMM powered donor). What else do I need to make all the wiring work?
