Hello all -- I've been busy converting my 88 Trooper to diesel (details and links here: 4x4 wire thread ) and I'm currently involved in the wiring. I've decided to remove all the unnecessary wiring to clean the engine bay up and simplify the vehicle. I am wondering about a couple of things:

1) Does the ECU control anything other than engine management? As in, can I remove the ECU and harness and not affect any other subsystems?

2) What is the best source for a comprehensive wiring diagram for this vehicle? I've got the Haynes manual already.

Thanks.
