Hey all,

Ive got a bit of a project I've been working on, its a safari LWB chassis with an LS1 in it hooked up to the standard Auto trans. Has any one on here done this before them selves? Ive got a few questions and if anyone could shed some light that would be awesome. My trucks running the standard trans computer is there an easy way to tell if its 24 or 12v as I'm not sure if the guy who did the wiring before me had much of a clue and the chassis came with no plates and history to trace it? also does the tps it would have received from the the 4.2 0-5v dc (the same as the ls1) and can i just splice into the wires and run it to it as the standard holden ecu has the gearbox comp built into it? also what other sensors should i wire into the trans comp e.g. full throttle switch, gearbox speed, engine speed? if anyone has some wiring diagrams they could send me or any advice they thick would be helpful that would be awesome.

Cheers
