Ive been having problems with the sensors down the intake side of the engine (EB 4.0MPEFI), the wiring looks dodgy. I want to test the wiring loom, which plugs in not far from the MAp sensor,
and runs through to the injectors, throttle body, ECT etc. I have a spare loom, Im thinking of
unplugging the loom, plugging my spare loom in, and with the ignition on, test the voltage/resistance
or whatever is needed.
AANyone know if this will work, will it stuff up my ECU settings?
And, obviously I'd have to find out what the readings should be for each connection, I'd find
this in the manual, wouldn't I?

Thanx if anyone can shed some light as to how this would work, if it will.
