Wiring does not match the diagrams

Hi

I have a secondhand Go EFI 300002

The previous owner assures me it was running fine before removal

The loom was cut just after the fuses. The problem I have is that the wiring doesn't match the diagrams.

I have a small red wire with a fuse, fat yellow wire with fuse, fat orange wire with fuse and small blue, white, yellow, black.

It works ok when I connect red and fat yellow to Bat, blue to ign -ve, white to ignition on but thats nothing like the instructions. Do the wires change colours at the connector ?

HELP

Did you ever get any answers?  I'm trying to figure out what the small red wire with the 15amp fuse is for.

I am away from home, when I wired mine some time back there was something amiss with the drawing that I can't remember, but I am sure red with fuse is permanent power to keep the memory in the icu, goes direct to battery.

With my answer above, it is a thick red that goes to battery, it depends on what system you have, a thin red may be a/c, to signal when it turns on.

Thanks ajax I really appreciate you taking the time to reply.  I did see elsewhere that the thin red wire is the a/c signal wire so that confirms what you said.   I'm chasing a stalling & no-start issue on my dad's dual-quad setup and I'm beginning to think that he did not wire it correctly and/or there is a grounding issue.   I'll be digging into it more on Monday but I just wanted to say thanks again!
