LET loom, wiring ID

I have been fixing up my LET loom today before its installed, basically a few plugs had knackered wiring around them. So I replaced them, also made the loom a lot tidier.

I have found 4 wires poking out of the end of the loom (where the BLACK ign+ feed comes out).

They are all small gauge wires:
Brown
Brown w/red
Black w/yellow
white w/black

Can anyone tell me what these wires do?

Cheers :beer:

John.

Cool, will wire that into a toggle switch on the dash for low boost wet conditions (going in a Nova remember).

Any gen on the Brown w/red

RDS: The ign feed wire is solid black and is a lot thicker gauge.

Brown = ground for 1st gear switch
Brown w/red = 1st gear switch
Black w/yellow }
white w/black } Reverse adpator loom for reverse gear switch.


Normally the brown and brown/red are reverse light switches, but when working on my mates LET the reverse was the black/ yello/ white ones. Was well confusing.

Ahh yes I see, so one switch for 1st gear ident tells the ECU to go on a lower boost setting and the same for reverse gear?
