thanks for that mate.
i will have a crack at it and see what hapens.
the red wire is live.
the black is the ground.
the gray is the ecu.
so on the boost gauge thare is a red,black and orange wires.is the orange the constent live.
hmm.. which ones you have? the one that changes colors?
Thats the only thing id imagine its for mate, id say the orange is there for the light tbh. you leave it wired with just the black and red wires the light will be constantly on, where as if you wire the orange to a light source eg: sidelight, it will only come on when your lights are switched on.
Ahem.
