OK can anyone explain these boost gauge installation instructions in simple brain dead terms for me as I'm not to "switched on" (excuse the pun) when it comes to understanding wiring diagrams, and also the best circuit to tap into i.e: the courtesy light, etc on a sapph, & would it need to be fused.

CHEERS if you can help!

 

What gauge is it m8y? Cant see why you need so many electrical connections.

 

It's made by Auto Gauge, with the different light color backgrounds thats probably why its got extra wires?

 

ok well the vacuum hose is easy. That connects to one of the outlets on the back of the inlet manifold.

Black goes to earth (brown on ford wiring)
Purple goes to dash lights (grey with yellow stripe on ford wiring)

The others Im not 100% sure on but it looks like Yellow goes to perminant live (red on ford wiring) and the orange to a switched ignition live (yellow on ford wiring)

I would advise cutting into a circuit that can be easily removed without messing upt he original wiring.

What Ive done on mine is I've tapped into the ISO connector lead that converts the standard ford headunit wiring to ISO (for use in connecting any new stereo) that way I havent cut into the original ford loom.

 

CHEERS for the top advice I will tackle it between now and sunday, all seems a lot clearer now!

 

the yellow and orange are wired to the dimmer control on the dash, so that if you dim the dash lights the gauge light will also dim to match. dont think the rs turbo's have this
