hi scooby newby here, has anybody got a apexi boost gauge? i,ve just bought one of ebay but it has no wiring with it just want to know if the two prong connector are both positives and do u take the earth of the bolt holding the gauge to the bracket to illuminate it, any help much appreciated.

 

The 2 pin socket for the back light has one prong for power and one for earth. Bolts on the back are purely for the clamp.

 

cheers 4 the help james, hopefully get it fitted now.
