Can anyone tell me which color wires should I wire my boost gauge to? What color for positive and negative?
Thanks

 

most boost guages just use a vacume line and any wires would be for lighting if you have an electric one it probably requires some sort of sending unit for a decent anwser you need to say what model your guage so someone with a similar one can chime in

 

put your positive into your lighting fuse slot. i think its a 15amp. and then bolt the negative to something metal on the car.

 

what color wires? for the positive negative

 

Red is positive Black is negative
