hey baic..ive searched the boards but cant find anything. im switching from an autometer boost gauge [mech] to a prosport gauge [mech] and the wiring is confusing me. the autometer only had 2 wires for lighting [black/white] and the prosport has 4. [black/white/red/green] the prosport has an opening ceremony and is suppose to be white during the day and green and night.

 

that's the problem with getting cheap Prosports, u get what u pay for. While it may look nice and all, it's almost made entirely out of plastic, plus their instructions are confusing as hell. All generic pictures with no words.

 

red is obviously battery + black is battery - i would say green is going to the healight switch and the white could be a switched power source? just guessing here but it seems logical without looking at the instructions myself.
