Hello,

I'm trying to wire 52mm Greddy electronic boost and water temp. I understand that red is 12V constant, orange 12V switched power, white light source, and black ground. I do not have any idea where to connect the 12V constant (red wire)... does anyone know???

ps im connecting orange to black wire on cigarette lighter, white to ash tray light, and black to ground

You can wire it to the headlight circuit.

i honestly have no idea what or where the headlight circuit is. could you explain?

and wouldn't that be a wrong place to put the 12V constant, since the headlights aren't constantly on??

Might want to tap into the radio wiring - there's 12v constant coming to the radio.

^^ yeah, pretty much the radio wiring is best for electric gauges, thats how i did mine..

i just put in an aftermarket stereo and it's already locked shut in there. is there any other place to connect the 12V constant?

^^so unshut it LOL

nah, radio would be best but if you really dont want to put it through there, you can put it through your cig lighter since it gets 12v when you put the key to acc/on position..

They aren't constantly on but they constantly have power.

i connected my apexi boost gauge to my dimmer circuit(switch) this way i can adjust the brightness. you can find a constant power source by using a test light. there are a few by the ignition switch. use vampire connectors instead of cutting the wires. they clamp on over the existing wire, only breaking the outer insulator of the wire.

This is where I hook up my gauges. It's called the reastat, now that is a clean install .
