Anybody ever use one of these gauges from big mark design? I need some help wiring up the oil pressure light. There are two wires that I found that looks like it hooks up to the light. The problem with these 2 wires is that they are labeled ground on them. One is red and the other black. There is also an orange wire that is labeled pressure. I have the pressure gauge wired and I have the oil temp wired. I also have the volts wired and the fuel wired up. Anybody have any ideas on wiring the oil pressure light??

Thanks,

That's a nice combo gauge.

IIRC the oil idiot light has power to it, the other connector goes to the pressure switch. The switch is the ground.

Am out of town for a few days, buttwill look when I return.

Sorry about the delay. Black goes to green with black trace. Red goes to red coming out of the pressure guage
