Does anyone have the wiring diagram for the oil pressure and egt gauges? I bought these used from someone and now I dont have a clue where two of the wires go. I have the wires for the actual sensors good and I have power to gauges because they light up but Im left with two extra wires, one red and one orange from each of the gauges for a total of four wires. Any help would be greatly appreciated.

I'll look at the paperwork tommorow, but I remember twisting 2 wires together, then having to grab a switched 12v's from the radio harness. If I remember correctly, it goes

black=ground
white=illumination
red=switched 12v
orange=same as red

I'll doublecheck for you tommorow.

There is a howto in the project evo section,

areet: thank you I would appreciate it very much.
