Greddy oil pressure gauge

[jakethesnake]

im in the process of installing my greddy oil pressure gauge and in not sure what i should wire up my gauge wiring to... i have black,white,red, and orange wires

black = ground
white = light
red = oil pressure read
orange = ?? ??

what do i hook all those wires up to?

i am not 100% sure but orange maybe dimmer?

on my greddy gauges

black- ground
white- lights
red - 12v
orange - accessory "ignition"

so whta do i tap all those wires to?? i know that black is just a ground but what about the other ones?

well i'm not sure about your specific gauge, but going off of what VAs13 said:

red-constant 12v power (on all the time)
orange-ignition (meaning only turns on when you turn your car on)
white-lights (to a wire that's on the dimmer, so it the gauge dims with ur dash lights)

get a volt meter and go in the radio harness.

for illumination its the - red/blue wire that comes off of a plug
12v - use a volt meter
accessory"ignition" - volt meter behind radio

so would i have to plug up the wire that dims my gauge because i dont care to have it dip, i just want it on when i turn my lights on at night

[96Turbo]

yea, you want it wired in with your dash lighting (ie dimmer). The only other option is wire it to something that comes on with the car (ie ignition) and have the gauge light on all the time. I would just wire it in with your dash lighting. It isn't that hard

[w0nderbr3ad]

go in with a multimeter and turn your lights on and off and test where you get 12v with the lights on and thats where you tap into for your illumination (white wire).

i found a diagram and this is what it said...

Red- 12V source
Orange- Ignition line
White- Parking Light Line
Black- ground
