Greddy boost gauge wiring question


Registered User
I bought Greddy boost gauge with build in voltmeter.
I have little trouble with the wiring.
I want to wire it to headlight switch to be able to turn on the gauge when turn on the headlights. Also i want to be able to dim the gauge light.
I removed the headlight switch.
There are 4 wires coming from the gauge
Red - constant 12v. I guess this goes to the red wire on headlight switch.
Black- goes to brown
Yellow - Ignition line. This goes to yellow with red stripe?
White - Parking light line. I have no idea where this wire goes. I guess it's the 12v wire for the lights of the gauge. (Grey with blue stripe maybe)?
If anyone can tell me gauge to headlight switch color to color wiring I would be really grateful!
