Greddy wiring easy question bought used w/o directions

[Styler91TSIAWD]

Red= power constant
Black=ground
Orange=?
White=?

I'm guessing white is power ignition and the brown is souposed to be hooked up to my dimmer switch. Thanks

what kind of gauge is it. if it has any kind of auto calibration, it will have to be plugged into a power source that stays on during cranking of the car. see my thread farther down for some information about it and possibly some wires that will have power during cranking, if i get any replies.
