reverse indiglos on a 98 accord

does anyone know or have a link that can help me put in reverse indiglo gauges on a 98 accord? I can get the gauge cluster off and getting the gauges on isn't a problem but i don't know anything about the wiring. im not sure if im supposed to wire the gauges to my headlights or the dimmer, and i dont know where any of the headlight or dimmer wires are. theres also three wires coming out of the gauges to connect to the inverter but theres four connector wires coming out of the inverter so i dont know what the extra wire's for either. any help is appreciated.

Hope this will help ya
