Re: OEM LIGHT BAR?.WIRING hook up
Do a wiring search and You will find allot of help. But, 3 wires has to do with power, grd., and switch to control relays that turn the actual power on to lamps, I think. It has been a long time since I looked and lost allot of brains cells over last year or actually My girls tell me it is since i turned 50 in October.

Re: OEM LIGHT BAR?.WIRING hook up
Trust me i have been searching, I found out red powers 2 of the lights and purple powers the other 2? dont know why? maybe they draw to much for 1 circuit? I have been reading people adding relays, I dont know what they do and if i need 1?

Definatly run A relay, It takes the load off the switch. A relay is used to power the circuit, the switch just has to turn on the relay therefore taking the load off the switch. Heres the oem diagram.

Re: OEM LIGHT BAR?.WIRING hook up
Anyone have part #s for the 2 wiring harnesses that you need on an 2006 H2 to hook up a low profile light bar from a Special Edition H2?
This is the lightbar I would like to add:
