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:

The wiring harness should come with the bar. I bought that same light bar and the harness came with it ready to install.
Having said that, I had to hardwire it because that harness is only for 2006 and up (lucky you)

Re: OEM LIGHT BAR?.WIRING hook up
That's great. Does the wiring harness include the toggle switch, and wiring that goes to the toggle switch also?
Can you give me the GM part # for this light bar please? Much appreciated....

Mine came with it.
Sorry, don't have it. It's been almost 2 years. Call the dealer, they'll tell you.
