LIGHT BAR WIRING - 1/6/2008 5:52:27 PM

Hey All...my second post of the day requesting advice. The first go-around worked pretty good so here goes # 2. I'm building a roof rack that also has an integrated light bar and wondered the best route for the wiring...I know there are oem light bars and marker lights for the H3 and assume the wiring goes into the plastic roof edging, but where from there? Is there a hole for the wiring to get down into the vehicle? What is the procedure for removing the plastic edging on the windshield pillar?

I'd like to send the wiring through the light bar and out the bottom of it's base. It will sit in the center of the plastic roof edging just behind where the seam is for the plastic windshield pillar edging. I've included a couple photos for clarification.

Whew...Thanks for your input!

nice work!!! As far as running the wires, take the o chit handlesoff from inside teh truck and work the door trim ff...held on by some clips,from there you should see how the wires will have to run. There is a channel that you can run the wires in...if memory serves.

go to the search function and type in H3 off orad light install. 4-5 threads are there and a couple might be helpful to you. Several didn't look to have any good Post and let us know how it turns out. Nice looking rack and light bar.

I installed the SMA light bar and you do not drill thru the roof on the H3! You drill thru the plastic molding and you add a piece of metal under it for support ! Heres a link with some pics of the pieces http://www.hummerforums.com/m_115357/tm.htm as far as the wiring you remove the Molding from the wind shield and run the wire into the engine and thru one of the plugs in the firewall! No holes to drill!! I also installed the factory light bar and the wires go in the same location.

First, I don't know if this will work or not. But check out the audio/visual area on here. I was reading a post about someone switching to Sirius and the ran the wire for the antenna down beside the windshield and through the firewall where the hood release cable goes through. He put some really good pics to help. Different subject I know, but same issue (wires). Might work

Let us know.

I almost forgot don't forget to just pull the air intake cover off and you have a clear view of the engine area! Just pull up on it hard and it comes right off. Snaps right back on.

I have an '07 H3X with the chrome OEM roof rack. Has anyone thought of mounting lights on the front bar? I realize you wouldn't be able to move it anymore but that's not a problem as long as you can adjust the rear bar. The bar is hollow so the wires can be run inside the bar. Any thoughts?
