I am going to install some off road roof lights onto my suv. I have a general idea of how to get the wires through the trucks roof by drilling a hole and using sealant, but I am wondering if there are any kits out there, or if anyone else has a better idea? 04 s10 blazer. Any input would be greatly appreciated, I am not to fond of drilling holes in my roof.

 

nwf,
I fully understand you, concerning the drilling issue !
I had thought to do the same thing, except with the two depressions at the rear of the Luggage Rack as the picture shows.
I thought to even check with GM, and see if there was some type Wiring Harness (not necessarily for an Area/Spot type lights) that I could use, but no luck there. Seems like a DIY is what I'm going to have to do as well.

 

I installed off road roof lights on my ole beater (I wish I had picrues) but it came out great. I drilled a 3/8 hole near the left side of the light bar bracket, bought a rubber grommet from my local hardware store to keep the wires from rubbing against the metal and chaffing and causing a potential short and then ran the wires, then i filled the exsisting hole in the rubber grommet and wires with a rubber type compond or RTV will work too, and its been perfect, the truck is a 1975 and I installed it in 1992, i apply a thin coat of RTV to the exsisting hole once in a wile, but after all these year its still water tight.

 

Thanks for the tips!!!
