Roof light bar wiring routing question

Hi, looking to install a curved led bar but I've been wondering how you guys are wiring them, not actual connections but wire routing.
thanks!

 

Are you asking how people are running the wire through the roof? If so I am curious to this as well.

Seems most people go down the A-pillar and behind the instrument panel.

 

Exactly!! How are people routing the wires to the inside if the truck. Not a big fan of drilling holes on the roof.

 

When I did my Jeep I just drilled a hole in the firberglass roof and used grommets and silicone but I def don't want to do that to a new truck.

 

I always assumed youd run the wire down the rubber molding along with windshield, then into the engine bay, then through the fire wall. Someone can correct me if im wrong.

 

Any pics?

 

I tried to run it that way on my truck down the windsheild as i did not want to drill but could not get it to work. So i got some black "weatherproof silicone/adhesive from homedepot. And ran it down the channel to the back of the truck along with the wires, used painters tape over night to cure. Tucked it into the rear window molding and continued down the truck and then along the frame rail back to the engine. Ill post pics once i get it back from the dealership. But you cannot even tell its there. Plus no drilling. Only downside is you will want to upsize your wireing to allow for the length.

 

I have always been curious about this as well.

This may help

How many feet of wire did you end up using. LED bars are low wattage so hoping to stay small.

 

If i had to guess off the top of my head, (i buy rolls as this is my hobby) 15' per wire(pos/neg) however many feet you need to get from the light to the rear of the truck down to the frame and back lol

Help this guy out.

 

I ended up using black windshield sealant. Put it in the channel then pressed the cable into it. Painters tape to hold it in place for a day while it set. Weather proof connector behind the hinge.

 

When I did mine I drilled really small holes in the inside edge of the windshield trim. Then just zip tied the sleeved wire bundle down that and under the bottom weatherstripping then under the hood.

That was mine was completely reversible. No permanent holes anywhere. Especially the roof.

 

Same here as some of the other guys, I surface mounted the wire to the windshield trim on the drivers side. No holes drilled! I used 3M automotive double stick tape to hold the wire down. It's been on for over a year without issue. (Tree branch hits and car washes included) the jacket on my harness wa a little lose and kinked when I first installed it. It straightened out and relaxed after a few hot sunny days.

 

Thanks guys! And what brackets are you using my plan is to install a Rigid SR-40" or a 50" midnight edition. (Already have a 30" one on the bumper)it all depends on the brackets. Was looking at the Rough Country ones that allow for the 40" bar or the relentless, caliraised that allow for a 52" bar. Still dont know if the rigids will fit.

 

The relentless ones work well, i have them on my truck. Takes a little out of ya drilling that first hole but after that its kinda like screw it drill 3 more mount the light and have a beer to settle the nerves.
I also checked with my local bodyshop to see how much it would cost to fix them before i drilled if required to fix in the future... i was quoted 300$ to drill out nutserts weld in the hole and paintmatch.

 

I like this a lot, I've been wanting to do it but was unsure of how to run the wires.

 

No drilling for wire, and it blends in fairly well. Did have to trim the rubber piece behind the hinge, but that was easy.

 

I'm preparing to mount a rigid light on my prinsu rack. I was thinking that I would run the wire along the roof rack to the back of the truck. Then go in at the cab vents in between the cab and bed. I would use about 10-12' of wire. I will let you know how it works out.

 

I don't know about the '17, but my '07 has a rubber plug on the back wall behind the storage. Easy accessibility by going under the bedside.
