Default Re: How to wire light bar

DAMN, you have a ton of work on your hands with all those lights! They will not all fit down one A pillar on the outside. You will have to split them!

or you may want to look into running them to a block that you can attach to the roof rail, than run two wires into your engine bay. Not sure how that would be done though.


When I wired the GOBI racks lighting in, I had 6 total lights/ 12 wires total. 6 wires down each a pillar. I used wire that was very flat and each postive/ negative wire were together. That helped and I did have to tape the wires under the pillar all the way down OR you get rattling at highway speeds from those wires. ALSO, make sure to leave slack so that when you have a windshield change, they can be moved to the side. I would do a quick disconnect and attach to that lightbar. This way if you ever have to get the bar off for some reason, you can remove the bar without cutting wires. Safest place for that would be just inside the engine bay on each side OR back up by the roof rail. Engine bay would have a cleaner look and you can disconnect that way for windshield changed also. I used heat shrink tape on all connections and loom over all wire in the engine bay. Switch wires were pulled through the firewall. I made my own hole and seales with JB weld on the inside and in engine bay. You can insulate teh hole with a rubber grommit. I did that hole for the switch wires and through the market light hole for teh CB cable. Much cleaner than RTV, but much more perminant as teh JB weld is like steel when it's completed.
