How to wire a roof mounted light bar.

The best way to do this is to drill a new hole in your roof near your roof mount brackets and run the wiring down directly into the cab of the truck. By the way i like the location on the rear because it is easy to run the wire up to the roof by just dropping the rear section of the headliner. I had a 30 inch across the hood. Take the red wire of the light and join it with the red wire of the switch.

Make a connection between the light and the relay switch. The rest of the holes i had welded up. Also like you stated height becomes an issue when in the garage. The switch will maintain the flow of current on the light bars.

I go though every step so. This is the best method because it is the shortest distance for the wire to travel and it has the least chance of getting smashed in your door jamb. Also roof mounted bars can have a tendency to cause glare on full windshields. Once it is in the snorkel head the cable will run down into the dirty side of the airbox and will require drilling through the side of the airbox to penetrate the wiring back into the engine bay.

This was my midsize. Now comes the critical part. We choose the nilight 52 300w spot and flood combination led light bar because it has both spot and flood lenses in one bar was affordable and had decent reviews on amazon. When having the roof rack installed we added a front 3 slat cross member so that we could mount a light bar it was a 65 addition.

After installing my a pillar mounted police light i m fully aware of just how full the a pillars are. Although not commonly adopted it is possible to loop the wire from a roof light bar into the back of the snorkel head. I think they are to high and will get caught on trees and what not and get damaged. I m not a fan at all of the roof mounted light bars.

For safety purpose wrap the soldering portion with electrical tape. Of course using that type of wire gives you 3 wires so i paired up a couple of glands on the rear of the roof where the port installed roof rack went.
