How to Wire Roof Rack Lights

What is The Best Way to Wire Roof Rack Lights?

Before you proceed with any installation, ensure your lightbar is securely mounted to your roof rack. Over time, corrugations can severely damage lightbar mounts made of cheap or flimsy materials. Lightbar mounts that attach directly to sheet metal can sometimes fatigue the metal around them and break. It depends on how the lightbar mounts.

It’s time to wire up your lightbar after mounting it on your roof rack. In addition to wiring the lights, you must run the wires correctly. Wait to cut a 20mm hole in your roof skin – you have a few options. Cables are typically run behind snorkels using stick-on cable clips.

The wiring from the roof is not usually a plug-and-play affair, and you will need some auto-electrical knowledge to select a suitable wire gauge and join or terminate the wires since an extended wiring harness is necessary in addition to the supplied wiring harness.

Here Are The Steps for Wiring Roof Rack Lights

Step 1. Side glass of the Windshield

Vehicles with windscreens that do not allow this position depend entirely on the vehicle. It is usually a twin-core heavy gauge wiring from any 12v supplier that runs from the light to the power supply. We will place the wiring on the side of the windscreen and secure it with silicone adhesive.

Step 2. Down the Back of the Cab

However, it is an acceptable option that generally only requires cable ties for installation and requires a much longer lineal meter run. A ute’s cabling is generally routed across the sports bar or headboard of the tray and down to the chassis rail, attached to the roof rack or roof rail.

Step 3. Wire Goes Down the Snorkel

Despite not being common practice, you can loop the wire from a light roof bar into the snorkel head. It is necessary to drill a hole in the airbox side of the engine bay for the cables to connect to the engine bay. A river crossing will require a complete seal and testing of the penetration through the airbox.

Step 4. Drill Through the Roof

It is not reversible, making it the least desirable option. Wires are fed down into the vehicle cavity through a rubber grommet through a hole drilled through the outer roof skin.

It would help if you only used these options as a guide. In case you are still unsure, you should consult with a qualified auto electrician or 4×4 shop about the intricacies of the installation process and correct wire gauge selection.
