Default Light Bar wiring

Anyone used a 4wdsupacentre wiring harness for light bar?

Have it all hooked up, no go. Light bar does power on if wired directly but not through the headlight loom.

Any suggestions?

Forgot to mention.. read about negative & positive switched and found a lot of conflicting info.

Think this could be the problem?

You only need the trigger for the relay to go to the high beam hot wire, that's it, then it will turn on and off with high beam

Yeh im using one from 4wd superstore. Works fine. I hook it up to my fog lights. Obviously i need to turn my fog lights on in order to fire up the lightbar switch.

I did change the H4 plugs it came with to suit one I created for the fog lamps.

I wasnt keen to hook it up to my high beams as I usually use thr auto hi-beams options.

How do you have it hooked up? Its very straighy forward, what did you hook up the H4 connector to? My jeep is HID so it doesnt use H4, hence I tapped into the fog lamps.

Check the arrangement of the red, white and black wires on the switch if you haven't done so already.

I recently installed the dual 7" spotties with 4WDsupacentre harness and had the same issue, nothing coming on. Re-arranged the switch and all good now.
