Hello guys,

I need some advice on light bar wiring.

I mounted (2) 6" led light bars, and installed a wiring harness.

I want it to come on with fog lights, and control with a switch that was provided.

I mounted the relay, attached power to battery, attached ground, attached light bar wires to relay, and my confusion comes from splicing in wiring to fog light power wire.

Where do I find this? Do I simply attach the 3rd switch wire to one of the two wires that go into a fog light?

Any advice would be appreciated I am stumped on this one.

Thanks

 

Take the power lead you hooked to the battery off and splice that inton the fog light hot wire.

 

I thought you were supposed to power the lights directly from the battery?

Because even if I do that I still have the switch wiring to deal with.

 

Attached is a wiring diagram that might help. Substitute the colors shown with your own. It shows how to wire auxiliary lights to both a switch and another trigger, like reverse lights or for lights. This diagram works for the KC 3300 relay that has two pin 87. You can also make it work with a (more common) standard 5-pin relay that has a pin 87 and pin 87a.

 

Thanks for the diagram, I used that relay shown, I had a few kicking around in my toolbox. The one that came with my wiring kit was different.

All is well and working

Thank you
