Light Bar

So I've trimmed the bumper of my 2007 Jimny and so my spotlights are gone. I was thinking of somehow connecting the wire that clips off from the passenger side spotlight and using that to connect to a light bar, this way I will be able to use the same switch in the cabin. Does anybody know how I would go about doing this and what light bar would be suitable?

Hi Colin, I would think it would prudent to use the original foglight feed to run a relay to a new fused supply from the battery, to the lightbar..

I dont know much about electronics so I haven't really looked into it that much. What is the normal way of installing a light bar?

Here ya go Colin

How to wire a Relay and Why You should use them

Simply connect the 2 wires from the spotlight to the 2 wires on the light bar. You will need to cut off the old connector and crimp on some new connectors. Insulated spade or bullet connectors are the simplest choice. Make sure the wires that powered the other spot light are tucked away safely and insulated to prevent corrosion. The original fog lights are halogen, which draw a lot more power than LED, so the supply is more than adequate for a light bar, and the supply is already fused for safety. No need to add a relay!

I have removed the entire lower bumper and am only left with the wire that feeds to the passenger side spotlight, the one that separates off from the other main headlight wiring harness. Is this the wire that I connect to the light bar wiring?

Yes, that's the one.

This is true and probably ok for the light bar you have. But lots of LEDs together can easily draw more current, so in simple terms make sure your light bar watts is no higher than your original light watts. I believe the original fog halogen lights are 55w each, so you should be good to directly fit a LED bar upto 110w (Normally they are less than the max stated).
Just saying as my LED bar is 180w and definitely needs a relay!

The fog light supply is 15 amps so suitable for up to 180w.

Yes its good for 180 - 212 watts depending upon battery voltage, but its bad practice to run the circuit protection at 100% loading. Typically you run at 75% of max rating to avoid nuisance blowing or stress on the fuse.

So would I be able to run from the original spots feed meaning the factory switch in the cabin will switch the light bar on and off? And whats the difference between adding a relay vs a fuse?
