Light Bar Help

Just picked up my 2017 a month or so ago. Has an aftermarket bumper with a 30” Baja Design light bar… it decided to stop working today and i have no idea where to start to see why, this is all new too me so any help is greatly appreciated?

could it be a fuse? Where are these usually wired to?

 

It was all done when I bought it so im not sure what exactly the last owner did, i have to wait till tomorrow for daylight to see more.. butnill look for that!

 

Check the fuse, ground, relay and switch in that order and then verify there's no chaffed corroded or broken wires or connections before replacing what's not working assuming it isn't the wires or connections themselves.

Where they get wired is a total dice roll if you didn't do it yourself, jus find the pigtail from the light bar and follow it back to where it is connected as part of your chaffed/shorted wire check.
