Recently bought the F150 Reverse LED Bars, and when I installed them, they did not work. How disappointing. I checked with my 7 Pin with my continuity tester and found that I am getting absolutely no power back there. I checked the Trailer Relay and Fuse and they were both in working order, and the trailer reverse lamp power fuse and relay in the power distribution box also. I've run out of ideas, so any help would be appreciated!

The power relay and fuse have nothing to do with the turn signals/backup lights/brake lights that you need for the LED bar.
It sounds like you have no ground for the bar or a harness connector has somehow come loose.

Dumb question, but did you have the truck on? There is no power to the 7 pin unless the key is in the on position.

I got one for ya, check the 7 Pin plug behind the Fancy Mounting Plate, I had recently wondered wy my trailer lights were not working and why I had to keep using the Lookout lever on my surge breaks, I crawled under the truck and my Plug was undone behind the 7Pin. I forgot I unplugged it to run my bed light wired, and never put it back. 6 Months ago

what?? for real?
what's the solution?

Feathermerchant

There is a relay to provide power. You can remove it and put in a jumper.
The relay is there so you don't run down your battery.

i just installed the relay from the bag in the glovebox.

relay will let them work though?

Feathermerchant

If it did not before, it should now when the ignition is on.
