LED Bed light issue

Twilt2019 · January 5, 2020

Hi All,

My 2019 Trail Boss Custom is wired for the LED lights in the bed on each side of the tail gate.

I popped the plastic panels off in preparation for a spray-on bed liner.

And much to my surprise, there are plugs in there for the factory LED's to be installed.

So I bought a couple factory LED's and installed them...but they don't work...?

I would think that they would just be linked to the Cargo Light Switch above the headlight dial, but apparently not.

I've tried with the truck running, and in just accessory mode, with the headlights on and off.

Nothing works....any ideas?

If they didn’t come stock and the wiring harness is there, probably doesn’t have a fuse installed. Check for that and install the proper fuse.

I have not been able to figure this out.

The only fuse I have found on any of the fuse box diagrams is just the one cargo fuse (#34) and naturally, it is in place.

Does this maybe need to be programmed into the ecm in order to function?

I'm rather puzzled. Why would it be wired and then not work?

Can you please elaborate?

My truck was already pre-wired from the factory for the lights. I did not have to run any cables.

That's were the dealership said they plug it in . Other people also have plug there lights in there . It would not hurt to take a look maybe it's not plug in . or check with your dealer.
