2021 JT 3.6 Fuses - Diagram, Location, Description, Count & Spares

Brake light fuse help needed.

I need to install a “Brake-lite Relay Kit” on my ‘24 Gladiator Mohave for dingy towing the Gladiator behind our motorhome. The first step in the installation directions, annotated with cautions and warnings, is to remove the brake light fuse. I don’t see the brake light fuse listed under the fuse panel cover, nor on the diagram above. Does anyone know where this fuse is located?

The BCM controls the brake light signals. There is four fuses (F20, F26, F28 & F29). F26 and F29 are label for exterior lights but I would pull all four to be sure.

Hoping somome here can help. I have a 2021 Gladiator Rubicon and our 12v outlet in the truck bed doesn’t work. I replaced the fuse for the cigarette lighter hoping that would fix it because the one inside didn’t work either. Now the one on the front panel works but the truck bed is still not working. I matched all of my 20a to your diagram and it matches exactly but none are labeled anything that would make
me think it’s for the 12v outside. Thanks in advance.

There is no factory installed 12V DC outlet in the bed, just a 115 AC inverter outlet. If you bought one with a 12V DC outlet in the bed, then someone added that after the fact and would be anyone's guess how that is wired up.

Attached is the wiring diagram for the 115 Outlet if that is what you actually have.

Looking for the center brake light. It's not working, but every other light works.

I see F20, F26, F28, and F29 are related to exterior lights. Can anyone narrow it down for me?

Of course, it could be something else. Maybe the light itself failed?

Those are all 30A and 40A fuses. Any one of them blown, and you are going to have more than the CHMSL light out.

Better off pulling the inside tailgate access cover off and taking the connector to the CHMSL off and measuring for voltage with the brake applied. Very high probability it is going to be the light assembly.

That´s a great idea! Thank you!

I agree...I´ve been doing a lot of searching and there are a ton of these failing. I found one on Amaon for about $77 after tax.
