Where Are Trailer Light Fuses Located At on 2021 Ram 2500


Wondering what fuse I should check if my trailer brake/turn signal lights on the drivers side of my 2021 Ram 2500 are now working. It’s not the trailer because it’s happening on more than one of my trailers.


Expert Reply:

The trailer fuse locations for a 2021 Ram 2500 can be found either in your owner's manual or on the underside of the fuse box lid. I have attached them for you below as well.

F28 20 Amp Blue – Trailer Tow Backup Lights
F29 20 Amp Blue – Trailer Tow Parking Lights
F30 30 Amp Pink – Trailer Tow Receptacle / Trailer Tow (Separate E-Brake) /Trailer Tow
F38 30 Amp Pink – Integrated Trailer Brake Module
F53 20 Amp Yellow Trailer Tow – Left Turn/Stop Lights
F81 20 Amp Yellow Trailer Tow Right Turn / Stop Lights

The only replacement parts we offer for the trailer wiring is the connector, 7- and 4-Pole Trailer Connector Socket part # HM40975.
