I took a look at the online version of the owner's manual for your 2011 Ram 2500 and found a couple of fuses you will want to check inside the power module located in the engine compartment. There should be a 40 amp green fuse located in the J01 position and a 20 amp blue fuse in the J14 position. Both of these fuses are related to trailer lights so you will want to check to make sure they are present and in good condition.

If the fuses are good and you are having issues with the trailer running lights, please let me know and we can continue to troubleshoot other possible causes.

Chris R. Thank you so very much! I also have a 2011 Ram 2500. I rented a U-Haul trailer tonight and once it got dark noticed that the running lights were not working. I found your message as well as the burned-out 20 amp J14 fuse within a few minutes. I swapped out a 20 amp fuse from a circuit that I wouldn’t need tonight and I’m on my way again. Thanks again – you’re a lifesaver!

This information was 100% spot on to solve my issue of not getting 12v at the 7 pin connector on my 2012 Ram 2500. The 40a fuse at J1 was blown due to the body shop f***ing up my trailer wiring harness when they replaced the driver's side bed side. Thanks!!!
