Question:

All my other lights work but I have no trailer brakes. Which relay controls the trailer brakes in my 2014 ram 2500 6.7 cummins?

I took a look at the online version of your 2014 Ram 2500 owner's manual. It looks like there should be a 30 amp pink fuse located in the F11 position inside the power distribution box (under the hood). This particular fuse is for the integrated trailer brake module on the truck. Make sure this fuse is present and in good condition.

If the fuse is good or replacing it doesn't resolve the issue, please let me know and we can continue to troubleshoot.

I have the same problem and that 30 amp fuse is not blown! Have you ever come across any other problems? I have checked it with one of those plugs with the Leds and the brakes don’t work and it doesn’t appear to have a trailer connected to it on the dash

For your trailer wiring to work, some "smart" vehicles require seeing the trailer connection. That trailer connection on the dash is often connected to seeing a power draw at the trailer brake output. It is a slight draw that even connecting a non LED circuit tester like # 40376 will cause enough draw to sense. LED testers simply don't pull enough power for that connection to be seen. This will help you check that 5 o'clock pin (brake controller output) in your 7 way to determine if there is an issue on the truck side or if the issue is on the trailer side. Note that even corrosion in the trailer connectors can cause an issue with that function and a little sand paper can solve it. If it is on the trailer side, you will want to check all your wiring for any missing insulation or corrosion. You will also want to check each ground wire to make sure it has a metal to metal connection free of corrosion or debris.
