I have a 2025 Ram 1500 Bighorn, and put on an aftermarket trailer brake controller, but couldn't find a harness that would plug and play, so I cut the end and connected it to the truck's plug. Unfortunately, I messed up and plugged the white ground wire into the main power wire for the controller, I think blowing a fuse. I cant find out which fuse controls that power wire. I have checked all the fuses that these posts recommend and cant find a bad fuse. None of the diagrams I have found online look like the fuse block under the dash, and havent been able to find a bad fuse in it. Any thoughts?
