Hey guys need a little help. I've got a 2014 sierra crew cab. My issue is that every time I plug it in to the truck the trailer brakes lock up. Everything else works but the brakes. My friend just unhooked it from his suburban with no issue and I got it home with my friends 2010 silverado. I checked the controller the wiring and everything looks good. I've plugged it in and pulled the trailer fuse and it still locks, disconnect the controller and it still locks up. I figured I'd ask for help before I send it to the dealership for them to look. Thanks in advance.
