No power to brake controller

[MR12008]

I have a 2001 f250 superduty with 7.3 diesel. I'm trying to wire a trailer brake controller. I have power from the brake but none from the battery. I just bought the relays that go under the hood what else could i be missing maybe a fuse or something?

yes it could be a burned out/missing fuse. check your owners manual for the fuse diagram.

I think there is a 30 amp maxi fuse under the hood.
