My truck came with the tow package, so the factory harness under the dash for the brake controller is fed by a 30 amp maxi fuse so it's good to go. It would be nice if they made a drop in blade type circuit breaker for maxis. Do those exist? I'd rather have a resetting CB than a maxi on the trailer brakes.Electric brakes are not low amp power though. Reccommended to use a 30A CB for supply to the controller, and, 10 gauge wire. To the controller and from the controller to the connector, and on back to the brakes themselves.
