I am having one heck of a time. I just put new lights on the back of my truck and was a little reckless when doing so. I shorted the wires at one point not realizing that the brake lights were on due to low air, now everything is hooked up properly and all my lights function like they should except for my brake lights. I have beaten my head against a wall looking for a diagram / schematic so I can figure out the proper fuses/breakers. I'm wondering if there is a inline fuse or fusible link on this? As far as I can tell I have all breakers installed on my fuse box inside the cab. I have no brake lights on the chassis or on the body. Any help would be greatly appreciated.

Any clue in hell where I can find my expansion valve on a 2017 Granite dump truck GU713?
