Standard 7-pin connector shows pin 2 (usually blue) as the brake power wire. If you have power there when the controller manual handle is moved, then you likely have a wiring problem in the FW. First place to check is good ground wire. Second, make sure the wires in the plug are good. If you can jack each wheel, you can see if you have =any= braking at all. If you have no power at the truck, then check fuses, then start checking truck wiring. If you have another truck available, plug in to that and see if you have brakes. That can narrow it down to your truck, too. Any thing else, and you're having to chase wires on your FW.
