Trailer Brake Box
The trailer brake box won't work, I tried reconnecting the wires and inspected the wiring harness near the plug at the rear of the truck.
Is there a fuse somewhere that could be blown that kills power to the brake box?

Need a little more info. What kind of box do you have and did you hook it up?
How do you know it's inop?
It should have a fuse on it somewhere.
Do you have a multi-meter?
Check your red wire (should also be the fatest wire) and see if you have 12 volts. Gonna have do some checking here and someone should be able to help.
Also most manufactors have help-tech lines.
Good Luck

Actually all you need is one of those little testers...you know...looks like a plastic screwdrive 'cept it's got a sharp point and a wire with alligater clip on one end and bulb on other. When you clip the clip to a ground, you stick a wire and the bulb lites if it's got juice.....12 volts
