Trailer Tow package

[CDomb]

I bought a 2002 explorer with the factory installed tow package. It came with the wires for the brake box. After i had it all set up and attached properly, the brake box doesnt work. Does anyone know if i need fuses or if that is already done? i dont seem to be able to get the answer from anyone and nothing is in the book.
Help!! i need to trailer this weekend. Thanks

I used to have a Blazer in college with the tow package. There were two additional wires (for brake and power) that were just run from the back of the truck to the engine bay. Neither were hooked up to anything (power or the brakes). I wouldn't be surprised if the Expl is the same.
