You can add a 7-Way to your 2002 Ford F-250. I have included a link to an FAQ that should help. If there are 2 blue wires, one of them will be for electric brakes, the other has some other function and you will need to test all the wires for function using a circuit tester like # PTW2993 to be sure.

If the truck came with a factory 4-Way trailer connector you can use # 37185 to add a 7-Way.
