If the connectors on your 2005 Ford F-250 where harness # C56032 plugs into are bad, then you would have to replace that part using either an aftermarket part from an auto parts store or the OEM part from the dealer.

The other option is to hardwire the harness into the wiring on the truck and bypass those connectors. To do that you would need a circuit tester such as # PTW2992 to test the wiring on the vehicle to determine the functions. The 4-Way would then splice in as follows: white wire is the ground, brown is running/taillights, yellow is left turn signal/brake lights, green is right turn signal/brake lights.
