My 2017 F150 extended cab with 8' box has a capped wire harness on the driver side frame rail that terminates next to the spare tire. It has all of the correct wires from the front but the JL3Z-14A412-D connector does not fit the existing connector. Does anyone know if a JL3Z-14A412-C has a different connector configuration that will fit the existing connector? The difference between the connectors that I have are the molded alignment lugs on the connectors don't match.
