Hard Wiring a 1999 Ford F-350 to Have a 6-Way and a 7-Way Trailer Connector

Question:

I have a 1999 ford F-350. I have the old 6 way round plug, I would like to install the newer 7 way blade as well. Do you have a T that would plug into the wiring harness so I can have both on my pickup without having to buy an adapter to fit in one plug or the other, I have purchased several of these plug to plug adaptors and lose or someone borrows them for long term, so I want to have both wired and ready to go.

If you want to retain the 6-Way connector at the rear of your vehicle and install a 7-Way connector also, then I would use the Adapter 4 Pole to 7 Pole Vehicle End Trailer Connector, item # 30717, and cut the 4-Way connector off of the adapter. I would then splice the wiring for the 7-way connector into the correct circuits in the 6-Way connector, using a circuit tester, item # PTW2993, if you need one, to verify the correct circuits. You can then splice the remaining circuit on the 7-Way connector to the circuit needed on the vehicle. You can use the Mounting Bracket for 7-Pole, RV-Style Trailer Connector - Vehicle End, item # PK12711U, to attach the 7-Way connector at the rear of your vehicle.
