How To Install A 7 Way And 4-Way Connector To Factory 7-Way On A 1995 Ford F-250 SuperCab

The Hopkins Endurance Multi-Tow 7-, 5- and 4-Way Flat Trailer Connector, part # HM48470, would have to be hardwired to your existing wiring harness. If the 7-way you have on your 1995 Ford F-250 SuperCab is a plug-in connector you will need to sever the wires on the back of the connector. Then, attach each wire from the factory harness to the screw, for that same function, on the back of the Hopkins connector.

If you have a plug on your 1995 Ford F-250 SuperCab wiring harness that matches the plug-in socket on the Hopkins 7- and 4-Pole Trailer Connector Socket w/ Mounting Bracket, part # HM40975, you can use this adapter, but it will only give you a 7-pole and a 4-pole. It does not have a 5-pole connector.

If the plug on your vehicle does not match the socket, then you can use the Pollak 4 Foot Pigtail Wiring Harness for Pollak Replacement 7-Pole RV Socket, part # PK11998. This harness will plug into the back of the Hopkins connector # HM40975, and the pigtail ends will need to be wired to your factory wiring harness. You will need to use a circuit tester like Quickee Tester, part # 3808, and wire by function instead of color. The wire functions by color on the Pollak harness # PK11998, are listed on the product page.

You should be fine when using the 7-way for the camper and the 4-way for the trailer at the same time, unless you have extra lighting or 12 volt appliances in the camper being used when on the road. The extra lighting or appliances would cause too much of a current draw and overload your vehicles wiring harness.

I am including a link to a FAQ page on trailer wiring and a video link to a review on the Pilot adapter.
