Question:

Do you have the same harness with the factory 7 way AND 4 way? my 1999 f250 has the grey square plug and the 7way/4way but the wires are all messed up from the previous owner and I can only find the 7way with 4way for the round type plug not the square like part 118243. Thanks,

In order to receive a wiring harness for your 1999 Ford F-250 that plugs into the square tow package wiring port and provides you with both 4 and 7-way trailer connectors you are going to want to purchase the Ford Replacement OEM Tow Package Wiring Harness part # 118243 and then swap out the included trailer connector for the Hopkins Endurance Multi-Tow 7-Way RV and 4-Way Flat Trailer Connector part # HM40950.

Unfortunately, we do not offer a wiring harness for your 1999 Ford F-250 that plugs into the square tow package wiring port and provides you with both 4 and 7-way trailer connectors so the above will be the only option we have for you.

On part #118243 do you offer just the harness by it's self. That is all I need.

Unfortunately just the harness by itself isn't available as a separate part. You'll need to go with the whole kit that includes the 7-Way connector and fuses.
