We sure do! To add a 7-Way connector to a 1989 Ford F-150, F-250, F-350 you will need the following parts:

Hopkins Plug-In Simple Vehicle Wiring Harness with 4-Pole Flat Trailer Connector item # HM40125

Universal Installation Kit for Trailer Brake Controller - 7-Way RV and 4-Way Flat - item # ETBC7

I have linked a couple of installation videos below so you can see how to get these parts set up. If you have any additional questions feel free to throw them into the comment box below.

Hey, did the installation videos help you set up the 7-Way connector on your Ford? I'd love to hear how it went, as it could give others confidence when setting up their own connectors.
