I recommend using the Harness # C55384 which will tee in line of the factory 7-way on your 2024 Ford F-150 Raptor. This will give you a separate 4-way which you can cut off and splice in the wiring from the B&W Custom Headache Rack # BW99FR. Or you could add a 4-Way # HM48192 to the wiring on the headache rack which will allow you to more easily disconnect the wiring in the future. view full answer...
