What a great question Howard. You should direct that request to Curt, Blue Ox, or Demco though. We don't make the wiring harnesses like the Curt item # C75WR you purchased, which does not have diodes in it. No one makes a plug and play for a 6-Way flat towing connection.
The diodes included in the Roadmaster Smart Diode Kit for Variable Voltage LED Tail Lights item # RM38FR, or item # RM-152-1676-7 if you don't have LED lights, are installed to prevent feedback between a RV's electrical system and your F-150. Without the diodes, your RV's turn and brake signal could cause your F-150's lights to flash the wrong lights or short circuit your entire electrical system.
Do you already have a supplemental braking system for flat towing your 2024 F-150?
