I recommend the Roadmaster Universal Wiring Kit with Smart Diodes for Variable Voltage LED Tail Lights # RO44FR for flat towing your 2021 Ford F-150. These smart diodes are specifically designed to work with the LED tail lights on your F-150. Currently there is not a plug and play version available so the diodes will need to be spliced into the tail light wiring.

Your F-150 does require a Battery Charge Line Kit # RM-156-25 be used when you are flat towing. This will keep the battery from becoming drained while you are towing.

The Roadmaster 7-Wire to 6-Wire Flexo-Coil Kit # RM-146-7 will give you a coiled cable along with a 6-way connector that you can wire both the charge line and lighting. This will clean up your wiring connections into an easy connection.
