Hey Matt.
The Roadmaster Universal Hy-Power Diode Wiring Kit # RM-152 would work for your 2023 Ford Bronco unless you have variable voltage tail lights. Variable voltage tail lights use the same wire for the brake signal and running lights instead of the standard turn/brake wire setup. To determine if you have variable voltage tail lights you'll need to pull the tail light out to get to the wiring and test wires with a probe tester # PTW2993 in order to see if the same wire powers both the running lights and brakes.
If you do have variable voltage LED tail lights then you'll need the Roadmaster # RO44FR for LED's or part # RO94FR for incandescent bulbs.
