According to my research you'll have a factory connector on your 2021 Land Rover Defender but there aren't any custom wiring adapters to fit exactly with it so to install the Prodigy P3 # 90195 controller you'll need to test the pins on your factory connector and then splice the Prodigy pigtail wiring to the following functions on your vehicle:
Blue - 7-Way Output to Trailer
Black - 12V Power
White - Ground
Red - COLD Side of Stop Light Switch (only gets hot when brake pedal is pressed)
If you don't already have the P3 and you're looking for a simple installation that doesn't have you splicing wires on your vehicle I recommend checking out the Curt Echo In-Line Wireless Brake Controller # C79DR instead. This tees in behind the 7-Way at the back of your vehicle and the module installs under your vehicle. You'll then use the app on your phone to monitor and adjust the trailer brake settings.
I've attached a review video of the Echo In-Line for you to check out!
