Question:
When flat towing the Canyon, the vehicle battery must be disconnected by removing the negative post clamp. Is there a different wiring diagram for the Brake Buddy to accommodate the vehicle battery disconnect or should the Brake Buddy still function as designed if I follow the standard wiring diagram as provided in the installation manual?

You will want to follow the same wiring instructions. The Brake Buddy Select 3 Portable Supplemental Braking System item # HM39524 includes a wiring kit that wires directly to your battery. This portable braking system is designed for flat towed vehicles like your 2022 Canyon that require you to disconnect the battery which kills your 12v plug.
This wiring kit will also prevent your battery from dying while towing. Some of the accessory functions on your Canyon will still work and draw power even when your battery is disconnected.
I have linked an installation video below that will specifically show you how the included wiring kit installs.
I have listed some other parts you will need to flat tow your Canyon below. Please feel free to email me directly if you have anymore questions.
Roadmaster Direct-Connect Base Plate Kit item # RM37VR
Roadmaster Nighthawk All Terrain, Non-Binding Tow Bar item # RM-676 (Safety Cables Included)
Roadmaster Universal Hy-Power Diode Wiring Kit item # RM-154
Roadmaster Automatic Battery Disconnect item # RM-766. I highly recommend this kit because it allows you to disconnect your battery with a flip of a switch instead of having to manually disconnect your battery every time. If your Canyon comes with 2 batteries this system does not work.
I linked an installation video specifically for the disconnect kit below. It was put in a 2021 Canyon but the steps will be the same.
