Helpful Expert Reply:

Since GM requires that the battery on your Canyon be disconnected for flat towing, you will just need to add the 12V Outlet Kit # RM-9332 to your setup to provide power to your Roadmaster Portable Braking System # RM-9400. This will wire directly to the battery to supply the necessary power for this system, which won't be affected by using the Automatic Battery Disconnect # RM-766 that you also mentioned.

Please also note that you will need the Stop Light Switch Kit # RM-751472 as well to ensure proper operation of the 9700 Braking System on your Canyon.
