Question:

Hello, Could you please tell me where to attach the red wire on a brake controller in this vehicle. The wires that feed the brake switch are extremely small. Thanks

For your application I actually recommend using the Roadmaster Universal Stop Light Switch Kit # RM-751000 to send a brake signal to the brake controller. I looked up the online version of the owner's manual for your 2022 Toyota Highlander but it didn't indicate what color you'll connect that red wire to. This universal kit basically creates that signal for you so you don't have to tap into your OEM wiring.
