The previous owner had installed the magnet to the front disc brake. I will see how it was installed.
The speed wire I got with my GasGas Vector screws directly into the brake caliper hole that is provided Yes a plus.
The GG Vector has an external temp sensor for outdoor temp on back of unit.
As for the bike temp I will probably just order one of the options that Trail Tech offers on their website.
As for power I too agree that it is necessary.
Mine is not E-Start so no battery but plan to hook into headlight wiring. My plan is to using ohm meter or test light to find which wire is hot when bike is running.

I will take a photo of my front rotor tonight and reach out to previous owner to see what he did to get the magnet on.
