ready brake indicator light - where to tap into

This indicator light illuminates when the toad brakes are applied to let the MH driver know 2 things: the toad's braking system is working and the toad brakes are not sticking on. The 2 wires need to be spliced into the toad's brake light circuit. Because of so many wires on my toad's brake switch located on the brake pedal, I ran a wire to the back of my toad and and connected to the wire that operates the toad brakes. The other wire I connected to a ground.
