I added a couple pictures of how I mounted the switch, the wiring is is so easy that I didnt take a pic of it, I simply tapped into the wire that goes to the brake light wire on the master cylinder, connected it to one lug on the switch, the other lug connects to a ground and that's it. I bought the switch at NAPA a year ago for another project so I dont have the model number anymore, it is a brake light switch that is normally open, meaning when the button is pushed the circuit opens and when its released it closes the circuit activating the light. Its opposite how a regular switch works.
