I am wiring my brake light system. I purchased a power booster from Summit it has this one wire terminal coming from it, not sure what it is. I bought a brake light switch from O'Reilly's part#2-8605. It is a two terminal brake light switch, the switch is closed (on) when it is not depressed and open (off) when depressed. I'm thinking i need the opposite; is my thinking correct, do i need a different type of switch if so what type?
