My Lentech is wired a differently from most. I've got a single 12V source that goes into the transmission that powers several functions. My TB wire comes out of the transmission and to one side of my button. The other side of the button is taken to ground. When the switch is open (ground path interrupted), the TB is inactive. When the switch is closed (ground path completed), the transbrake is activated, as long as I'm in low gear that is.
