If you're clocks are mechanical you can't use a transducer to get a reading from the gearbox

theyre electric clocks pal. ive got wires coming from the transducer now but i dont know which is live/earth or signal on it? plus i dont know where the signal wire goes to behind the clocks. say youre looking on top of the transducer from the front of the car, is it live earth signal on the pins from left to right?
