Missouri | I am not certain of the pinout, but I will tell you what I think it is.
Pin A 12 volts positive
Pin B signal
Pin C 12 volts ground
The new style sensor is a powered sensor. It must have power and ground in order to work. If you're not gettting it to light up, I would check for a ground on a pin.
You have two switches, and they are teed together. If one of them is shorted, and sending signal all the time, you will need to disconnect them one at a time to figure out which one it is. | |
