Hello All,
I have searched the forums and the interwebs for some help on this specific sensor but cannot seem to find anything that shows what I need so I am turning to the enthusiasts for assistance. I have a dual temperature switch part number 13621703993 and I need to know what each of the four pins are for. This one has 4 pins all labeled 1 though 4, so I know I have ground, power, signal 1 and signal 2 but I have no idea which is what. Can anyone help me with this? I do appreciate any assistance you can offer!
