Hi Craig, thanks for the video, @6:50 couldnt you do a continuity test between live wire and ground wire to test the sensor? , also can we always assume that the signal wire will always have either 5v/12v ,eventhough in the schematic diagram it just specifies its a signal wire, but it doesnt say weather it supplies the power or not? (is this what they call pull down circuit? ) also @7:48, when you unplug the pin, wouldnt you get 5v on live and signal only not all the way across.? you will get 0 on ground wire?
