ok,tough to explain right. In order from your gauge to the water, it goes wire, sending unit, adapter, then water. The sending unit itself has to be grounded. Where the wire comes in the top, that part puts out the signal. If you want to test this theory, turn on your car and let it warm up, then take a piece of wire and run it from the neg on your batt to the side (where the hex is for the wrench to grab) and watch the gauge work. Mine started off kinda working but was inconsistent. As it turns out, the sender was grounding thru the water to the head. weird. hope this helps.
