Probably the easiest solution is to hit a junkyard and pick out the best
looking example of that connector that you can find. Then, match up wire
for wire (assuming that the color coding was consistant, of course;).
The absent fourth pin requires ABSOLUTLY NO CHANGE to the existing
wiring. It is simply a deleted +12v power input to the sender that is no
longer used due to a design change in the sensor's internals.
