The Hall Effect sensor wiring?

[LaughingJack]

I've spent a little over two hours searching the forums now and have had little luck. Although I've gained some new valuable information I still have a pitfall in my knowledge. I've reviewed all the threads I've found and searched the official schematic for the sensor and I am still a little confused . I was wondering if someone could post a simple diagram of the wiring (because i can't find where the four prong connector goes.) or if they could give a simple "verbal" walk through in it's connection. Is my problem with the external connection of pins 3 & 4, or am i just missing something obvious. Anyway any help is appreciated and thanks in advance.
