Ah ha, I found the connector. I never would have thought to look over there considering the length from sensor wire end to wire harness connector is about 2 too short, and thats stretched in a way Porsche never would have designed.
This 2.0L motor replaced the 1.7L carbed motor that the PO had in this 73, so my guess is the harness wire on the donor car was longer than the wire on this 73.
In any case, I got my question answer. Thanks guys!

P.S. I'm surprised I couldn't find this in the Haynes manual? Oh well.
