Help.... today i was coming out of work and noticed something hanging under my car (82 Z). It is a connector square in shape with for round pins... does anyone know what this is for and if so where does it go. Thanks in advance for any help.

 

If it is hanging from the drivers side it may be the connector for the knock sensor which I believe is on the down on the side of the block on the drivers side. (I THINK??????)

 

Sounds like the TCC switch plug. It goes into the bottom part of your tranny.
