Looking for ground point Z6/16 for AC sensors

[744Brillantsilber]

I have a question for those who parted out a W124 or had the interior appart:
Where is the ground point Z6/16 located?

It is the ground for the following temperature sensors:
Heat exchanger temp
Interior temp
Exterior temp
Condenser temp
Coolant temp for ac

To be precise Z6/16 is a connector sleeve somewhere in the harness, not a ground point.

Hello Paul,
thanks a lot!
My bad, English is not my native language. You are right, I am looking for the place where the connector sleeve is located in the car.
Ground comes from the righthand wiring Pin 12 and goes through the control unit to Z6/16
