What is this lever for?

[DogDiesel]

The picture of the vacuum thero switch was not AAZ.

I have the plastic AAZ OEM top neck on my engine now.  It has one connector with mulitiple tiny wires on the drivers side going into the round bulk head connector.  Connected to nothing.

The neck I am talking about is aluminum, from a 1981 1.6N diesel with AC.  My previous engine was an AAZ shortblock with a lot of 1.6 stuff.

I barely dragged out of the best minds on this forum what the lever was for, and the input of how to make it work is my own. 
Honestly, on a Canadian AAZ, I have no clue what made it work.

This weekend, I am installing a new starter.  Mine has a slight drag, and I quit waiting on starters to fail.

I am also putting my Caddy up on jackstands, pulling the rims, cleaning and polishing them and throwing them into another car next week for new tires.  I quit waiting on tire guys to install tires.  Here's my rims, call me when they are mounted & balanced.  Otherwise roll them into a corner and I be by tomorrow.  I am also pulling my speedometer to repair the odometer and tripmeter.  I no longer need to neutralize my engine mounts, as they just went neutral.  Zero vibration, no shudder, perfect shifts.  I will tighten the mounts and smile.

So my Caddy will sit for a week on jackstands.  I guess driving a Mercedes won't kill me.

But I miss driving that lil Caddy...   (did I mention it has a bad case of [damn she] "skoots." )
