There a few dependent devices that are in the circuit...you need the current flow diagrams...
This info is for a '79, but should apply to you.

Well Thanks " JhwShark " to You I made Headway today I decided by Cooling Motor You Must Mean the AC Compressor. ( Not the Cooling Fan in front of the Condenser )
So I Removed My Fan Cooling Relay ( # 9 Socket in this 1980 )
and also the Q Plug at the Bottom of the Wiring Panel
I Jumped the 87 Pin and the 30 Pin of Socket 9 and nothing happened Key on or off
Then Leaving the Jumper I replaced the "Q" Plug and the Condenser Cooling Fan started running . Yea .
Then I Checked the Conductivity From " Q 3 " ( Left side of Q Plug ) to the Cooling Fan Relay and found " Conductivity so I knew I was on the right track THANKS
Then I Checked for Power at Q3 and discovered that with the AC Button Depressed ( engaged ) I had 9 / 10 Volts at Q3 motor off
Motor Running I had about 12.50 Volts
So Now I am on the right track !!!
I wish I knew where I should Look for the Q3 Wire under the Hood Like some wiring Loom or whatever . I Looked all around but see No Loose wires Hanging.
So Unless I go to a Porsche Salvage and see a 80 or 81 Model still Intact I can Look for the wire .
Looks Like However since I am Far up in N Cal I well have to do this as a fix for now .
Run a Wire from the Back Side of Q3 to the Compressor so that when I Press the AC Button the Compressor well Run.
Now I Expect this direct Wiring well mess up all the signals from what you call
the ' dependent devices '

...
I Expect the Cooling Fan in front of the Condenser well not come on until Device
perhaps Temperature controlled tells it to
I have read how some Wire the Cooling Fan to run at any time the AC is on
Perhaps I should do this ? Not sure about that
Any further Suggestions Much Appreciated
By The Way I am familiar with the Electric Panel Board and have worked with it front and Back But never really Dealt with the " Plugs on the bottom before "
Much Regards
