You have no pin 4, so all you need to connect is Pin 12, that's the only sense lead.
Here's the relevant diagram. After this, I start charging for engineering:

The heater core and receiver dryer was leaking so I dove in and decided to fix up the old girl ALL the way.
Replaced:
Heater core and Evaporator.
All vacuum elements ( except for the defrost one - out of stock worldwide- and still works )
Feedback potentiometer
New style switching valve.
Pushbuttons
Klima relay
Receiver dryer with both switches.
To the best of my ability I did all the tests to this system by the Tempmatic book.
Tried second pushbuttons and klima relay.
Grounding one wire of the low pressure switch does kick on the A/C compressor. Same with jumping pins 5 & 7.
