I think you need a relay that will put the coil across pin 5 and 10.
That way , when the PB is operated it will give the coil ground and complete the circuit [ through the pressure sw and PB unit.]

So, when this happen , the coil will pull in the contacts , which are wired across pin 5 and 7. This will power the clutch.
So, you see that pin 5 is common for both coil B+ and clutch B+.
Whereas , pin 10 is B- for the coil and and 7 is the closing of the relay to feed power from 5 through 7 to clutch.
If you draw this on the schematic , you can see how it works . [ coil across pin 5 and 10, switch across pin 5 and 7]Then you just have to make sure the ice cube inside wireing is applicable to place the coil and contactor pin in the correct places .

Pin 1 is a ground and not needed in this circuit, as you want to catch ground through PB and pressure sw.

UI think there are 2 different type relays , depending on ground switcin g or power switching

Here is an example :

THE COMPRESSOR RELAY CAN BE BYPASSED AS FOLLOWS,USING RELAY # 001 542 02 19 MAKE YOUR OWN JUMPER WIRES. TERMINAL #1 ON KLIMA TO #85 ON ICE CUBE,#10 KLIMA TO #86 ICECUBE ,TERM. #5 KLIMA TO #30 ICECUBE,AND #7 KLIMA TO #87 ICECUBE. CLUTCH WILL ENGAGE AND DISENGAGE AT PUSHBUTTON ASSY'S COMMAND.M.F.
