Hi Larry -
Klima relay is easy to locate; it's adjacent to the OVP and helpfully has the word 'Klima' stamped on it.
I actually posted the wiring diagram to use a standard 'ice cube' relay to replace the Klima. Let me go see if I can find the thread...
[Sounds of rummaging in closet...]
Here's one which is helpful, but not the one I was thinking of:

OK, here it is:

Note that because your car is a gasser rather than a diesel the wiring of the ice cube relay is slightly different - the PBU sends +12v rather than ground to signal compressor activation. Concept is basically the same, though.
Lack of kickdown shouldn't be much of an issue on your 5-speed car.
Good luck,
