Pin assignment in the fuse box

Hello, everybody.

someone knows the pin assignment (schematic) for the fuse box. Specifically, it is slot 11, terminals 87 and 30. I mean, where do I find the other end of the terminals 87 and 30?

Problem:
My 'new' V8 has a manual climate that hasn't worked yet. Now I'm browsing around in the possible mistakes.
First of all, replenish it.
When it still didn't run, I measured the voltage on the climate compressor (magnet coupling), nothing. Checked the fuse box, relay in slot 11 it should be. There wasn't one! That's just what I thought, Relais bought, plugged in, measured, nothing.
This means that the relay attracts as soon as I press the button for the climate, but the load circuit (clamps 87 and 30) does not have any voltage.
All fuses are i.o.

Thank you and greeting
Jörg
