I did many a search and learned a lot. Still need more help. 1986 SDL. AC compressor will not come on. All CCU stuff seems to work but I have yet to test the #10 for ground when the AC is on and low pressuse switch is bridged. I'll do that in the morning.

Some questions:

1. What pins on the KLIMA do I jump to turn on the compressor?
2. Is it normal for there to be an empty space in the relay area of the fuse block? It has no plug or anything, just a hole.
3. I have a good used KLIMA relay in the car now but it's from a gasser W126 and I am not sure if it will work with my SDL.
4. Where can I get the specs for all the KLIMA pins so I can see if anything else is bad?

For starters though, I just want to bypass the KLIMA so my AC guy can finish charging the system.

Please help, and thanks in advance.
