I am not too sure as I never have a need to jump any SDL compressor. Ignore the rpm sensor wiring at the back of the compressor. Whatever left is the coil wiring for the clutch. It may be chassis ground plus 1 terminal. First measure the harnesss to see whether you have 12V with one of the pin to chassis when you jumped terminal 5-7 at the Kilma. If you do then the compressor is bad. If you don't then the problem is upstream. You can put 12v to the compressor terminal and you should hear a click. Be careful if you have the engine running. Good luck.
