KL is the command signal that comes from the pushbutton control that turns the compressor on. That is a GROUND signal!
T is the signal that the engine is overheating, that also is a ground signal form a switch in the waterpump. Ground on T will shut the compressor off.
87 is the power to turn the compressor ON.
87Z is a command signal to the fuel computer to raise the idle.

Additional Notes:
Connecting pin 87z to +12v signal will increase the idle to compensate the AC Compressor.

Thank you mbdoc,
