Compressor Magnetic Clutch Circuit

The air conditioning control assembly outputs the magnetic clutch ON signal from terminal ACT to the ECM.
When the ECM & TCM receives this signal, it sends a signal from terminal ACT and switches the A/C magnetic clutch relay on, thus turning on the A/C magnetic clutch.
