Air Conditioning Compressor Signal and ELS Circuit Diagram
The picture below provides Air Conditioning Compressor Signal (A/C) and Electrical Load Signal (ELS) Circuit Diagram for particularly Toyota
cars. The A/C signal used to determine when the air conditioning compressor is
loading the engine.

Trying to work out if A/C compressor is dead or wiring harness is dead - or fuse - and how to force a 12V signal to the A/C clutch/drive compressor to get it to start circulating so I can fill up with the R134a refrigerant
