			=== Controller ===
			An Arduino MEGA-based controller has been developed by DIYEC user ''Classic Style''. Details here: https://www.diyelectriccar.com/threads/tesla-a-c-compressor-questions.189978/post-1067794

			=== Integration with aftermarket HVAC ===
			It has been pointed out that a typical HVAC trinary switch will provide a 12V signal to enable (might be typical on ICE compressors), however, in this case the Denso ES34C is looking for a GND signal to enable (pin 2 - ON/OFF). As per: https://www.diyelectriccar.com/threads/tesla-a-c-compressor-questions.189978/post-1075637, DIYEC users ''jsimonkeller'' and ''DANTM'' managed this simply by using a typical automotive relay to invert the signal and switch GND instead of 12V.
