Just considering/researching whether a CAN emulator/extender might be of use here, if the AC switch is my biggest stumbling block. Something like a CANNY 5.2 or a CANNY 7. The 5.2 might even come in handy if in the future I was considering something like replacing the factory
ECU with a Haltech if, perchance, I get as far as adding a Turbo later on, and needed something to simulate CAN messages....
