Hey Lost_To_A_K-Car, I sent the full diagram in big size to you. Let me know what you think.

Remember, the image was taken from the ALLDATA website, but is the same as in the manual.

Where, physically, is the "ambient switch" noted on the diagram?

It's a small sensor installed at the air inlet, below the front bumper. It's function is to measure ambient temperature so that, below a certain degree, it turns off the idle control.

This is because at low outside temperatures the refrigerant is more fluid, so the compressor needs less effort to work it, no need to accelerate the engine. That's what the manual explains.
