There's nothing helpful in the Haynes, it shows the pressure switch, Fuse 19 ac compressor and relay 5 ac compressor and the evap temp sensor( inside car ) all wires go to the engine management ecu .
Maybe contact a professional car ac engineer?

Is that not basically the whole set up for basic aircon
The issue is these things are digital and canbus controlled so you can have the whole wiring diagram but unless you can see what signals are being sent back and forth the wiring diagram maybe of little help anyway, but the OP wanted a diagram and by all accounts it seems Haynes has one
Go to the download section and download and install e learn on your computer. It should have all the wiring diagrams you need plus trouble shooting guides.
