Its a 88 diagram but it not different from the 85


http://www.911c1.de/porsche/Schaltplaene/plaene1-10_carrera_32.pdf

See ‘blatt 4’ region O21 to P23

Only difference I can see versus my MY85 that on mine the pressure switch isn’t there.

If is is a stock AC system for the 85 there was no pressure switch from the factory. If it has been changed to R-134a the conversion may have included the pressure switch.
