The LH2.4.4 ECU is digital based not analog. Its either ON or OFF. Its either Ubatt or Ulow.

Regarding pins 14 and 15 you should refer to latter wiring diagrams such as for 1994. In that diagram there are arrows which either go in or go out of the ECU. Pins 14 and 15 are labelled with "arrow in" which means the ECU only receives voltage input from compressor (pin14) and AC module (pin15). No voltage input means OFF. Since you don't have any resistors in the ECU for AC that leaves it out for causing idle increase.
