With the [schematics] and [SJM page] (see the 0.2 + 0.2 Ohm resistor pack at 85% of the page, mounted under the main radiator on the main console) it is possible to identify/verify the relays that switch on the radiator cooling fan in different power-stage (3 stage system: 0.4, 0.2 or 0 Ohm series resistor).


A/C Control

We have a universal pressure-switch in the high-pressure tube (after compressor), with 2 blue, and 2 black-green wires:

NOTE: now, after they filled the system with R134A gas (with engine off),

Clutch control

AC main 30A relay

  • Optionally it can also switch on a small "raise-idle" solenoid (normally not needed when there is an IAC valve)

Radiator fan (on low-power) relay, or a 2nd circuit of the above relay

Fan stage2 relay. DONE, reused factory relay
