preasure regulator control
 

Does annyone know where the preasure regulator control module and solenoid valve are lokated.
And do all S12's have this?

I really need to find this module cause i have to check the whole wiring loom.

My car wil only run on false values by cheating the water temp sensor by connecting the ignition signal thru a resistor between the loom and the water temp sensor.

I've been checking all the wiring shemes and it says the ignition signal and al those sensors are connected thru the pressure regulator control module and solenoid.

I just cant find it.
Is it possible my 84 LHD model doesnt have one?

I'm really stuck here.
