[urq] WX Engine Oil Pressure Switches

[Buchholz, Steven]

... is your car ... namely the engine ... stock?  What you are
describing is the set up for the cars with the "dynamic" oil pressure
sensing system ... an MC engine would have this, but I was not aware of
it being installed on a WX.  

The dynamic system uses the standard 0.3 bar switch to directly light
the warning light on the dash.  The 1.8 bar switch goes to a module
which also receives info on engine RPM ... if the engine speed is above
a certain value (2500 RPM?) and the 1.8 bar switch is not activated the
module lights the warning lamp ... 

It sounds like your car is wired the way it should be for a WX.
