LT10s and dash-unit with OIL_P function

I have a problem with the dash unit and the oil pressure display "OIL_P".
When the blue/red wire goes to +12V nothing change on the dash display.
Whatís wrong here?

What is the different between the OIL_P and the "two-step" functions?
Both of these works with the blue/red wire. Isnít it?

And btw. which function does the white/orange wire have?

... bring it up again. Does nobody have an idea?

Here a clipping from the "MicroTech Advanced Tuning Manual". :
... If an error is detected by the Dash, the high intensity master warning light (left hand amber lamp) will switch on and a warning message will appear in place of the water temp / boost display on the MAIN screen or in place of the injector open time on the Dash screens.
The error codes are: Water_T, Air_T, Battery, Boost and Oil_P (requires the fitting of a standard oil pressure switch to the Blue/Red AUX Input wire of the MT ECU. Refer to the wiring diagram supplied with your MT series computer). ...

It doesn't matter is the blue/red switch to GND or to +12V, like the diagram shows.
No reaction on the Dash screen.

Can anybody help me please?

Sorry - for bringing back, but is there anybody who knows something about:

1.) How does the OIL_P at the "dash-unit" workes? At the "Advanced Tuning Manual" is talking about the blue/red wire.
2.) Which function does the white/orange wire have?

thanks guys
