Whats this then and whats it off..

Too right....

The "this" is the electrical connector to the pressure switch on the power stearing pump.
The "what" is that it provides a signal to the ECU that the pressure is rising in the pump.
The 'why" is the ECU will increase the idle speed to prevent the engine from stalling.

The circuit prevents the engine from stalling when manoeuvring the car at low speed when idling.

Thanks very much for this - I'm about to post a question on power steering, and I'm learning about how it works.
I didn't realize there was a circuit in the system for this - makes sense now when you think about it though!
