I have a blue and red wire hanging under my bike next to the stand.
Am I right in thinking it's for the oil pressue sensor? 
If so, does it just connect under the screw in the sensor.
If not, where do I put it?
TIA

Yes, the color matches the Oil Sensor switch wire color code...........and yes, normally i'ts got a felmale plug to go into the sensor, and that's it.     The ground is the sensor body and the engine.    It should work if the sensor is OK

The connection I can see isn't a plug. I don't know the correct name for it, buts a circular connector with a bit cut out, not dissimilar to a circlip shape. 
it's obviously been clipped onto or around something at some point, I judt dont know what.

Yes, the blue/red is the oil pressure sender wire and it should go under the screw on the sending unit.

Here is a color wiring diagram.  www.kzrider.com/filebase?task=download.send&id=281&catid=62&m=0

here is the factory service manual, though the wiring diagrams are sadly black and white.  www.kzrider.com/modules/ServiceManuals/Kz400500550_79to83.pdf
