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?
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.
