I will check again after work, I did not want to force the connector yesterday.
The scanner looked to have a keystone shaped plug, ( wider on top, sides slanted in ). The plug under the steering wheel seemed to have oval ends/sides. But my eyes are not getting any better, and so on etc.

Thanks I will check this out again, I will feel like a dunce it this is it...
