Right so I took the motor apart and it is simple, motor ground and 3 switched grounds for the park, intermittent and hi/low.
2 lives go to the motor pins via resisted brushes. X2 so intermittent /park then low then high. 1x ground brush.
They connect through the track and to the brushes.
Something like that anyway.
2 pins were worn so I've cleaned them up and sanded them smooth and bent the arms a little. Left my meter at the van but I'll do some tests because I now know what pin is what.

The 3 pins I might need to double check the numbers lol possibly lost in testing but they're all ground anyway.
