Andy - sorry for giving you the wrong steer! It sounds like you do have a motor with sensors, as Nick correctly inferred at the top of the thread.
It was late at night right before I went on holiday when I saw your post so I didn't have time to look into it properly - and was consequently talking nonsense!
So you, and any others who get one, can recognise it, this is what a sensorless eCrazyman controller, suitable for a Tongxin, should look like.
The sets of wires are (from the left)
Throttle
Pedelec sensor
Brake cut-outs
Battery
Motor wires
Hope this helps, as and when you get your controller.
