Thanks MC. the connector has two options on the press plate (no idea if that what it called but it the plate that pushes the wire in to the v on the pin) one is complete so looks like the wires have to come out the ends and the other has a slot down the middle which seems the best option for the cables but not sure how best to crimp it.

The motor and drive is for a very small lathe spindle (emco unimat pc) so vibration and movement will be minimal.
