The new motors are 4-wire 1.8 degree (I think they are bipolar parallel type but am not sure about the proper description) and they come with a plug that does not suit the EQ6 control board and will require either a new plug or some form of adapter. But either way, I'm wondering if anyone knows which are the A, A+, B and B+ wires on the standard EQ6 motors so I can match them up with the new motors. (The product description does not use the + symbol but instead has a line above the letter - like a minus sign on top of the A or B).

It is easy, if you have the multimeter:
A-B must have some resistance (100 ~ 200ohm or so), C-D should be the same.
Between A-C and B-D there should be open circuit.
You should use the motor which works in both places as a reference.
If you swap A and B, or C and D, the only consequence will be the reverse rotation of the motor.
