ElectroCraft made many motors for OEM's so yours may be a custom version, The 660-07 is a 60v 4600rpm cont torque 122 0z-in dc motor, yours may have a tach which is not generally used now, I would guess that the red/blk are the motor pair and the blue/white are the tach.
If the blue white pair come off the rear of the motor this points to the tach position.

You can confirm the voltage rating by rotating the motor a known rpm by external means and measure the voltage and extrapolate it for 4600rpm.
Or apply a certain known voltage and record the rpm.
