Mine did not have the mine did not have the connector for power or the stepper motors. The power connector is the same - just need to reverse the polarity. For the stepper motors, The xPRO uses 3.81mm pitch connectors and the SLB uses 5.08mm pitch connectors. I ended up ordering a package of 5 sets (1 set is 1 male and one female) from Amazon for $9 (At Amazon).
See my post about my xPRO to SLB journey.
