The Ender 2 Pro uses a 5 pin JST PH plug. They are standard motors except there is a ground wire they added. This ground wire is on pin #2 of the 5 pin stock plug and is not used when changing it to a 4 pin JST XH. We carry JST XH ends and crimp tools here: JST-XH Type Connector Kit + Crimper Bundle - TH3D Studio LLC
