Not yet used. The guide has a phase connector and a junction box. The instruction video also has a junction box (5). Nothing was included so I had to order elsewhere which cost me another $10. Update: For those of you who need to completely change the direction of rotation of the motor, this is no big deal. From ESC Hall connector: connect and connect blue to yellow and yellow to blue. These are thin 18 gauge wires. Image includedOf motor large core wires yellow to yellow blue to green Latest update: The phase wires were REALLY hot but that was my own fault when connecting the nut and bolt. Make sure you have a very good connection otherwise you have resistance = HEAT. I ended up connecting them with a wire nut which fixed the problem. I was concerned that the phase wires from the motor were much larger, but it turned out to be user error. Motor: I hooked this up to a Monster motoE1000 with a LifeP04 48V 20Ah battery (that thing is absolutely ripping! I'm 6ft 235 and I have a top speed of about 28mph on grass. I'm using it alongside a Juiced Bike with I drove an mph gauge against my son (125 pounds) and we were neck and neck.. bye...enjoy!
