So I got a used emove scooter that had the ignition bypassed because there was no key (police auction $60). When I first got home I would be able to ride it about one block on a full charge and it would just lose all power. So I decided to take on the daunting task of building the whole thing I've already built the battery which is a 14x6 setup and now I have the sine wave controller that has basically matching ends for the hall wires, the motor phase wires, the power, and that's where I have to stop because I don't know how to connect the other wires on that controller to the scooter because they don't match anything I got six pins and four pins and two pins... I just need someone's help please thank you in advance! PS I no longer have the print circuit board that came with the scooter which probably is a big deal but that's the way things are, do I need to replace that or can I work around it? I've wired up scooters in the past that were nowhere near this complicated so that's why I'm reaching out
 
Maybe post a picture of the new controller. It should have come with some kind of wiring diagram.
The original display and throttle will most likely NOT work with your new controller, so you will probably need a new throttle at least.
 
Yep I bought a simple 3 wire throttle in case it's going to be necessary. The controller is actually from varo motors, and is supposed to be for this scooter, but a different version than stock one. My confusion is mostly centered around the wire colors and quantity not matching up

It’ll take a lot more words to describe the amount of info that one picture can provide.
Did you get the controller to turn on? That’s probably necessary to trouble shoot the rest. Usually if you can turn on the controller, then the throttle, battery, and motor is all you need to get the motor to spin, although I would get the controller to turn on before connecting the throttle to test the throttle pinouts for the 5v supply.
