So, bought a second hand ebike, but it did not have a downtube battery. No problem, I will slap on an existing DIY battery and just wire it into the Hailong connector. These 5 pin Hailong connectors normally only have Pos & Neg connected but this one has all the pins wired up to the controller.
So I wire up the main positive & Negative, the LCD screen all works, reports speed, but the is no assist from the motor![Stick out tongue :p :p](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Does any know what i need to send to these three pins (Red, Yellow, green)? Found some details which i will detail below.
Google gives me next to nothing back for the controller: LSW943-190f (2018)

Which looks correct, but I'm still not sure were to go from here. Maybe send 5v to the controller on the red "Battery info" pin?
