Help wiring Yuan Lang 48v controller

Hello! I have tried contacting Juan Lang for a Yu Xin 3 wheel trike with 3 speed 48v brushless motor to get a diagram of what colors are supposed to connect to what but have not had any luck. Does anybody have access to tell me what these color wires are for? There is throttle, reverse, lights, horn, 3 speed, ignition then obviously the brushless controller. I’m finding that mine does not match colors of any other controller so I find online

I can usually tell just by looking at a controller, sometimes with a Voltmeter or opening them to read the letters off the PCB.

If you could post a pic that'd be great too.
