Hi chaps I purchased a cheap controller off amazon. Unfortunately the seller has not replied when asking for a manual, I'm assuming there's some kind of key switch connector as it won't work on my bike, any ideas?20240530_174149.jpg

Fwiw my approach would be a google image search for the brand of controller and the keyword "pinout"

Below the battery phase and motor sensor wires separated to the top of the image, you have the plug with the blue/white wires coming out into a seperate plug, this i suspect is the key switch, the throttle i suspect within the remaining wires in the bigger plug

Further guesses the black/grey red/grey could be lights front/rear forming a + to- circuit?
And now looking at how the 1 3pin plug fed by red/black wires feeds into the plug above it in the image i now suspect that as the switch? - yeah google image search ... keyword 'pinout'

What is the make and model of the controller?

That wiring diagram bears absolutely no resemblance to the wiring on your controller.

I'm going to guess that it's a controller for a specific application, like a scooter that has lights, instrument display and remote fob type ignition.

Black and white are for brake cut-offs, the motor phase and hall wires are obvious. The throttle is on the multipin connector, but which wires is anybody's guess. You neet a meter to determine which wires are 5v and which ones are battery voltage. The rest is optional except that there will be a couple of wires that need to be joined for the ignition. The other connector with two red wires looks like it's for a switch that either switches the throttle off or the battery power off depending on its voltage. The only way to be sure about the ignition wire is to open the controller and see which wire is soldered near the big resistor.
