Hi everyone,

I need your help and opinions about a subject. I have an old ebike with a 24v motor. I wanted to replace its controller and ordered a new one. Today, I received the new controller, but the wires of the new controller look different from the wires of the old one. I could find and connect; phase line wires (green, yellow and blue wires), hall sensor (the socket with 5 wires), power wires (black and blue wires, and throttle wires (black, red and white wires) but I couldn't pair some other wires.

I took the pictures of the wires which I couldn't pair.



- In this photo, there are 4 sockets; the one with black-red-white comes from the throttle and I found that socket on the controller. - The one with green and yellow wires comes from the button on the throttle, but I couldn't find where it goes.
- The one with blue and red wires goes somewhere from the down tube. I don't know where it goes or where to connect to the controller.
- The last socket, behind all others in the photo with 3 wires (blue, red, and yellow) comes from the pedal, but I couldn't find which socket it should be connected to the controller.

The photo of the throttle;



And this is the wire description page of the controller;



In this photo, I put the wires which I couldn't pair in red lines. I have 3 sockets on the bike side and 6 on the controller needed to be connected.

I hope this explanation is clear enough to get some help.

Thank you...

Starting from bottom of list.
Green wires are phase learn wires, if the motor runs rough or backwards join them for controller to learn correct phase sequence. once motor is running , turn off and disconnect them. It may take several tries for the learn to work if not working correctly.
( Note if bike is running correctly leave these wires well alone and unconnected).

Brakes are for brakes sensors (non hall type) or reed type. If you have brake sensors fitted they liely connect th the blue/red wires. Follow/trace the blue/red to be sure.

cruise control enables auto cruising wthout pedal or throttle. Cruise = unsafe so disconnect the blue loop.

Get help sensor is PAS coonection , connects to black connector with blue,red & yellow.
Wiring order is black/yellow gnd, red/red 5v & blue/blue signal.

Brake light if rear wired light is fitted, usually vai a switch.

Electric lock/switch lock connects to the green/yellow of the throttle switch/button.
Shouldn't matter which way they connect as both have voltage power, all the button does is interupt the power supply as an on off switch.
(note the electric lock wires are looped to each other so indicates both carry voltage and is a switch wire).

Thank you for the information, Nealh.

Do you have any idea about which sockets of the bike pair with the controller's sockets?

They are in my post if one reads carefully.
