Main Wire Connect For Jansno Electric Bikes

How to Choose the Correct Main Harness for Your Jansno E-Bike

Q: How do I determine whether I need a With Lock or Without Lock main harness?
A: Simply check your throttle.
* If your throttle has a keyhole, you need a With Lock main harness.
* If your throttle does not have a keyhole, you need a Without Lock main harness.

Q: Why Choosing the Right Main Harness Matters?
A: Since the main harness connects the controller and the turn signal switch, selecting the wrong version may cause compatibility issues with these components.
