Can you describe the problem(s) you’re having with your bike? Do you have a reason to suspect the wiring? Usually, that’s low on my list of likely failures that I hear about here.

The round water proof connectors used on harnesses are pretty good defense against corrosion, Sometimes owners will use zip ties to dress up cables, and if they are too tight, they can stress/break wires inside the cable,

Motors/controllers will overheat and fail if you beat on them. I've have several controllers fail, but all were due to water getting inside. When you open up a controller compartment and find the controller box in a puddle of water, that's not good,

There is a systematic way to approach a dead bike. Check for power, Does display turns on. Does it show speed if you spin the wheel. Does the wheel spin freely by hand. If the display had brake indicators, do they fire when you squeeze the brakes. And then there are voltage checks,

Prior to tariffs, best place was aliexpress for controller/harness/display. Now amazon might be the same price. You'll probably want something that fits inside where the old one fits. Might limit what you can buy,
