Replacing the speed sensor unit EW-SS301

[LeMec]

I unfortunately got a branch stuck in my rear wheel of my Rise H, resulting in damaging the rear speed sensor unit, and the w101 error.

Anyone replaced these? Looks like the wire partly follows the rear brake hose, which leads me to think that I’ll have to drop the motor and the battery… had to do that a while replacing the rear brake, and it wasn’t fun!
Any easier way to replacing the unit? Also it doesn’t seem like the connector would fit through the internal frame inlet/outlets…

As a follow up on this.
I did find additional information as to how to install this, on the Orbea blue paper page 90. Cable connects to motor.
Also, it requires 760mm length cable.
Any input from where these can be sourced?Seems like it is out of stock in most places.
