Didn't realize this was happening until a recent tire swap for spring. My boots were making contact with the wheel connector & wearing it down. Fortunately damage seems to be only cosmetic.
Rerouted the wiring so now it's to the inside with the derailleur cable sitting outward. I use a wire for the last attachment point for the motor cable alone so it can be removed without having to cut a wire tie.
Also experienced chain jump likely from chain wear after 1000 miles that ended up sucking gouging the chainstay a bit & cutting into the motor cable. The wear seems a bit premature, but probably a combination of low end chain plus salt/slush/snowy winter. I replaced with another KMC chain, but a step up with the X9.93. Again fortunately the damage seems to be limited to the outer cable & no wires were expose. Was able to fit heat shrink marine tubing over the area & sealed it up. The new cable routing should help avoid this in the future.
