Had a mare with mine today, figured out eventually, anyone got any tips or am I missing something?
I used a piece of electrical cable sleeving to form a route through from motor area, didn’t drop motor, just the battery.
i only wanted to shorten the overlong cable and it turned into all afternoon of a job, original cable frayed when I cut it, luckily I had a spare.
I just dropped battery, removed cable housing from hole, fished cable with knurled end through hole, grabbed cable with one of those long bolt grabber tools and pulled it up through seat tube.
