This is from the door to the utility room, just below where the cable enters the space. The other side of this wall is the crawlspace. Tomorrow's job will be to find out how it's routed in there and then begin pulling the old cable out with a new pull string attached. I'm sure I'll have to make a few more holes, but installing the new cable *should* be pretty straightforward. (The yellow rags I was using to wipe sweat and drywall dust off my head.)
