Another option depending on your skill set is to open the wall, drill the hole, fish the wires and repair the hole.
I like to use a 6" hole saw or pot light saw to open up the wall a foot or so from the floor. The hole will need to be big enough get your drill in with the bit to drill the plate at the bottom. This will let you look for wires, and cross bracing. When complete, I cut a piece of 1x2 that is a few inches wider than the hole, maneuver it into the hole and attache with 2 dry wall screws though the wall into the wood on both sides of the hole. Then place the round cutout piece in the center and attach to wood with screws.. I normally fill the crack with Liquid nails let it cure for a few days and finish it off with setting type drywall compound.. prime and paint..
Yep, lots more work then drilling from the basement.. but if you do not have access below this method works very well.
Another trick if you are going though a wall that backs up to a closet or other out of sight area (behind fridge maybe) is to buy a plastic access panel and cut a hole the proper size for the panel. When done, glue in the panel snap on the cover, done.
I would expect neither of these options are helpful for you purpose but maybe to someone in the future who is doing searches.
