Just out of curiosity, since the Tesla has the power port on the driver's side, are you backing in and running the cable to the left (along the wall) or are you pulling in and reaching the cable around the back to the other side of the car? Did you get the 8-foot, 18-foot, or the new 24-foot cable? And is the gray box just a junction box or is it a service disconnect?
Looks like a clean installation.
