I like to install an outlet on an exterior stucco wall so that I can
put in a fountain. The other side of this same wall is in my garage.
There is an existing outlet in the garage right where I plan to
install the new outlet, but the existing outlet is about 3' higher
than where I plan to install the new outlet outside.

1. Should I cut an opening on the inside wall right where the new
exterior outlet will be, and do I need to install an J box here?
2. How do I drill through the stucco wall? With a drill bit?

Thanks
