The hard part is outside. Needs to be weather tight. Use a conduit through the wall, into a weather tight junction box on the outside. For each cable, open a hole in the junction box and install a “cable gland”. A cable gland is a device that seals around a cable, fits through a drilled hole with a rubber washer, and is weather tight. They sell lots of them on amazon.
