Installing the vent & fan was fast and easy
Places the vent where I wanted it on the outside, then tried to picture where that would be inside. Adjusted. And once I was happy, I marked the cut, and drilled some holes.
I used snips to nibble the cut out pretty quick
Then used some self tapping screws to secure the vent
Added an oscillating fan inside high in the corner and wired it into the electric panel
