I wasn't sure wear to put this so I put it here because I see it as a body issue and an interior issue. When the previous owner did the B swap in my EF hatch they removed the AC as well as the grommet were the AC pipes ran through the firewall and used this spot to run wires for the MPFI. Is there anyway to fill this in? Do they make OEM sealed plugs? When it rains water runs down the firewall and in to my interior and pools on the passenger side. I actually took my carpet out because of it. (Makes it a lot easier to clean up.) If i get it fixed up i might consider putting a new carpet in.
