    What passes thru this hole in the firewall?

    Hey hey - so Ive got an M52 swapped car that Im sorting out (bought it swapped) and the guy stripped a lot of the interior/creature comforts out of it. This led to pretty much all of the holes in the firewall being left open/unsealed and Im picking away at them so it doesnt leak.

    The one I havent figured out yet is on the passenger side, RIGHT next to where the battery cable from the trunk comes thru, except more towards the outside corner of the engine bay. I dont have a picture of it right now but its an oblong/semi triangular kind of opening a few inches long that is wide open on my car. What typically passes thru here? Ill need to block it off somehow and was thinking an oem grommet might be a good head start, since whatever it was that went there I no longer have.

    Sounds like the hole for the A/C lines.

      I agree.
      The car makes it possible, but the driver makes it happen.

        Makes perfect sense, I have no AC (yet). Thank you!
