How to: Firewall access for 4ga wire

Vehicle: 12 Sky GS Hatch, non-Bose with 6 speed manual.

After much researching, I've found that there were several potential areas to run a 4 gauge power wire as listed below.

1) Below steering shaft. I couldnt get it open enough to even try fitting a large power wire in there. Risk of water leaking in.
2) Using grommet for hood release. a 4ga would probably fill that entire spot
3) Utilizing AC/Heat lines located behind the glove box. I didnt even attempt this. Too risky being close to those lines.
4) Main wire harness behind the wiper motor. I didnt attempt this as i Had already tried 2 others.

Here's my solution:
On the passenger side of the engine bay youll see a circular outline. There is nothing even close to this location. I ended up drilling through this area (full glove box must be removed) from the cabin into the engine bay. I put in my own grommet and sealed the grommet with RTV.

Heres the pics for future reference:

Mods can you change the title to include years or generation as to not confuse users

Pretty much you can buy any size grommet that will accommodate the wire you want and then drill a hole to size.
Ideally you would have it slightly lower than the glove box for easy access, and behind the heat pad/mat in the engine bay.
