Where to run Power thru Firewall

Rainwater will lubricate the grommet and help the wire slide easier.

What could possibly go wrong...

I used the grommet that the hood release cable runs through. I got both 4 gauge wires through with ease.

I thought about that one.
Ended up going with the "big" one up and to the left under the dash.
