Firewall rubber grommet locations? (Passenger side)07 Escalade

[Cleandenali31]

hopefully a post like this isn't too common, if so I apologize in advance. But I'm looking to run a power wire for my subwoofer. My battery is on the passenger side against the firewall. Are there's any existing rubber grommets on the passenger side firewall to get through under the carpet? Or close to the passenger side? Thanks

Nope, drivers side by the column...at least on pickups and my 13 hoe its there

On the pickups for a plow package hookup there is a hole with a grommet for plow controls etc. i found same hole on my '13 hoe but with a few wires thru it. Untape the end push your wire thru then tape it back up. I assume most of the firewalls are close to the same. The pic in my first post is off google but u get the idea. I wouldnt cut a new hole in the grommet but thats just me.
