Where To Run Wire Through Firewall?

[bendsley]

Just looking for a good place to run a wire through the firewall into the cab on a 08 GMC Sierra.

Thanks, Brent

There is really only one that will work that is existing, thats where all the central wires run on the drivers side, just be VERY careful you screw those wires up and you are screwed! what are you running the wire for?

I ran my Sirius antenna through that hole. It was not easy to say the least. Do yourself a favor and just drill a new hole and add a grommet from an audio shop.
