There's a large rubber grommet up under the dash...I can't remember what OEM part goes through it, but that's what I used to run several things through the firewall. I'll take a picture of it in a bit and post it.

It's hard to miss...if I recall...it's up under the dash almost directly inline with the parking brake...it comes out in the engine compartment below and behind the fuse box.

Get and ice pick and some duct tape...tape your wires to the ice pick and poke it through.

Works like a charm.
