1996 sonoma, wire through firewall?

How can I get thou the firewall from the battery to the cab in a 1996 Sonoma / S-10.

Want to use one 4 or 8 ga. for thee amps. 2 small and one not so small.

Automatic or manual transmission? If it is automatic, there is usually an open space where the manufacture would have routed the clutch cable. I have not done one of those in a while, so I don't know of the best place off the top of my head. If you don't see a good place, and you are not 100% sure that you won't nick a wire, cable, or brake booster, then spend a little cash at your local install bay and save the money of replacing a wire loom or brake booster.

You should be able to find a factory grommet through the firewall in the passanger floorboard... It is for the antenna for the radio's wire.. I snuck my 4ga wire in that grommet with the antenna wire... it find it pull back the pass side carpet in the front, you'll see it... it pops out kinda underneath about 1.5 ft below the blower motor... Good Luck!!
