I am wiring an amplifier in a 1994 2dr ranger. Where is the hole in the firewall to fit the wires through?

 

Use the grommet around the steering column. That's what I used. It is a lot less of a hassle to get to. I have an 03 and I couldn't find a hole so I stuffed my wiring through the steering column and spaced them apart enough to avoid having to use caulk to seal any gaps. I was able to get three 8-guage wires and two 14 guage auxillary wires through it with no gaps.
