Wiring through firewall

Whats the easiest route to get wiring from my rocker switch through my firewall on my 2000 wrangler? I know there are other post about this but seem to steer clear of actually finding a good and easy point to get throught the firewall. I am probably retarded. Help

There's a grommet you can go through adjacent to the brake master cylinder, isn't there? That's where I ran all my wires in-out of the passenger compartment on my '02.

I have this one here but on the inside it looks like I have to pull the fuse box and heater stuff to get to it

And that looks like a three hour job in itself just to pull wires through

Now this is the grommet I think you are talking about but it's on the drivers side, probably could do there just alot more wire huh?(cause battery is on other side)

Yup, that's it; I'd hardly call it a "lot" more wire to run the wire there, maybe 3' or so at most. Easy, drops right into your hand inside the cab, and you can easily pull the lower dash panel to neatly run the wires to their destinations!!

Cheers, it's actually on the drivers side on mine and battery is on passenger side so adds about 5 foot of wire, but well worth that versus tearing out everything on the other side near the battery

If you have the 5-speed manual transmission, there is a rubber grommet hole plug located just above and to the right of the gas pedal you can drill a small hole through and pass the wires through. If you have an automatic, that opening is filled with the transmission's shifter cable.
