Hey Guys,
I decided to take a few extra pictures while passing the power cable through the passenger side firewall. It didn't take me long to figure out which hole everyone talked about, but it seems that a lot of people are still asking the same question. So maybe this will help out a few new guys.

Step 1:

•Pop open the hood:
•Disconnect battery


Step 2:

•Open passanger side door
•Remove the passanger side dash cover.

I just used my finger in the top right hand corner.


Step 3:

•Locate the hole that you can see the yellow foam in. Use a pencil or screw driver to push through the foam.
•Push straight toward the front of the Jeep.

As you can see in the picture, I used a wide/long screw driver.







Step 4:

•Use a metal wire hanger or a long ziptie to put through the hole you just made.
•Once you see the hanger/ziptie come out the other end, use electrical time to attach the wire.

It doesn’t matter which direction you run the wire, but I ran it from the front of the Jeep into the dash. (I’m mounting a fuse panel behind the glove box.
If you plan on running the power wire for your amp, it might be easier to pull it in the opposite direction. (since you won't have to pull as much cable through)





Step 5:

•Gently pull on the hanger/ziptie until you see the power wire coming through.

I ran a 6 gauge wire for my fuse panel
Now you have to decide which way you want to run your wire. I tucked mine to go inside the dash and behind the glove box.












* AGU Fuse Holder & Fuse. I bought it from Ebay User: "trucktunes". (Received within 2 days of payment.) $3.59 total
* 20 feet of 6 Gauge power wire bought from Ebay User: "ennis_electronics_151". (Another fast shipper) $20

Thanks for the write-up. Very timely for me.
I will be running a #4 wire to the back for an inverter and aux power outlet.

Great detailed Write-Up but you keep mentioning a car, I only see a Jeep

Corrected!

Nice writeup. i am going to hook up some lights soon, and this will be a big help.
Thanks

Good write up. The JK is by far the easiest firewall to get through of any vehicle I'v worked on. Try running a wire through a firewall hole in a cramped import engine bay, thats sealed with two rubber boots. You practically need to rig up a knife on a stick to punch a hole through it, and pray you don't slice the wiring harness to the PCM

I used the same spot to route power to an auxi light switch in the cab, but I used corrugated plastic conduit to protect the wire.

That wire's hot, not unlike a light bulb filament... nick the insulation somehow and you have a potential fire.

FWIW

Nice mod, but your mistake killed a kitten anyway...

Does the same deal exist on the drivers side? I see the same hole with the foam insulation, but I'm reluctant to push through if it's not open through to the firewall.

If you are saying the wire you routed gets hot, the wire is too small for the load.

A relay, with the control switch in the cab, would be a better set-up.
