Re: wiring thru the firewall

I'm not sure if it voids the warranty, but here are two ways I did it or a rubber boot you can use for varying number of wires. Yes, it's on the driver's side where the main wire loom enters the FJ. You can see a portion of it in the photo below on the bottom edge. It's easy to pass wires, you just have to cut the firewall insulation. I cut it first, then drilled. I only cut 3 sides of it to create a flap so it's still attached.

The smaller cable gland uses an exisiting hole I enlarged and the larger cable gland is a new hole I drilled, both with a step down bit.

Yes sir, I'll try and find a better picture.


I needed the girlfriends help to push through a 4 gauge cable for stereo\amps and it only took us about 10 minutes but something flimsy\limp like a skinny cord may be more of a challenge.

good luck

Here's a better pic of the firewall hole

Instead of just flat out removing the black rubber graumet drill\cut a small hole in it so you can run the cable through it and put the gramuet back in if you can.

If you have cheap a wire puller or a long screwdriver or something like that you can push it through from the inside, tape the wire to the puller and give it a lil tug. I have 1/0 awg, 2x 8 awg and a bunch of smaller wires running through that grommet. You should have no problem.

Then if you pull out the glovebox over the steerin wheel you can easily route the wire up and over the steering wheel or to where ever you are mounting it.

Re: wiring thru the firewall

For my amp power, I just poked a hole in the existing rubber grommet on the driver's side, adjacent to the existing cables. Then pushed the cable through and sealed with a bit of silicone.

thanks
