Way through 2012 sedan firewall? - Toyota Yaris Forums

jn3825 · 12-23-2013, 07:39 PM

Is there a decent spot to get through the firewall on a 2012 sedan? I was trying to find one that i didn't need to drill but was unable to. Granted there was 8" of snow the night before and with the windchill at 5 degrees i didn't make the most thorough search but i did as much as i could from the top. Any help would be great.

I am trying to run a 4 gauge wire for an amp.

Thanks!!

Go through the giant grommet where the main harness runs through. If you look up behind the dash with your head by the brake pedal you will see it. The other end is right behind the battery.

Take a picture of the passenger side firewall and we'll circle it for you.

I went through the drivers door, no drilling required!

On my 2007 yaris sedan I looked for the factory hole behind the glove box , but for some reason wasn't there so I drilled a hole behind the glove box and ran wires down through the plastic pieces along the inside of the car under the door sills to the trunk where my amp is . Also did the same with the speaker wires and ignition wires because if you run them on the same side of the car it can cause interference.
