Still trying to get a power wire through firewall..

[LtNoogie]

I paid a stereo installer $40 to drill a hole through the firewall under the dash and put a 1/2" grommetted hole there. I am able to run two 4gauge power wires, and three sets of wires for gauges.

It was a very easy $40 to part with considering how fast he got it done and how I had no clue how to do it safely.

That's what I'll be doing when I have to start running all my power wires. I don't get why everyone is torturing themselves trying to find ways to run wires. Pick a spot where you want the wire to go and punch a hole in it (as long as you know what's on the other side!)

Damn man for like 50 bucks you could have gotten a sub and amp installed as well. 40 bucks sounds steep for just a hole but if you're happy then by all means.

Would you please include a photo of where the hole was drilled or add a detailed explanation of WHERE the hole was drilled? I'm assuming the hole was drilled from the firewall side into the passenger compartment.

Finally, I'm through the firewall on the passenger side; I used the grommet hole designed by Toyota just above the ECU. I'll add detailed instructions on how I finally got through & include annotated photos this weekend.

I had to go to a junk yard & look at wrecked Yaris that had the engine & ECU already removed. When I saw the grommet/hole in the firewall I then knew what to look for from the engine compartment & from the passenger side under the glove box.
