Where is the best place to wire 4 gauge power wire through the firewall in my 3rd gen? I would like to avoid drilling if I can. Pictures are always welcome

 

if you take the left front wheel off and then remove the fender lining you will find a group of wires going into the car, this is where I took my wire through when I had my 3rd gen, 4 guage wire. You just have to make sure to take your time and not force anything.

 

Yep. Exactly. That's where I have my 4ga wire going through. It can be a pain, but as long as you take your time, there should be no problems. I think Craig Brace has a pic of exactly WHERE you go to. Look him up!
