Look under the hood on the firewall. Toward the top left of the brake booster you will see the wire (mechanical not electrical) that controls your climate control temp. That wire goes through a black rubber grommet. Carefully poke a small hole through it and run a piece of test wire through. Go inside the car and look under the dash on the drivers side above the gas pedal on the firewall and you should see the test wire coming through. This has worked for all three of my LS's and should work for you.

OR...... if your running it to a amp in the trunk. Just run it under the car all the way to the rear spare tire well. There are these plastic sleeves that have the fuel lines in them and have plenty of room for a heavy power wire. Much easier than running it through the interior. IMO
