I ran my 4ga thru the passenger side just look for the rubber grommets. And pull down your glove box you'll have to use a coat hanger and tape the wire to it and pull it thru...I'll take a pic later when I get back to the shop.

Also on driver's side by the steering column there is a gasket with other wires you can piggyback on. Did that for my KC lights so the switches would be on my side.

Just behind and to the right of the gas pedal, there is a rubber plug in a hole ready to be used... the carpet is already cut out nicely too. (2010). Make certain you are careful not to leave any wire hanging loose in that spot though. lol!

I've always used the grommet but the steering column, under the master cylinder area.

If you have the 5.0 (and assuming the eco is the same) there is a gromment on driver side firewall already there for the picking! Little nipple on it that cuts off and leaves a nice hole. Had to expand hole a bit but got a 0 gauge wire through. Here's a picture...
