I have ran wires from two spots on the passenger side. One grommet right below the air box, and one in the wheel well. The one below the air box come out pretty high up into the dash, you will need a coat hanger and have to get the downward angle right to fish it out. The one in the wheel well comes out behind the metal plate on the floor board. I couldn't find any where good on the driver side.
Its pretty easy to run wire in the valley going between the fuse box and air box and have it be completely hidden.

I found that if you take off the under park of the drivers side dash and look at the back theres a nice grommet going right into the drivers side fuse box. I did my AEM wide band through there, to make it easy I removed the ecu and then took a small coat hanger and fed the wire i wanted in there to it and pulled it right into the fuse box keeps things nice and tidy.

Best way to see the hole it remove the ecm an ull be able to look down an the wires go through the fireway nice big hole. If u shine a light through there u can see the access port on in the foot well with that lower cover removed simple. This way no reason to run a wire all the way over the other side an stays nice, safe, away from liquid, an looks good

If you open the fusebox you wiull see the engine ECM inside next to the fuses just undo the the connectors and pull it straight out and place it safely to the side while you do your work
