Firewall question
^^ yeah
try removing the nuts holding the pcm down (passenger side), then move the pcm over a little and feel back there. you'll feel a good sized grommet with some wires coming through.
from the inside of the car, remove the plastic piece under the glove box as well as the trim on the right side. while kneeling on the ground next to the passenger seat - reach up along the right side of the firewall and you'll feel that grommet.
just make sure to seal it off or keep the grommet there or you'll get some extra noise coming in down there. i got so much **** going through that grommet, all i use is wire loom to seal it now (not recommended).

If i remember correctly you could fit a 1/2'' line through there with no problems, also a perfect spot to run wires for a shift light, and make sure to go through the grommet and not just leave it out, otherwise the metal on the firewall has a tendancy to fray things
