Is there an existing hole in the firewall to run a vacuum hose through for a boost gauge?? I found a grommet up top and I tried pushing a coat hanger through, but there is a wall behind it. Any help would be appreciated.

Yea Where the main ECU comes thruogh the fire wall go through that grommet if you want or go to an car audio installer and see if you can buy a grommet from him.
What about though the big wiring harness on the drivers side of the firewall? Behind the cruise control unit I drilled a hole for my 4awg stereo cable...that could work also...
