I have actually see this this truck on the road My local news did a little story on it.   http://jalopnik.com/5905431/virginia-dmv-revokes-f-osama-license-plate

My car is a 1986 Starion all stock   Found this on the drivers side firewall what is the box and vacuum solenoid?   http://i1231.photobucket.com/albums/ee501/Fiorness/2012-04-26_17-09-37_238.jpg   I noticed that one of the vacuum lines was not hooked up and was wondering if it is necessary? If so what dose the unhooked line go to?   Thanks for the help Steve
