Well I found the disconnected connection and all the issues were resolved (ignition, locks, lower vents). However, I also found (or may have disconnected while looking) another vacuum line, which I'm fairly certain went through the firewall into the area under the dash. It is now disconnected...however everything (that I know of) seems to work fine....hmmm?? As always thanks for the help.
