Used to one around here somewhere. There are usually 2 lines that go to the interior, on is the vacuum feed, from the engine, the other goes to the heater control valve. Sometimes there is also a canister. The color codes aren't always the same through the years of the g-bodies either. Can you tell us how many plastic vacuum lines are going through the passenger side grommet of the firewall?
