What year? in the 606 it looks like the one rigged up to the resonator flaps.

sorry, its an 84 turboD, there seems to be a line missing, which line is that?. i plugged the "T" fitting as a temporary fix.

Thanks

That one looks like it goes to the "black box" on top of the valve cover and to the EGR. That setup can be totally bypassed. Plug it like you did, as the 3-2 valves in the black box are a great source for leaks.

Based on my 82, that tee directly connects to the "side" of the white plastic device on the IP, you can see it in your photo. I can take a photo if you need one.

If my memory serves me correct black lines are vent lines.....

Yes, the black line that is connected to that tee is the vent line under the dash. However, the other tee connection is attached to the "vacuum control valve" on the IP (number 65 on this diagram):

I believe it is just a vent, the black line that goes through the firewall is actually open under the dash. It should be connected to the tee so the vent is open to the clean area under the dash instead of the engine compartment. Having it disconnected probably wouldn't change the way the engine runs.
