Hey all just wondering if any body nows where the vacuum that come out of the front of the throttle body on an 84/85 T Type goes i know it goes underneath the throttle body and then has a steel line coming out and around back of engine but where it connects to i dont know. I looked at a couple diagrams and cant figure out. If anybody could please help i would really apreciate it. Thanks Frank

Here's a picture.
If it's the vacuum connectors pictured,they are for the coolant lines.
Most people block them off.
They run over to the metal line for the heater hoses on the passenger side.

yes thats exactly the one coming off the throttle body. Know i eliminated all my heating hoses and blower on passenger side so can i just cap that line off. and will this effect my throttle body. Thanks slow for the info. Later Frank

You can cap it off or just leave it as is.
It won't effect anything.

The map vacuum line hooks in behind the turbo.
There is a port on the intake with a tee.
Should find some info there.
Manuals are sometimes for sale on the boards.
