Not quite clear where you are looking. On earlier SC's the throttle body itself had a coolant line/hose, which a lot of people by-passed, particularly when adding the larger BBK TB. At the other end near the MAF is the pcv hose (like 1/4" dia) which connects to a stub under the main rubber air intake pipe. The other end runs along the front of the supercharger, changes to a hard plastic line and finally goes into the top of the driver's side valve cover. Everything else at the upper/TB end under the intake pipe are either fuel or a/c hoses and shouldn't be loose or disconnected.
Hope that helps,
Jim.
