87 TBI vacuum deal on manifold?

[2_wacko]

There is a deal on my manifold with 2 vacuum lines. The one pointing up go's to my trans and the other points back towards the cab where does it go.

My guess would be that the other fitting goes to the vacuum ball possibly (this is a vacuum resevoir that controls heater door functions and I think cruise control).

if this is all stock, you should not have ANY vacuum lines going to the trans...

typically on the TBI setups, the brake booster lines uses a hard, threaded line right to the base of the TBI unit also.
