I have a 1981 porsche 928 and while replacing the heater valve noticed a loose vacuum line not attached to anything. It has a broken fitting end which is making locating the unattached fitting extremely difficult. This line runs from the top of the dist cap to a T that branches 1 line throttle body near air intake and the other to an unknown location. Any assistance establishing where this is supposed to go would be greatly appreciated.

Vacuum line at dist cap

\"T" at intake

\"T" at intake and line connected to throttle body.

Unkown vacuum hose coming from \"T" with broken end. I need to know where this is supposed to go.

Look on passenger side head. There is a theral valve that gets broken frequently. It should have 2 lines on it.
