I was changing the brake lines on my car and found this vacuum line just laying on the plenum, can anyone tell me where it goes? its connected to the black cylinder in the engine compartment front left... here s a few pics...

Typically the line comes from one of the vac ports on pass side rear of the plenum to the one way valve you show.

Rear port of that valve goes inside to HVAC, the side port goes to the vac ball with (maybe ) a T off for the cruise control

 

im confused, the end that's not connected goes to the plenum or vacuum ball??

 

i seen a vacuum diagram on the board but cant find it, can someone post a link??

 

That line connects the plenum to the HVAC controls on the pass rear of the engine bay and in front it connects to the cruise servo and the vac ball. The little plastic piece is a check valve

 

ok, I think I see where the larger end of the vacuum line goes, on the pass side of the plenum are two large ports, one is in use and the other is capped. I followed the long vacuum line from the plenum to the vacuum ball, then it goes to the right to what looks likes something that has a brake line going into it... then I found one more line that's hanging, smaller than the plenum hose port....
so... I assume I uncap that extra plenum and connect the larger vacuum line to that but not sure what to do with the extra smaller one up front??.
hope I made sense, heres pics...

anyone know where this goes??

 

Does your cruise work?

 

The vac line you talk about is the one shown off the side port of the check valve in my pic above ( which gets vac from the plenum port marked HVAC in your printout )
and only goes to the vac ball ( with a T off the line to the CC if fitted to your car).

You have the printout of the purge system with you,
You will see the line in question from the check valve to the vac ball has no connection to any of the charcoal canister purge ( CCP ) components you are suggesting hooking up to

In fact that vac line does not even appear on the diagram you have , all CCP vac connections are as shown on the printout ;to the front , mainly to the TB

 

ok, kool , ill try and find the c.c connection later... I think I do have cruise control cuz I have a switch on turn signal switch that has cruise on it with a push button....
