It's kind of a bad picture, but it's a hard plastic line that is routed in my "wire tuck" lines. It's some sort of vacuum line I'm thinking. It goes from a port right near the PCM and seems to go towards the battery area? Anyways....it was very brittle and when I moved it around it broke. Just curious if I can cap it off. Thanks in advance!

Yep, I believe that's the same one. I'm not sure either, but the car still seems to run ok. Just curious where it goes....

It's for the HVAC system. Goes from the reservoir on the passenger side frame rail up to the check valve near the PCM.

Oh ok, my HVAC is long gone lol. So I assume I can just cap it at the check valve near the PCM?

^^^Even your complete HEATER is gone, core and all (TOTALLY trailered drag ONLY car??)?

Because, IF you still want heat in the car that tube has to be connected, or the HVAC heater switches will not work.

My AC is gone too but I still have the heater so thats why I left mine plugged in.. (tucked under with the rest of course)

The vacuum source is for the directional doors in the HVAC box only. So if it's gone, all that stuff can go. The only thing you need is a vacuum cap on the intake where it used to be hooked up.
