Resurrecting an old forum topic...........
Does the black vacuum hose connect to the upper or lower port on the vacuum controlled airbox thermostat?

Thanks,

Hey lee, do you know if there is a picture on the site of that hard to find vacuum line under the manifold. My wagon throws that CEL code that says O2 sensor 1 is bad but has been replaced. With my big hands I always break something else looking for leaks.

I don't have a picture but Justin does, hopefully he will see this and post it for you. His picture of it is with the intake manifold off but it shows the exact location.
