It seems like every time I see a pic of the vacuum lines connected, they're ran one of two ways. Is there a difference between the 7MGE and 7MGTE's paths. Perhaps some are bypassing their heater cores?

Can someone please post a pic of their heater control valve with the vacuum lines attached for correct function?

Thank you.

Do you mean a difference between the 7mGE and 7mgte?
If so, then yes, there's a difference. For one thing, the GE has a vacuum resevoir, mounted under the intake manifold.
I'm not sure how the lines match up, going over to the heater vsv. Why not look at the diagram under your hood? It'll be
in the top left corner, where the hood closes next to your intake.

Yeah, that's what I meant (corrected). I tried looking at the underhood diagram, but it's hard to make out due to overspray :(

From what I've seen, the GE's heater vsv's vacuum lines from it's lower solenoid go into each other. The upper metal diaphragm housing line goes over to the intake manifold. On the GTE, the metal diaphragm housing's line goes to one of it's lower solenoids ports (inner I believe), and the other goes towards the intake mani.
