IP vacuum ports
IP vacuum ports
Could someone tell me what the different vacuum ports on my '85 IP do? I pulled all the vacuum stuff out and want to start from scratch and keep it simple. I understand the ALDA, but why the two connections on it? I can eliminate one, right? Which is the shutoff? I have a diagram, but it doesn't show everything and it certainly doesn't tell me what I can remove.
A is boost to ARV
B is boost from manifold
E is shutoff valve i think (not sure where it goes.
C is vac vent from cabin
D is either from the main vac line or to the trans cant remember.
That's what I thought, but "REALLY bad" made me think something worse would happen. Like mechanic damage or something.
