I have a vac diagram under my hood that is not helpful, since I don't have all that stuff on there anymore. It's weberized, too, and doesn't have the Christmas tree of hard lines and other extraneous vacuum crap that came with the hitachi.
Question: What components do the ports on the Thermo Vacuum switch terminate at? Which ports exactly on the thermo vac switch?
I've done a lot of research on this, but can't find anything specific enough to say, for example, the top port leads to the egr, middle to the charcoal canister and bottom to the carb egr port, or what ever it is. I'm looking for a definitive vac signal path please. Thanks.
