Mostly plumbed (pneumoed?!?) up. Im like 90% the PO had it wrong, it now matches the diagram in the manual

That being said, there still is no matching port for the (as far as i know inoperable) vacuum driven cruise control, although there are two spare ports on the back, neither is of the large hose diameter. Also the hood is back on!

Still left on the engine: new dipstick tube, rear bolts on both headers, starter reinstall, wiring harness, new negative battery cable, accessories.
