M110 switchover valve connections & vacuum problems

1985 280SEL. Spark plugs, wires, and distributor cap were recently replaced.

Engine and trans were swapped from a 78 280SE euro. Whatever is missing from this photo was taken from the original engine:



The car dies when hot and idling with the A/C on and in gear. Switchover valve suspected, and it's not even hooked up.





Where do these vacuum hoses hook up to?


A few other vacuum maladies:

This is not hooked up to anything.


Nor is this:


This is plugged:



A few more details: Cold starts are immediate, hot starts require giving it some gas. Seems to be running rich and eating fuel excessively. Has a misfire every few seconds MOST of the time but not ALL the time.

Any guidance on these issues would be greatly appreciated.
