What are these 240D thingies?
 

I have some whatzits, does anyone recognize these?
First, on the driver's side fender, there is a round, single connectorAttachment 169246.

Second, beside it, is a connector with 8 pins. This is definitely electrical, but what?
Attachment 169247

Third, above the oil filter, there are two yellow vacuum lines which probably are supposed to plug into that plugged off y connector. What are these for?Attachment 169248

Finally, on top of the valve cover is what looks like a spare throttle linkage ball. Its position is adjustable. I don't have a linkage to snap on to it, and I can't see another spare ball for it to connect to. Any thoughts what this is about?Attachment 169249

Picture 2 - Electrical connector for (missing) cruise control actuator assembly (?).
Picture 4 - Ball end of connection for (missing) cruise control actuator rod (?).

Picure 2 - Connector looks like it has 7 pins...hard to tell as the picture is very small.

I think you're right, the connector in picture 2 does have 7 electrical pins. I believe the 8th is actually a locator stud, between the rows, to keep you from plugging it in wrong way 'round. Can't really make it out in the low res picture.

The cruise actuator is present, and it is hooked up. The cruise lever on the steering column is dangling loose, so I haven't tested it.

Thanks!
