I just pulled the coolant and washer tanks to fix the blower motor resistor (yeah... now it works at all speeds!). But while down there, I found two things just floating around, connected only at one end, and wonder if anyone can help me figure out what they are?

This is a 1996 Ranger XLT, v6, 4.0L, manual, 4x4.

The black ball is vacuum storage, the line thats in your hand should go to the vacuum tree on the manifold and someway connect to the vacuum storage.. The vacuum storage on most vehicles is used to run the vent doors and such in the cab for heating and cooling. The electrical plug looks like (but may not) it goes to the Air Intake Temp sensor usually somewhere in between the air filter box and throttle body, usually the duct that connects the 2. I'm not 100% sure. Someone may chime in that can confirm.
