Got a connector with nothing plugged into it
 

Theres a 2 pin connector hanging off my frame near where the ignition coil connector is. Its a 2 pin with black/white and pink/black wires.

What does it belong to? I can't find it in the wiring diagram.

There's an extra plug kinda by the seat (I think it's the one you're talking about) that's used for plugging in diagnostic tools.
