hey guys,

was cleaning out my valves and checking the over all condition of my "new to me" 2011 35i.

I'm putting her back together and found a plug and what connects to it.
So dose anyone know if there is a connector plug for it or dose it just stay open?

It has dust on it that seems like it doesn't.

It is located right next to the fuel pump on a clip.

Just want to be sure before I put her back together tomorrow.

Thanks in advance guys!
And sorry for the huge pics...
