The filament for my Ultimaker 2 is stuck in the Bowden Tube - it does not reverse. Although I can remove it from the print head, I have no way of removing the filament from the tube. (See image below)

To make matters more complicated, once I took apart the print head (I was concerned it was somehow related to the PFTE coupler) I noticed that there is a disconnected wire within the print head. I looked around but I don't know where the wire goes and how to reattach it! (See image below)

These may be unrelated issues but I suspect they have some connection. Thanks for any help.

So this is an extra wire that is in the head. It's not used for the moment so you don't have to worry about it.

Be carefull not to pinch any cable when remounting the head.

Did you manage to get the filament out of the bowden? Was it stuck because it was grinded?
