I'm not sure what you need to see. I snapped this on my phone so the quality may not be the best. Let me know if you need another view or more info.

The thread is setting on the plastic cone which came with the machine on the right thread pin. It leaves the cone and goes up to the telescoping thread guide. The thread passes through the right hand hole of the thread guide from back to front.
