I had the #43 couching foot that I kept when I traded in my Bernina 200E for my 830LE, but the wire gadget to guide the thread didn't work for the 8 series. Today, I bought the wire guide for that foot for the 8 series, but it came with absolutely no insturctions,

and it's a puzzle to me how to put it in. Does anyone out there have this installed on their 8 series machine? I can't even tell which end goes in the machine or where to try it. I did an Internet search to try to find the answer, and all I get are videos and discussions about the foot itself.

Help, please.
