Questions about Sinar shutter cables

[Songyun]

The cable that connect the shutter and the rear frame. (It closes the shutter when you insert the film holder) Are there two versions of them? I have one cable, but I can not mount it on the rear frame.

there's a fitting that screws in to allow the bayonet to latch in, if you download a copy of the sinar catalog, you'll see them ilsted.
