plinth

Hi all. Yesterday I noticed the neutral sensor cable on my 1998 Fi W is frayed. I'd like to replace it, but I'm struggling to locate a suitable replacement or even a part number. I can see the sensor itself using the CMSNL website, but it doesn't seem to show the cable. I'll attach a photo of what it looks like. The neutral selector and indicator is working fine, I just want to be sure it's not going to stop working because of the cable. Thanks
