Fuel Level Not Indicating And Odometer Not Advancing

In an effort to rectify some issue my husband and his friend cut the wire above the clutch cable on the clutch perch on my 2013 Tiger 800XC ABS. Since then I have a few issues as mentioned above. At one point I somehow found an article stating that wire has multiple purposes, and I deduced it was likely my problem. However, I can no longer find that article, and I cannot find anywhere what that wire is called. Microfiche does not even show it. Can anyone enlighten me? Much appreciated for any expertise you can share on my particular bike!
