Help Phantom cable

no idea what this is and why it's disconnected ? Ahaha cannot trace the wire does anybody recognise it, has been like this for along time.
Bikes been roll starting everyday for about a month tryna find an electrical issue as battery's alllllllllllgood.

 

i think it is the fuel sender unit wire that goes to the petrol tank.

 

Flux capacitor ?

 

Hi,
Have you guys finally figured out the cable? What was it for?

 

Maybe this loom is also used on other brand's / model's , hence being this loom connection not used.
Does your fuel gauge work ? , as risky has commented on.
