Need help on a loose hanging wire

[Sanjazz]

Hi I recently purchased a salvage model y it came with a loose cable I’m unable to find the female connector it connects to, can someone please help, the big socket shown in the picture goes into the front bumper but the cable that I’m holding I couldn’t find where to connect
