Wiring hanging near wheel well ?
 

After a long drive I hopped out the car and noticed a strand of wires hanging near my driver's side wheel well. What is this and how would it come loose​​​​​​​

Picture of wire

If this is on an F-Body, it's not a stock device.

Yes, its an F body 99 LS1. I did some more digging where its hanging and it looks like its going up near the headlights. I dont know if its a spare/extra wire but its a four pin wire.

Another closer picture

You need to find where those two wires go and what they tap into. It's definitely for some type of aftermarket accessory someone has removed.

gotcha

Looks like it's for halos or something like that. I had them dangling for a while.
