Hi,

I was replacing the brake app sensor under driver dash and when I pulled out the panel there was a long wire that is NOT plugged in. Not sure what it is or where it needs to be plugged in ? It's a black wire that looks like a head phone plug end ( L ) ???? Any ideas will try to post up pic.

 

 

Only thing I would see it being is an AUX cable lol
Maybe the previous owner installed it?

If you haven't already, just plug it into your phone and play music and see if it works :o

 

Any else ???

 

What OP said. My guess it was used for radar detector external speaker.

 

not stock wire.
aftermarket.

what the other fellas said.

 

trace it to the other end!
