Hi all, I was installing my radar detector and jumping off the power from cigarette lighter when I saw this cable. It's behind the radio/temperature controls. It wasn't plugged in to anything, just taped to another wire.

It's the one in front of the one with the white table on it.

Any idea what it is? Thanks

 

my o8 has a plug there to,but mine is for the trailer brake controler.if that helps?
