Electrical wire hanging out the back

Is the "blue ended wrapping wire" also white??

Yes they are both the same white colour.

@Yendor: The wire is still connected on the back of the brake light socket. I've tried Silicone spray which did free up some of the rust.

I would do as pod suggested and just trace the wire you might even find the cut wire on the left is the same @ the tow bar.

Can't see it in the pic do you have a trailer plug on it?

Hook a trailer up and if all lights work and after you fix your other light problem................pull the wire out.......obviously it does nothing

You could have 100 wires doing nothing in your rig, depending upon what gadgets previous owners have installed
