First, let me just say thanks to all who have replied to my continued questions on this forum. It's been a invaluable resource while working on my 68 Malibu. Now the question...whats up with this wire???
Mine plugged in just below the rear window on the left side on my 70, orange wire just like yours.Scott it is a trunk light like the posts above. Look at your rear harness on the drivers side towards the tail pan and see if that wire goes to a plug there. If so its factory.
X2.I think there is supposed to be a clip that keeps the wire attached to the hinge.
