This is an original piece taken off a 1968-1972 Chevelle/Monte Carlo. I am not sure on the exact application of this wiring piece but its a multiple wire accessory plug of some sort. I think it may be for under dash courtesy light or possibly lighter mirror but I'm unsure. The wire casing has no splits in it only slightly worn and dirty. The connector pieces are a little beat up but are still usable. Its just shy or around 24" / 2 feet from end to end of each connector piece. The diameter of the wire is about 1/8". Message me if you need any other measurements or pictures that I can help with.
