I wonder if the po might have ran a new harness to the rear and left the original in place for some reason? And maybe the 3rd socket on each side goes to the side marker?

KMCAMPBELL

these are the three sockets, same on both sides

KMCAMPBELL

no, the side marker light sockets are there too

Probably had 63 impala-ish triple taillights at some point.

KMCAMPBELL

no i don't think so, I know the original owner of this care and the second, who was a young fellow who ended up in a wheel chair, so it sat since 1999. the wiring is original. But why is there 3 sockets? If i need to , ill call and ask him if he changed teh rear tail light wiring , but its highly unlikely.

Are your tag lights hooked up?

KMCAMPBELL

Yes, they are there too, just hanging but both are there???? still wondering,,,,,,

I see two wires. My guess is those are the original backup light sockets, and a PO ran an extra socket in parallel to the brake/turn/tail light on each side to get the 1968-style lights. That is exactly what is under my car now, I haven't cut the sockets and spliced in LED backup lights yet.

The wire color should coinfirm.

Original '74 tailight lenses did not have the two mounting screws visible on the outside. They were mounted in the bumper covers from the rear. I see in your pictures that there are long metal(?) screws coming thru the new bumper cover. It seems that the PO installed later tailight lenses that mount from the outside on the car. '75 lenses mounted from the outside so screws would be visible, the bumper covers changed in '75 to a one piece from a '74 two piece. Maybe this has something to do with the extra original white bulb socket wire? . One would think there would be four white socket wires hanging back there though. Maybe if you check more closely you'll find that they might have cut one original wire on each side and then spliced into it with the new black plastic bulb sockets. Sort of what"bikespace" is thinking above!

Just some food for thought!

I believe that Bikespace is correct.

Some took out the REVERSE lights and wired in sockets so the car has TWO turn signals/brake lights pre side.

From what I can see in the photo. The INNER lights have 3 wires on this that would confirm this.

Plasticfreak

You are correct!

HeadsU.P.

H-m-m-m-m-m-. Some model / yrs had a courtesy spare tire carrier light also. It was tied in with the rear cargo area light.

DUB

YES...this spare tire carrier light is tied in with the interior courtesy lights so when you open the door it would light up.

I know that 1980-1982's have it but I can not remember if a 1978 and 1979's did also.

Anyway..the light socket is not in the above photo and has an ORANGE and WHITE wire in the socket and takes a 194 bulb.
