We found this wire inside this hole in the trunk and my son says “I think it attaches to that wire here” and… so it does.
But what does it do?
Anyone?
That wire is for your trunk light. \You should be able to find the light bulb socket near the edge of the trunk lid.
Oh! Wow! Had her for 2 years and never knew we had a trunk light.
Thanks!
Does it work?
Yep trunk light. I added one to mine, it’s nice to have.
Put in one of the LED lights and it turns night into day! Use one of the reverse lights that only have one pin.
Can someone confirm where it connects to on the loom where it exits the trunk or does it run a separate wire to somewhere?
On Mustangs (not enough experience by myself on Cougar tails to remember offhand), a green/yellow wire is run either integral to the harness or taped to the outside of the harness. It connects to the underdash harness (obviously) up front, and exits the tail-light harness about where the rear courtesy lights on the driver’s side exits with a female bullet. A separate wire runs from there up to the trunk, where it meets the wire coming from the lamp assembly itself.
Yeah. It was mid day when we connected it. So we couldn’t see it light up until I saw the reply and actually LOOKED for it.
But it’s working.
I guess the previous owner didn’t want it on and tucked the wire inside.
Or the switch in the light does not work and the light stays on all the time resulting in a run down battery.

Randy brings up a very good point. Check that Scott. It may not be going out. Mine turns off with the trunk lid about 1/2 way down maybe. At any rate make sure it goes off. I can’t imagine why anyone would unhook it unless they snagged the wire some how continuously putting stuff in and out of the trunk, or perhaps were at sometime having a battery drainage problem and thought that light was the culprit.
Yikes! Good point!
I checked it out…and the light stopped working.
Weird.
We’ll look into it this weekend.
Since the wire runs through the webbing on the underside of the trunk lid it is also possible that the wire has rubbed on an edge and now has a bare spot causing it to short out.

On mine the wire broke off at the light itself. Took a little bit of creativity to repair it to get it working again since that part really doesn’t come apart at all but I was able to save it
There is a mercury switch in the lamps. Usually they work or don’t. The glass tube the mercury gets broken from rough handing during the bulb installation. With that said, the hood and trunk lamps are now reproduced. You could buy a replacement and steal the mercury switch from a new one if it fails to go off or is broken.
Thanks all!
