Well, found where the trunk light was supposed to be... I thought it was odd
that there was no light. When I took the plastic trim off, that reveals
the mechanism and access to the center brake; I saw a dangling harness.
then looked at the plastic cover, saw the rectangular hole... The light
assembly is missing.

So, I had a COB style LED panel, TWO in fact from a set of fogs I removed
them from. Attached one to the center brake, and made a trunk light
out of the other one. Gonna look for some OE plugs, see if I can clean
it up a bit...

 

I made my own trunk light

Took these COB LED Panels out of a set of oval fog lamps:


Stuck it to the back of the trunk interior lid trim with DynaMat:




Powers up and works good:




I removed the factory harness and used 2-pin JST connectors.
