2015 Malibu LS - Map Light housing

My car was stolen a few years ago. I got it back, but the fuse that controls the map lights, and other various illumination within the interior (door lock button lights, steering wheel lights, etc (15A)), keeps blowing.

Additionally, I had someone attempt to fix it by replacing the map light assembly, but he had plugs left over.

My request is twofold: 1. Any ideas on the short, 2.Does anyone have a picture of what plugs into what inside the map light housing?

thanks in advance!
