Yeah, the reading lights are map lights. They got that name way back when paper maps were common, and the navigator read the map but wanted to keep the light away from the driver.
Do the map lights turn on and off like they should? So far it sounds like an issue with the white wire that grounds the lights. One item that might help would be to unplug the interior light control module, it is mounted up next to the OBD port under the dash. It controls most of the interior lights and unplugging it might isolate the fault. If unplugging it turns the lights off then it is faulty, if it makes no change the issue is the white wire, probably a grounded splice point behind the headliner.
Where you outlined could be the area, but all of the lights ground through the same splice so if both of those lights are on, the others should be as well. That is why it's difficult, they have multiple lights connected to the same points.
