Just need a push in the right direction.....

It's all part of the rear body harness. There is a connector behind the driver side kick panel. The harness runs along the drivers rocker panel, down back by the driverside rear seat and enters a trunk. The dome light connector should be just inside the trunk behind the rear seat on the drivers side. I'd start by disconnecting the connector behind the kick panel and reinstalling a fuse. If it doesn't pop then take the fuse out, plug the connector back in and disconnect the dome light. Then reinsert the fuse. If it doesn't blow then the short is located in the tail light harness beyond the dome light connector.
Here's is the main rear harness in the background.

And the dome light connector behind the seat

Disconnected the rear harness and the fuse still popped. Disconnected the column connection and the fuse didn't blow. Have the wires hanging down for access to them and the fuse didn't blow when I plugged the connector back in. After pushing the connector up where it should be out of the way saw a spark and the fuse blew again. It could just be a cracked insulation on one of those wires cause I moved the connector and saw a spark and so far found at least one wire with a small crack in the insulation.
