Final update - it ended up being the abs/skid control harness. Part # 89516-60090.
Somewhere within the harness the wire must have been just barely stretched, hence why it visually looked ok, checked out with a multimeter and only sometimes triggered the lights. I changed the wheel speed sensor, then the lights stayed on permanently which leads me to believe that some of the pulling I had to do to get the sensor disconnected fully broke the wire that was stretched.
Wire harness replaced and no more Christmas lights on the dash
