Update - it was a real pita to replace. Had to take the rear tail rack (Alt Rider), luggage rack (Happy Trails), under rear seat cover, and tail light assembly apart. I also had to take the gas tank rear mounting bracket off to get to the plastic cover over the ABS system for access to the wiring harness. I did not pull the plastic wiring cover off of the new rubber plug to load it up with silicone to stress relieve the wires. Instead, I put 2 layers of shrink wrap on the plug assembly. I think that made it much stiffer, which should help. I replaced the stock bulb with an LED unit. So maybe I won't have to take it apart again. After 40000 miles, it was sure dusty and dirty under all of the miscellaneous piece parts....
