I am going to put in one of these flashers and to put it in you have to remove al the panels on the hatch. I intend to fit connectors on the OEM wires and the flasher. I will extend the wires down inside the panels to the bottom, that way if I ever have to R&R the flasher I will not have to remove all the panels. Also the flasher is stickied to the hatch, if it came loose it might rattle, if I stuck it on the inside of the hatch on the inside of the face with license plate lights, it could not fall any farther and would be on a horizontal face putting little stress on the glue. These sticky pads tend to creep in the heat and slower in the cold.
