This is a much better setup. That was the old Jaos spoiler, which you had to drill a hole in the old 3rd brake, and you'd see the wire running through. This is much cleaner and it's a simple wire tap in the bundle of wires that comes out of the tailgate which is already there. The instructions tell you what wire to tap too

The old unit also had a sketchy metal clamp system for mounting which ended up scratching the roof and marred the paint over time. No issues with this newer design either. Also, the top was extended on this one to cover the old holes if you had the factory metal spoiler.
