cargraphic Porsche 718 4.0L exhaust controller

cargraphic Porsche 718 4.0L exhaust controller installation. A walkthrough of me installing this controller on my own car. This controller enables the exhaust valves to be run in 3 modes, mode 1 standard Porsche operation of the sports exhaust button and eco valve control, mode 2 valves open, mode 3 valves closed. In std mode the eco closes the valves between 2000 and 4000 revs, to reduce noise levels. With the valves held open, the music is available at all revs, not just the very top end.
