The rear of Jamie's chair showing the wiseDX Main unit mounted on a bar acroos the back. The green connector is from Jamie's head switches. The red connector is from the Fox environmental control unit (the wiseDX re-routes the headswitches to the Fox under Jamie's control). Just below the red connector is a silver connector - connectiing the Main unit with the Display unit. Below this is the DX connector. Note the use of tie wraps (red) holding the cables safely out of the way.
