With the mechanical side of the install complete, it was time for wiring. RideTech makes this simple in the extreme, as there are separate harnesses for the valve block, display/controller, height sensors, and pressure sensor. Even if you didn't follow the instructions (which RideTech put in a big envelope with "do not open" printed across it!) you'd have a hard time messing this up! I welded a length of 6x1/8-inch steel plate across the rear seat supports, on which I mounted the ECU, first determining that the various harnesses would reach their destinations from here. I was going to mount it behind the lefthand taillight, but the controller wire wouldn't have reached the front seat, though I've since found out RideTech offer a longer one!
