With the three remaining wires from the ECU connected to ground, a constant 12-volt feed, and the third to the ignition, providing power only when the key is switched on, the system was powered up and the tank charged. There are many options accessible using the menu, but the basics are: top left two buttons control inflation and deflation of the front left ShockWave, the lower two doing the same for the rear, and those on the right similarly controlling the right side. The three buttons across the bottom are for three preset suspension heights, usually deflated, ride height, and inflated. These can be set by following the simple instructions, at which point the "Setup Required" display will go out. I elected to wait until the car is more complete for this, as I'll doubtless have to remove some of the airlines or wiring during the remainder of the build for paint, etc.
