1957 Chevrolet Truck Suspsension Upgrade - Easy Air Ride, Part 2
One Step Closer to Superb Handling, Great Performance, and an Aggressive Stance
September 30, 2011
Even though the ECU and its connections are weather/waterproof I still decided to mount the unit behind the driver’s seat on the lower rear cab wall. The OEM fuel line opening in the floor pan made a perfect route out of the cab for a majority of the wiring.

With the ECU located and mounted, the next thing I did was to locate and attach the display/controller harness and the display/controller unit itself. The latest RidePRO e3 represents a leap forward in onboard suspension controls, starting with a completely new control panel that is sleeker and brighter than its predecessor. The auto-dimming display is easily visible in the sun and is only 3⁄8-inch thick. One thing I really like about the controller is that the interface buttons are backlit and have a distinct click to let ya feel when a change has been made. Another cool bonus is the unit’s two mini USB connections, which allow a variety of panel mounting and connection options—though I’ve still not decided whether I’ll mount it on the dash or leave it on the seat next to me.

Scary huh? This is what it looked like under the cab after threading the three main harnesses down through the opening in the cab floor. Because of space limitations I dismounted the valve block to make connecting the harnesses to the solenoids easier—the weather-tight connections are OEM-quality, making external mounting worry-free.

After wrestling with the rat’s nest I’d created under the cab I re-bundled the individual harnesses and began running each toward their appropriate locations. The grey and red two-wire harness is the power/ground source for the compressor so I of course routed it rearward to the compressor and made the connection.

Back inside the cab, once the ECU is mounted there’s not much in the way of inside wiring. One of the three small wiring harness sections located inside the cab is the USB cable for the controller, next the harness for the dash-mounted ride-control button, and finally the three-wire (two red, one yellow) main power harness you see here. As my tag denotes, the yellow wire goes to a switched positive ignition connection and the pair of red wires to direct battery positive—piece of cake.

Another trip under the truck had me dismounting one side of the air storage tank so I could rotate it down and install the pressure switch into the threaded bung on the topside of the tank. In both the foreground and background you can see the 90-degree air line fittings. One is air in from the compressor and one out to the air supply side of the solenoid block. It’s important to note that thread sealer must be used on each threaded connection to ensure against slow air leaks.

While I was under there I snapped a quick image of the ground connections on the left framerail. As is the case with any electrical wiring a good ground or grounds is of utmost importance for proper function.

The balance of the ECU connections is straightforward. The ride height sensors attach to the unit with weather-tight threaded connections and the ECU is clearly labeled for each corner of the system.

The third and final interior wiring assembly is the button and controller for the ride control. This aforementioned button is the one that controls the ride configuration allowing you to switch from a soft ride for everyday driving to a stiffer performance setting for more aggressive driving/handling.

With the various harnesses routed, secured, and connected the final chore was to route, cut, and connect the air lines. RideTech includes this neat little tubing cutter that ensures perfect cuts every time, doing so without crushing the semi-rigid air line. The air lines are simple to install too—all you need to do is push the air line firmly into the air line fittings until they bottom out and then give ’em a bit of a tug to seat ’em firmly in place.

Here you can see both the electrical and air connections for the rear Shockwaves. All are routed carefully and tied together in a bundle that’ll stay in place and eliminate any chafing as the truck is raised, lowered, and driven.

As I ran the air lines (and the wiring as well) I made sure to use grommets and in a couple of cases some rubber fuel line (as you see here) whenever and wherever I ran line or wiring through openings in the truck body and/or frame. At this point all that’s left are the final power connections. Those will have to wait until I wire the complete vehicle and decide on its battery location. When I do (and that should be shortly) I’ll show those final connections and give you a better idea of the RideTech components used as well as their specifications, features, and retail pricing. Stay tuned and we’ll finish up soon.
