An air suspension control system, primarily for use with a vehicle, which increases ride stability and minimizes air losses to the air suspension control system during normal operation of the vehicle by utilization of an air restriction valve to restrict the air introduced into or exhausted from an air spring in response to a received control signal. According to the invention, the generator is connected with the tuner and the audio demodulator is connected with the generator. Electrical power may be provided via power cables attached to seating assemblies of the electrical contacts. The printhead bracket may also be made of statically dissipative material and grounded to the PCBA.
