Apparatus for a wireless tachometer receiver. The wireless tachometer receiver includes a receiver and a signal conditioner that drives a conventional tachometer. Conventional tachometers require an input consisting of pulses at the operating voltage of the vehicle, which is typically 12 Vdc. Conventional receivers have an alternating current output that is substantially less than the operating voltage of the vehicle, which is insufficient to trigger the tachometer reliably. The signal conditioner converts the receiver output to a signal that allows for reliable operation of the conventional tachometer. In one embodiment, the signal conditioner is an amplifier that has a gain to drive the amplifier output between zero and the operating voltage of the vehicle. In another embodiment, the signal conditioner is a step-up transformer that has a ratio sufficient to produce an output at the operating voltage of the vehicle.
