The Distributorless Tach Driver makes it possible to install an aftermarket tachometer on a vehicle that has no distributor and runs multiple coil packs. The compact 1.5" x 3.5" x 2" housing is potted in polyurethane for vibration and water protection, so it mounts easily under the hood. It wires inline on the coils' 12-volt supply and converts the current pulses into a clean 12-volt output signal that most aftermarket tachometers use as a trigger.
