Distributorless Tach Driver

Ever wonder how you can install an aftermarket tachometer on a vehicle with no distributor and multiple coil packs? MSD has the answer with the Distributorless Tach Driver!
The Tach Driver wires inline to the coils’ shared 12 volt supply wire. It senses the current through this wire and converts this information into a 12 volt output signal that most aftermarket tachometers and other rpm devices use as a trigger signal.
The compact housing measures only 1.5” x 3.5” x 2” and is potted with a polyurethane compound for vibration and water protection.
