                If, after installing an MSD Ignition Control, your ta�chometer, fuel pump relay or electronic fuel injection (in foreign vehicles) doesnt operate correctly, your ap�plication may require a Tach Adapter. This is due to the trigger signal not being strong enough to trigger both the MSD and the factorys components.There are a few Tach Adapters available and for more information see pages 152 and 153. Each Adapter is simple to wire in and will have your MSD and vehicle firing away in no time! If you are triggering an MSD Blaster, 5, 6, SCI, or 7 Series Ignition with its white wire or points terminal, you will need the PN 8910 Tach Adapter. The PN 8910 will correct the operation of most voltage-triggered tachometers or fuel injection systems that do not work directly off the tach output terminal of the MSD Ignition Unit.

                    Ever wonder how you can install an aftermarket tachometer on a vehicle with no distribu�tor and multiple coil packs? MSD has the answer with the Distributorless Tach Driver! The compact Tach Driver measures only 1.5  x 3.5  x 2  and is potted with a polyurethane compound for vibration and water protection so it can easily be mounted under the hood. It wires inline on the coils 12 volt supply wire where it senses the current going through this wire and converts this information into a 12 volt output signal that most aftermarket tachometers use as a trigger signal. It can be used on 4, 6 or 8-cylinder engines.

        With only two touches you can quickly and accurately program your speedometer.   Classic Instruments SN74 installs in-line between the transmission pulse signal or ECM speed output and your electronic speedometer.  The SN74 converts all known pulse signals, including pulse sendors that replace mechanical speedo cables on early transmissions, factory VSS (vehicle speed sensor), and the computer (ECM) output signals to 16,000 ppm or 8,000 ppm signals.  It also includes an additional 8,000 ppm output signal for your cruise control.  Real-time calibration feature allows total fine tuning.  The filtered power source eliminates interference.  This compact module works with most all aftermarket electronic speedometers and the module can be mounted anywhere inside your vehicle.
