MSD Tach Adapter Magnetic Trigger
If, after installing an MSD Ignition Control, your tachometer, fuel pump relay or electronic fuel injection (in foreign vehicles) doesnt operate correctly, your application 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. Each Adapter is simple to wire in and will have your MSD and vehicle firing away in no time! If you are using the magnetic pick-up input (green and violet wires) to trigger your MSD Ignition, you will need the PN 8920 Tach Adapter. The PN 8920 will correct the operation of most voltage-triggered tachometers that do not work directly off the tach output terminal of the MSD Control. This Adapter should also be used on current-triggered tachs (hooked in series with the ignition switch). There are a few Tach Adapters available and for more information please check the MSD catalog.
- Adapter corrects most tachometers and fuel injection pump relays that do not work directly off of the MSD Ignition's 12 volt square wave tach output terminal.
- Corrects fuel injection pump relays when connecting a tachometer to and MSD ignition control
- Helps correct electronic fuel injection when connecting a tachometer to and MSD ignition control
