Vehicle Info NeededTach Adapter for Non-Current Limiting Ignition Systems
Ships Tomorrow
Lowest Price GuaranteeWhen a 6 or 7 Series ignition is triggered through its white wire or points terminal, many voltage-triggered tachometers and fuel injection systems will not read correctly off the ignition tach output. This adapter conditions that signal so the gauge or ECU sees what it expects, which is the usual fix for a tach that reads erratically or not at all after an ignition upgrade.
MSD 8910 Tach Adapter Features:
- Corrects operation of most voltage-triggered tachometers and fuel injection systems.
- For ignitions originally equipped with a ballast resistor, described as non-current limiting.
- Used with 6 and 7 Series ignitions triggered by the white wire or points terminal.
- Covers a wide range of Chrysler and Dodge applications from 1987 to 2003.
 | Tach/Fuel Adapter, Points and Amplifier (Factory Ignition Module) If you are triggering an MSD Blaster, 5,6, or 7 Series Ignition with its white wire or points terminal, you will need this Tach Adapter. This unit 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. |
 | Magnetic Pickup If you are using the magnetic pickup input (green and violet wires) to trigger your MSD Ignition, you will need the #121-8920 Tach Adapter. This 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). |
