MSD 8920 Tach/Fuel Adapter Magnetic Pickup Tachometer Signal Adapter

The MSD 8920 Tach/Fuel Adapter is a compact signal adapter designed for use with MSD ignition systems triggered via magnetic pickup input. When the green and violet magnetic pickup wires are used to trigger an MSD ignition control, a dedicated tach adapter is required to properly drive most aftermarket and OEM tachometers.

This adapter corrects the operation of voltage-triggered tachometers that do not function correctly off the tach output terminal of an MSD ignition control. It also supports current-triggered tachometers, which must be wired in series with the ignition switch for proper operation.

Key Features:

• Enables tachometer compatibility when using MSD magnetic pickup (green and violet wire) trigger input
• Corrects signal output for most voltage-triggered tachometers
• Compatible with current-triggered tachometers wired in series with the ignition switch
• Compact, inline adapter design for easy installation
• Legal for use on emissions-controlled vehicles — does not affect vehicle emissions

The MSD 8920 is a straightforward solution for builders and racers running an MSD ignition with a magnetic pickup distributor who need reliable, accurate tachometer operation.
