Holley Tach Input Ignition Adapters

Not Yet Reviewed

Holley tach input ignition adapters are only used on applications using a CD box, such as an MSD 6AL, while not using timing control. They plug into the connector labeled "ignition" on the main harness. The loose yellow/black lead connects to the "Tach Out" terminal of the ignition box. Never connect this wire directly to the ignition coil.
