These instructions for the Mallory #29074 Fuel Injection and Tachometer Adapter have been written/modified by Sam Solace, the CEO of Century Performance Center, to provide a clearer understanding of how this component works and how to install it.

NOTE: Finding the correct adapter configuration for Mallory ignition products can be problematic. If the #29074 adapter does not solve the problem, there are other ways to get the vehicle's tachometer to operate properly.
