Looking for the sigle tach wire under the hood for HEI wire

Stock dash tach.
Its a birds nest of wires under the hood. I have been looking in the books but just need to know which wire under the hood would connect to the single tach wire coming off the HEI dizzy. Thanks, Joe

Joe - The tach wire, as shown in the schematic below, is a Bk/LD wire coming out of C323. And the EVTM says that C323 is a black connector at the ignition module's place on the driver's inner fender, and that it has 4 connections.

This is a take off I took under Big Brother’s hood, when I installed an OEM tach.
Two wires are going to the tach.
