Tach hook up.

[Zippy]

Replaced OEM ignition system with a 2 wire HEI and remote coil mounted on fire wall. Not sure which wire and where to hook it for rally gauge package tach. Gray wire to neg side of coil??

Hi, I have my rally tach Gauge gray wire hooked up to the negative coil post. Some of the e body years had the gray wire going throw the bulkhead connector and others had that wire going throw a single wire grommet just right of the bulkhead block. Hope this helps you.
