GM Tach Sender Kit

Most GM engines with the EST ignition system have 2 plugs going into the ignition coil, the gray connector typically has a purple wire and a gray wire, the purple is your power "feed" wire & the gray is an analog tach signal wire. SOME engines beginning around 2004+ have eliminated the gray tach feed, this is needed for driving either a Perfect Pass or analog tachometer.

This plug is used if your coil is missing the tach wire & you need this for a replacement analog tach signal.

Used when installing a TRD Conversion kit into a boat with a bad MMDC controller and no analog tach signal is present.

Kit includes 24' gray marine wire, and coil plug, and wire connectors.
