Field Fix Harness 1986-1989 GN/TTA
This simple "Plug-And-Play" harness is designed to assure un-interrupted charging system function. It provided backup current to the field of the alternator in case the engine's own system fails, assuring a fully charged battery under otherwise "tow-truck" conditions. A MUST HAVE add-in for your turbo Buick or TTA! Plugs into wastegate connector and alternator.
