greenwire on fuel tank near sending unit

[spareparts]

it should be hooked to the engine bolt, and the gar board plug(run a machine screw thru one of the holes for the plug instead of a wood screw, use a nut on the inside of the hull for the green wire to hook to it), and anything else that touches salt should be connected to green. They tell you the ground bonding wire is a separate circuit than the battery ground, but they usually end up connected at some point. If its hooked to the engine , you shouldn't have to hook it to the battery ground
