If the bulbs are 2 filament, then ground will be the frame.
Otherwise the black is usually ground.
on the zuki, ground is black with a white stripe everywhere.
a black wire would have power to it at some point.
turn the power on and hit the turn signal, the intermittent signal will be the brighter filament.
the dimmer of the 2 will be the running light.
