||view mirror, consider this. In the Z32 roof, the finisher that includes the reading lights and their switches conceals a fan assembly. (I’m not sure all option packages include this fan as it might be related to a thermostat for automatically regulating heating and cooling settings.) The fan is only powered when the ignition switch is on. To power a V1, I tapped into the hot wire to this fan and used a screw in the ceiling metal for a ground wire anchor. Your camera hot and ground wire can stay concealed in the roof until they exit the notch in the plastic finisher that conceals the rear view mirror mounting screws. When I'm not using the V1, I simply remove it and tuck its 2 conductor wire out of sight between the PS sun visor and roof.
