The metra wire harness adapter has the orange wire with white stripe labeled illumination which is the same as my head unit. However there is no pin in the illumination spot on the factory harness that the metra adapter plugs into. So to get the radios dimmer to work do I need a 12v circuit with headlights on or a variable voltage circuit(cars dimmer knob for dash lights) with headlights on?
