My assessment changes slightly regarding the taillight coming on. I went to verify it, and the tail light does not come on, but power is running across it. Basically when you have the black and red hooked to the green/yellow and the green, both filaments are in series. The brake light filament has 1/3rd the resistance of the running light, (so it is much brighter). The taillight filament just acts like a wire.
But on a headlight bulb, where high and low beams are closer in resistance, both filaments will light. I just verified that.
When you hook the Green/yellow to the red wire, and the Black/brown to the Black wire, no filaments will light because they are both hot wires coming in, and neither filament has a ground.
