IT ARRIVED!!!!! My gauge is also consistent with the non-halo style from the look of the backside. My power supply has the B and G switch as well as the dimmer. I believe that comes with all gauges, not just the halo style. I remember asking what the optional 6 color inverter was like and they explained that the one that you get comes with the green/blue option. This was before the whole halo thing came up. I'm really tempted to cut work tomorrow and put this in. If I go to work, I'll put the gauge in on Sunday and post pics.
