No the actual headlight wire in the engine bay is what I tapped for power.
I don't think automatic headlights with the auto dimming gauges is possible. It has to do with the way in which the gauges need to see voltage. In order to change color they need to see the white light voltage first then the blue light voltage. If that happens then the lights will change color. However, if the white voltage and the blue voltage arrive at the gauge at the same time the gauge will default to the primary color (white). With the way our automatic headlights work they are powered upon accessory. What that means is that if its dark enough outside they send voltage to the gauge at the same time as the white light voltage so that the gauges default to white. In theory, you could add a time delay relay on the
headlight voltage but due to the way the "smart" charging system works in our car the headlights do not get constant 12 VDC. When the voltage drops it signals to the relay to shut of and the gauges will go white then when the voltage goes back up it triggers them to change color again so it ends up turning into a rave driving down the highway.
