Ok, this is gonna sound really stupid but I need a little help here installing some indiglo gauges. Got everything out and on and all fine but I am pretty unsure of the wiring and don't want to mess anything up. What do the directions "headlight power supply" refer to? What is the easiest way to get to this and what should I be looking for? What is I were to just run the inverter's wire to the lead of the clearance light, would that work too?

Please help.
