    I want add a led light to the bottom of the front pass door to light up running board when the door is open. My wife had a stroke and its hard for her to see foot position. Could I tap into the puddle lights? Is possible what wires should I look for. I have a 2011 xlt. But title says xlt/king ranch

    I don't have a wiring diagram for your vehicle, but my earlier 2000 uses only a 7.5 amp fuse for mirrors. You need to figure out how many amps the lights your installing draw. These vehicles don't like tapping into existing circuits to install add ons. If it were me, I'd probably tap into a 15 amp or higher circuit. Do the lights come with any kind of switch? Probably not.

    You should get the factory wiring diagram for your year before adding anything.

    There are two circuits that you could tap into but you need to know the amount of current draw in them first. The circuits to look at are Fuse 9 (interior lighting) and Fuse 10 (puddle lamps) in the smart junction box - behind right kick panel. Both are rated at 15 amp but have an inline FET controlling them.
    If you add in an LED light assembly as a parallel circuit, if the LEDs amount of resistance is the lowest in the circuit it will cause an increase in current draw and may overload it. It is safer to see how close the load is to the fuse rating.

    Goggles some other websites and found something called "dome light supervision wire" is this a wire I can tap onto?

    Wouldn't this cause the LED lights to turn on with any door when opened or just simply turning the dome lights on can cause the LED lights to turn on? I think following you steps is an idle source of power but OP should tap into the door ajar to the front passanger door as the switch that way only opening that specific door turns on the lights.

    The lights would be on the inside door panel,so turning the dome light on wouldn't matter.
