LED Door Catch Plate Install Problem

I recently installed 4 of these LED catch plates behind my door release levers, but I am having difficulty locating the +12 volt source for the front passenger door. I was successful wiring the rear doors to the "Tail +" wires which illuminate when the headlights are on, the driver side door was wired to 12 volt accessory but the front passenger door has only three 12 volt constant feeds. Unfortunately, the service manual connectors and wiring diagrams for the front doors are wrong and with my meter I can't locate a suitable tap. Has anyone been successful at installing these LED catch plates on the Santa Fe?
