The only light blue/black I can find is the main 12V power run to the master control switch panel in the driver's armrest. It should be lt blue/black at the panel, over to the connector, then on the mating connector through the fender, into the vehicle towards the accessory delay relay.
My point is that if it has come off one of the two mating halves of the connector, you should be able to find which pin by looking at the same wire color on the other mating half of the connector.
If worst comes to worst you could just run the wire without bothering with the connector, even if you need to drill separate holes and use grommets to keep the wire from getting cut up by the sharp metal edge of the holes, then solder (and headshrink insulate) to the light blue and black wires on both ends. If you do that, remember to leave some slack for the door opening and closing. I might even put enough slack to form a loop of wire in the hinge area to further decrease how sharply the wire flexes.
