Looks like i'm late with comments. But just for information.
Connector marked green is stock connector for tow hitch socket. It has 5 pins of 6 which are turns, tale, stop and rear. (and no rear fog).
Blue is junction connections and as far as i understand is responsible for signals on upper rear lights. My European left hand drive wiring has empty wires of turn signals in upper lights and empty fog and rear in right lamp.
For European Prado left lamp is a dummy.
I mounted left-side rear driving light. Drilled
25mm hole and installed the used factory bulb.
The stock wires are missed between brown socket near the lower frond left door hinge and black socket behind the glove box.
Rear fog has red-yellow wire, and rear driving light has red-black.
Two pieces of wires half-meter long can revive empty wires in rear upper right lamp.
But i have no idea about turn signals and consider that the blue junction connector in the screw-jack place is responsible for worknig turns. Hope that this information will help.
