I'm pretty sure its not plugged into anything from the factory, so might be for a feature not included on the 4runner, but vehicles that use a similar wiring harness. I've got the same thing on mine, never plugged into anything when I go it, and it was all stock

Our Canadian friends get a windshield washer fluid level warning light feature. The plug is for that.
