    I need help identifying the holes under the doors of my 2021 Tundra. Each hole has a rubber cap. These are not the 6 threaded holes used for mounting running boards. These are just holes that run along the bottom edge under both front and back doors.

    Welcome from NY.

    Pictures would help for clarification.

    Pretty sure they use these holes to pump in some waxy anti-rust fluid.

    Don't think you would be mounting running boards directly to your door. Maybe they're drain holes?

    Here are two images of the plugs. If they are drain holes, I wonder why the plugs were not removed by the dealer.
