Sequoia's with DRL's have a gray electrical connector (D1) located between the battery and the inner fender liner. This connector is fastened to the fender liner and has two wires leading to the Daytime Running Lamp Resistor, also fastened to the fender.

Disconnect this one and your daylight running lights are inoperative. If you change your mind simply reconnect and you are back to stock.
