I have a 2004 tundra double car (the first design based off of the sequoia) with the factory set fog light wiring harness. I was going to get a set of lights and install them but realized i have no idea how or when they'd turn on, since the models that have the fog lights already installed have a control setting on the turn signal lever. as far as i can tell the models that don't already have them have a different lever without the ring to turn the fog lights on or off. If i install a set of lights would they turn on automatically with the low beams? and if not can i/would i have to install a separate relay and switch for them?
