    Beginning in 2010, some Tundras came with a magic rotary thumb switch on the dash allowing the driver to adjust the headlights up and down. This is especially useful when tow hitch weight changes the rake of the truck, and causes the headlights to point at the sky.

    I set out to determine what it would take to retrofit my 2008, to include this cool new feature. One thing to note is that Toyota tends to prewire their trucks for all the options. If you have a 2010+ (without this feature) check first if you are pre-wired, in which case, you won't need most of the parts in the following list. Look for an unused triangular shaped 3-pin plug near each headlight

    If your truck is not pre-wired (or you have a pre-2010 2nd gen), you'll need to make up your own wiring harnesses using the information in this thread. Also, note, this is not a step-by-step on how to make these harnesses. One could argue (and I do) that if you are not able to read a wiring diagram and perform basic electrical work, then this mod would be best left up to someone with the appropriate skill-set.

    With all that said, here are the parts you will need.

    90980-11016 headlight motor connector x2 (unless pre-wired)
    82998-24400 headlight motor terminals x6 (unless pre-wired)
    90980-11909 switch connector x1 (unless pre-wired)
    82998-12690 switch terminals x5 (unless pre-wired)

    841520C010 switch x1
    811100C070 headlamp assembly (RH) x1
    811500C070 headlamp assembly (LH) x1

    With all of these parts in hand, you'll need to make up a wiring harness that runs from the switch on the dash, out to the headlights, referencing the following diagram. As you can see from the diagram, you need run only 2 wires from the interior out to the headlights. I went through the grommet above the brake pedal.

    Depending on where you mount the control, you can pick up illum. + and - up from the nearest dash switch. Just tie into the appropriate wires on the selected switch referencing the following diagrams.

    Hehe. I've been too busy modding to write them up. I'll try to do better in the future :)
