In this video, I add the headlight height adjust function (tilt) to my 2008 Toyota Tundra. This feature wasn't available until 2010, but since my Morimoto XB headlights (as well as some other less expensive headlights) have the height adjust motors built-in I just needed to add the wire harness and adjust control. The tilt/height controller that comes with the harness is backlit blue so I ordered a used orange/red backlit one from Ebay. Total was about $155 plus tax.
The harness has connectors that plug into OEM headlights with the adjust motors. The Morimotos (as well as some other aftermarket headlights) have the same connectors so you can plug the harness right into the headlights.
I grabbed power for the controller off a nearby OEM switch that comes on with the parking lights.
