How do you turn off the headlights while the engine is running especially if you are in the parking lot waiting?
In the older model Tundras, the running lights are the
headlights, not the parking lights. If you open the hood, and look
right behind the left headlight, there should be a grey wire with a
bulky connector. It should be located right between the battery and
the side wall of the truck. Simply disconnect the grey wire and the
running lights should come on. You could buy a new daytime running
light relay that just loops the circuit back to itself, but this
works just the same.
