can anyone tell me how I could install a switch that would allow me to turn off these two lights at will or where I could find a wiring diagram for a 2004 4wd tundra?

 

Daytime running lamps, there is a gray 2 Pin connector on the inside fender (up top) on the driver's side, pull the connector out, no more daytime running lamps

If you ever need to have them back, re-attach connector.

As far as the cargo light, I didn't care very much to re-wire, but I remember reading something about a mod to keep them on, I don't know about turning them off completely like a switch. I imagine it's built into the relay somehow.

 

thanks I saw that but it looked too easy. If you see deer on the side of the road or in the road in front of you they get blinded and if you just turn off the headlights just for a few seconds the can see to get out of the way. Thanks again
