Installing LEDs in Bed of Tacoma

So im going to install LED strip lighting in the bed of my truck because i have a tonneau cover, so you cant see anything in there at night. Now im going to install the switch near the side compartments. So my question is for you guys is where should i tap into to power the lights. Anything close in under the bed ?

Thanks guys for help..

All help/opinions welcome .

I tied my LED bed lights into the trailer harness at the rear bumper. It's only powered when the ignition is on so there's no chance of leaving the lights on with the cover closed. I mounted a rocker switch just inside the left rear of the bed.

Here are a couple of pics of my install.

 

I ran a wire from the battery so I wouldn't have to have the key in the ign.

Pics should be in my build

 

Nobody's doing a refrigerator-style switch that turns the light on and off with the tailgate?
