LED strips draw so little power it wouldent matter if they stayed on all night, however the power going back to the bed is timed to turn off automatically after a certain time anyways. I once hooked a 12' long strip of #5630 LEDs to a 9v battery to how long it would take to kill the battery. It took over a week of continuous running to do that. Your fears are unfounded.
I connected my additional LED strips at the front of the bed to the LED's wiring in the bed (Lariat). Now they all come on and off automatically (or when I push the button, and then they automatically shut off).
I'd cut it out. The strip I ordered did not come with a switch. I just popped out the existing (Lux package) switch and wired it to it. So when the truck turns the bed lighting on...or I do it manually, all comes on.
I left the switch attached; two reasons; 1) didn't want to mess around with cutting and splicing and 2) in case I needed a backup switch. Small enough to hide in the space.
I like the idea of the lights coming on automatically and purchased a motion detector switch for the purpose, but balked at the install when I realized I would only need the lights at night. I suppose a motion and light detector switch would work. Hasn't been a 911 mod so I haven't devoted much time to it.
