I know that pushing the cabin lights switch 4 times turn off the DRL's but that state do not remain, every time you turn off the truck and back ok again, the DRL's come up and i need to push the magic button 4 times, that happened every time, is there a way to let the DRL's remain off ?

There are some threads and write ups on DRL killers on this site. You can look in the appearance section, and also the article submissions section. Lots to choose from.

ohh, so the 4 button press procedure is just temporary, i want to add some Morimoto V2 LED bulbs, but i do not want to be on all the time , just when i flick the headlights on with the switch

There's no single correct way to disable the DRLs, that's why there are a few write ups from folks who did them differently.

You can also modify your lighting system with the 4 high mod (high and low beams on together when the stalk is pressed forward, just like flash-to-pass) or even 6 high, to include the fog lights if you have them on your truck.

Factory fog lights are controlled by the BCM via momentary button in the headlight switch assembly, so that's a difficult proposition since that would require reprogramming, or a BCM swap, plus the wiring. Aftermarket with your own custom switch would be easier/faster/cheaper. Also, the non fog light bumper doesn't have the factory mounts, so you'd have to make your own, or do a bumper swap.

I just learned something today. I can turn off the DRL with 4 presses of the interior light switch? Mine might be disabled though because, well, Canada.

Yeah Canada that feature is disabled (regulations).
I did the relay at the rear fuse box mod to disable mine.
For some reason I have not bothered disabling them on my Silverado evem though it is a simple fuse pull.

I did the lancematic DRL killer mod three years ago. Still works fine. One thing I would recommend is to use a very small 12v relay, not the big 30a automotive relay commonly used.
You only need to switch a small control signal to the solid state relay in the fusebox.
I think a small transistor would could do the job too. Possibly even the added relay isn't even necessary - the on current for the solid state relay may be low enough that it should be possible to directly connect the indicator led power to the SSR on - maybe with a small current limiting resistor.
