Another cabinet lighting question

bcbud3

I will be putting some LEDS under cabinet lighting. The walls will be open. I will most likely mount a switched plug above the cabinets (will be hidden from view). I plan on running 3 wiring whips to the 3 sections of cabinets where the lights will be. Above the cabinet i will splice the whips to the transformer and then plug it into the receptacle. Couple of questions:

For puck lights that are pressed into holes cut in the cabinet bases, what is done to hide the wiring in the cabinet?

If i put in strip lights, how do you hide the wiring?

Pics of installs would be great! Thanks
