The original wiring is set up for incandescent bulbs. When you add LED lighting you need to be sure the lights themselves are configured correctly. This means you need a "3 wire" tail light. One wire for brake, one wire for tail and one wire for ground. You also need a "3 wire" headlamp (HI + LO + ground).
Yellow (AC power) goes directly to the "tail" wire. Yellow (AC power) goes to the brake light switch and out to the "brake" wire. Yellow/green is ground (connected to the black wire that is your engine/frame ground).
There is no "increase of power". There only one power source directed to different functions. Based on the diagram that was posted, you need:
Yellow to violet (for tail).
Yellow to brake light switch to white (for brake)
Black to yellow/green (ground).
(first colour = chassis wiring, second colour = tail/brake light wiring)
