Hey went to gamestop found out how to do this if your second wiimote wont sync without screwing something up
keep wiimote align with sensor bar best as possible (just cause okay?)
simply press each button on the wii and wiimote once (dont hold) (i pressed controller one first but im sure it dosent matter)
LEAVE CONTROLLER ALONE DO NOT TOUCH AT ALL
after that it should sync! solved my problem! hope it solves yours!
