samsung r519 netbook

hi guys. does anybody know where the black and grey wires connect to on the motherboard. i had to take it apart as drink had been spilled on it, but thankfully i removed the battery and power supply, and it still worked. but i cant remember where the grey and black wires connect to.
any help would be appreciated

if you watch the video below, at about 2 minutes 58 seconds it shows a black an grey wire, hope this helps.
