I just got it... i know its a plug and play system... but whats confusing me is that there are 3 wires on it

BLUE / BLACK - AUX 2 (-) remote output. the wire povides a negative output when radio is in AUX 2 (300 ma. max output use relay when neccessary)

BLUE / RED - AUX 1 (-) remote output. the wire povides a negative output when radio is in AUX 1 (300 ma. max output use relay when neccessary)

YELLOW / BLACK - SWC output.

I'm not sure if they need to be connected and to what? ANyone did this and can shed some light on thing.

I'm doing this as i'm typing this.. please help asap.
