you find it there...

 
Rep Power: 802

yes you can find it in the service manual through that link. However general rule of thumb is as follows:

red - power
yellow-costant
black- ground

(same goes for all 4 speakers just know which wires are for which speaker)
X colour - power for speaker
X colour with black stripe - negative speaker

blue- antenna

there may be others for the dimmer and other things, but generally thats all you need to know.
