Hi guys

I need to know the wire color codes on the 4th gen bose wiring harness... I did do a search and came up w/ a post made by YellowBrother:

pink or pink / blue - bat (back up)
blue or blue / black - acc
red / yellow - ill cont
red / blue - light sw
green / white - amp on signal
brown - frsp lh (-) amp
yellow - frsp lh (+) amp
nca??? - grd
light green - frsp rh (-) amp
purple - frsp lh (+) amp
red - rrsp lh (+)
green - rrsp lh (-)
nca??? - grd
pink - rrsp rh (+)
blue - rrsp rh (-)
blk / red - ant sig

Before I go ahead and follow this diagram... I just wanted to make sure if it was for the 4th gen because the thread it was posted in was talking about a 3rd gen and a 4th gen... wasn't sure which year it was referring to tho.

The main reason i need this is because I need to make an INPUT for my in-car PC's sound card... so when doing this, I know that the AMPS must be powered in order to hear the music... so all i need to do is splice a wire coming from the battery directly to the wire found in the wiring harness for the amps, and in between put a switch in order to activate/deactivate them whenevre i want to use the in car PC. Is that right?

I was hoping I could utilize the CD-Changer button on the stock HU since i have nothing connected to that but i'm not sure how i could make that happen.

Dang, i just think i should get an FM Modulator... is the sound quality affected alot vs. a direct connection? Thanks guys.
