Ok i am installing a axxes 2 channel line out converter on a 2004 GMC sierra. the wiring diagram i have says that the rear speakers are: LR brn - Yellow +, RR dk blue - Lt blue +. the only wires i can find that match are running to the heater controls, are they the right ones? BTW it has factory Bose

 
yes they are, but i wouldnt try any modification if you arent properly trained and certified. take it to your local audio shop or flea market\swap meet

 
You can also go directly to the rear speakers..... is this an extended cab or a quad cab?

if it is extended you can grab the wires in a harness in the runner on the drivers side...

if it is a quad cab you can go to the b-pillar on each side and grab the wires.
