The amp turn on wire that you read about is for when adding another amp.
Just replacing the factory stereo with an after market, you should be able to wire the adapter up to your new radio - then when you pull the old stuff out, the new should just plug in.

The brand adapter you have is (left blank intentionally!)
Most success is with the Metra or Axxess (I think you'd want GMOS-04 but research to be sure).
Try that.



But it looks like from this pic the speaker wires aren't connected
(those speaker wire aren't used if there's rca's to the adapter)

Yes, the Metra GMOS-04 is the correct harness for a BOSE replacement.

Scosche has been reported to be problematic.

I'd say run longer RCAs into a standard home amplifier and see if you get sound. If so, then you may have something wired incorrectly between the head unit and the amp (some had turn-on wires, but I don't think that early of a model year did). If all of your wiring is correct, then I would recommend trying a different harness (yours may be defective).

If you don't get sound from the home audio amp, then you have a head unit problem.

well you need to find the broken part, first. then replace it.

I'm going on the assumption that you connected all the wires, properly, and that it worked with the factory head unit.
correct.

i just dont know the area thats broken. im going to go off what i think is wrong is with the amp not getting power. i havent ran the subs yet, so i wont be able to confirm its the amp unless i can get bass. but i took some pics of the plugs on the factory amp and i have a dc plug right next to it so im going to splice power over to the amp and see what happens. and then ill go from there.

ill be back in a second with some pics. i cannot confirm on what the power wire is yet.

the metra gmos-04 is the correct harness for a bose replacement.
