I'm looking for a wiring diagram for a 2003 Oldsmobile Bravada with the Bose factory amp. I found this forum only has information for a 2000 Bravada to be the closest match to any of the other years that are available. I'm running into trouble trying to wire an aftermarket radio mainly because the factory radios harness was cut out of the vehicle when I purchased it so I'm basically left with a bunch of wires to figure out. All of the other threads I've read from the web have had no information for the Bose system. For example, every wiring diagram has a yellow wire as the switched 12v+ but my vehicle has no yellow wire in the radio bay. I ended up running a wire from the fuse to the deck for switched 12v+ for the time being because I had been working on this install for almost a month & was getting frustrated. Since I couldn't figure out the wires, I ended up running a new speaker wire to each door speaker & connecting it to the deck just to be able to listen to music. I left the original wiring in place though because I know I'll be going back to fix it correctly once I get everything figured out.
I purchased the Pac RP5-GM11 wiring interface but I could never figure it out. I once got close to getting power but the wires didn't match up correctly. After I wired the harness to the vehicle's wires I ended up getting power to the blue box from a door speaker coming from the harness. I didn't understand how the 12v wires changed from the bay to the interface, it went from being connected as yellow to turning into 12v as a green speaker wire (the wire had a label on that said speaker). It honestly was an accident that I found it.
I'm not experienced in audio installations & wires so this is really eating at me because I can replace the thermostat on my truck, replace the cooling fan & other maintenance things but I can't wire a radio correctly. Also to be noted, after I wired the speakers they sound horrible. I found that one of the speakers doesn't work & I believe the rest are blown, I'm not really sure they just sound distorted after I turn the volume up. I'm not sure if it's due to the factory amp not being connected or if they're just bad speakers.
What I have:
2003 Oldsmobile Bravada with Bose system & factory amp
Factory radio harness cut out the vehicle
Pac RP5-Gm11 wiring interface with swc
What I need:
Information on how to do this install from start to finish if possible.
