Illumination cable. Most cars have one, but it appears the cobalt doesnt? I cant set my head unit to auto dim like the rest of the inside because I couldnt find the dimming cable. I was looking at the audio pin out thing, and none of those show as a illumination dimmer or anything. I read somewhere that it is part of the GM lan harness, but like I couldnt find any more information, and have no idea what cable to tap if any to fix that. Luckily the JVC unit has a dimmer feature based on time. I set this, so from 8pm-7am its dim, the rest of the time its bright 
.
.The only real problem i have is that when I change the source on my headunit it seems to pop in the speakers. the pop is in the speakers from the stock amp. Like I dont understand what I could have done to cause a pop. Is that a drawback of using the stock amp with the line level outputs from the back of the JVC? also, I did run both the remote for my stock amp and my new aftermarket one off the same remote cable. Thats OK right? It shouldnt cause any issues?
I used an add a fuse to run the power and I saw #15 was unused, and I use a voltage meter to determine if it was switched or not. It was, so I used hte add a fuse from there, and I was good to go.....Its kinda kool how my HU will still work when I take the key out of the ignition just like the old HU did. Only after I open my door will it shut off. I guess I will need to be careful not to run off hte battery alone too much.
I'll agree that there is more potential in the stock speakers than the stock HU will lead you to believe. I'm finding the stock sub to have very defined limits. It seems to be working out for me sofar. But if you like your music bass heavy; it's got to go unless you only listen up to half volume.
I'm glad everything worked out for ya

Mine pops when I put the volume to 0% and sometimes when the HU shuts off.

However if I change the source, it will make the speakers pop. Also, if i put in a CD (MP3) and switch songs, its pops durring every song change. as soon as you hit th forward button it will pop. Kinda gay, but I guess I can live with it. Besides I have an 8 GB thumb drive hooked to my HU anyway, so no need for me to use CD's any more.

I'll second that, I'm not sure what's up. It took me a few months to figure everything out on my own with a little help from the forums. The pinout takes a long while to decode too. But now that we know how it all works in these cars (pre 07 pioneer atleast) I guess it's up to us to man up and get better info out there.

After putting in the new HU, and leaving all stock wiring attached the stock sub sounded about the same for me. so those who want to upgrade just the HU can, as even the stock sub will still work One really noticable thing I picked up on w/ my new setup was that rock music actualyl has bass. Yea, it does, and with the right setup can sound amazing! Im going back through my MP3 collection, as every song is like a new song I never heard before lol.
Thanks preowner for all your help, and everyone else!
