Ok so I will try to explain this as best I can. I bought a 2000 Sportage a couple weeks ago and only one speaker was producing sound. Aftermarket stereo already installed in the car when I bought it. I took the stereo out and found it was wired all kinds of crappy. looked up the wiring diagram for the sportage and it says light green wire for constant +12v but I don't have a light green wire! Also I have a yellow wire and a brown wire and they aren't listed on the wire diagram at all. so I threw both the stereo red and yellow (constand 12v and switched 12v) onto the black w/yellow stripe wire (switched 12v) and the stereo works! Then I was looking into my fuze panel just for giggles, and I found some wrong fuzes in spots and a blown fuze. replaced the wrong and blown fuze and now my cigagette lighter and stereo are on all the time! troubleshot it down to the "memory" fuze. I have no idea why re-seating that fuze caused this issue! I pull it out and the stereo turns off, I push it in and the stereo and cigarette lighter are on with no key in the ignition. I'm pretty damn confused. I can't find any info on this fuze and what it's for, I assumed it was for the ECM memory, and a quick way to reset it, but now I'm starting to wonder if it is for all of the constant voltage?? Any help with these issues would be very helpful. I'd really like to have all my fuzes in and not drain my battery by having full on power to my stereo all the time instead of just "memory" power. Thanks!
