My battery was dying every day, and I figured out my radio was staying on even when I’d turn the car off and when the keys came out. I asked many people on forums and they said unless my radio was direct wired, it shouldn’t do that. So I started with the solenoid because it seemed like an easier replacement. That failed to fix it but hey new parts. So I got under the dash and removed the switch as well as a light bulb for the ignition. Hope i described things well enough to help someone doing the same thing I did. Maybe you won’t struggle like me 😂
