Okay I'm getting a slow battery drain since installing my vintage "Sony Minidisc Receiver mdx c7900" into an 04 xterra. I takes weeks to drain the battery to the point where the vehicle wont turn over. I removed the receiver until I can identify the drain on the battery (95% sure its the receiver). I'm sure of all my speaker connections, its just the other power and misc connections (in the photos) I'm not sure about.
Can any problems be seen from the attached images?
Would leaving the faceplate on drain the battery?
Any electrical issues related to that model receiver?
If anyone needs better pictures or labels, let me know.
