I went into my radio to install a Bluetooth adapter. I just wanted to look. I did not do any of the install but when I went to put radio back it did not power on.
There is a red wire that you see in the foreground of the picture that is sitting out. It looks like it was yanked from somewhere.
It you plug the red wire into the bundle of yellow wires the system powers on. However, that bundle is the battery I believe. The issue is that the system will not turn off when car is turned off.
I'm pretty sure the red wire is the problem but I just don't know how.
Here is the picture
Just to clarify. The red wire that's exposed is getting power. I hooked a multi meter up to it.
