Ok so I put a cd player in my car and sometimes it stays on even with the keys out of the car. After it did this I changed out the radio but the same thing happend. This is a 88 dx that had the factory tape deck in it when I gotthe car. I used adapter plug I had left over from my 91 lx (worked fine when it was in that car) all conections are soldered and heatshrinked. I have checked all my conections and they look good. Any thoughts on what could have gone wrong?
