CD Player trouble shooting, No audio problem Options

[mgpmatt]

Hey guys, yesterday I installed a double din screen into my Celica. I followed the how-to post and was able to do it pretty smoothly. I have a 96 GT with a power amp.

The issue I am now having is that when I turn my lights on the audio stops playing. The screen doesn't flicker, dim, turn off, or stop playing. The audio just stops. When I turn the lights off the audio comes back it, never stopping. I'm not even sure where to begin trouble shooting, but I have a feeling I did one of the wires wrong. Any ideas, suggestion, or help?

Thanks,

Matthew

****UPDATE: I FIXED THE ISSUE: THANK YOU NJC YOU WERE PRETTY MUCH RIGHT ON. I"M STILL CURIOUS ABOUT THE OTHER QUESTIONS BELOW THOUGH****

I'm going through wiring again today, but I did have a couple questions. Here is a link to a few quick pictures I took with my phone that might help explain what i'm looking at.

Looking at picture 2. I connected the wiring harness to the stock connection (blue colored) underneath the amp. What happens to the connection to the OEM stereo that came from the amp? Should I just keep it there or can I remove the cable?

In picture 3. Also there was the cable for the antenna (I believe) that goes into the back of the cd player. In the stock player there were two, a large and a smaller one. What is the smaller one?

In picture one is what I connected into the back of the head unit.
