I just had a new stereo installed on my 91.5 Congressional Town Car. It has the JBL system with 6" subwoofer if that matters.

I was able to free the locked up cd changer and get my cd's out. I have a blue wiring harness in the trunk still attached to the cd changer's mother board and am wondering if it's still live?

Where does this blue harness lead to? I'd like to disconnect it without the possibility of having an exposed hot wire.
