1995 silverado problem help please!
 

hello everybody im new to the forum and love it already but i have a 1995 silverado and the cd player quit working. the stereo and the cd player are seperate so what i decided to do was order a stereo out of a 1999 model where the cd player is integrated into the stereo. the problem is still not fixed the radio continues to work but not the new cd player. could the wires be bad? in not very good with electronics so any help is appreciated. thanks
