I have searched my car (95 940T Wagon) and determined that there is no pre-existing wiring going to the back of the wagon for a CD changer. So, I am going to try to do it myself. Other than promises that it won't be too hard, can anyone point me to a book with pictures, or a website that would show how to do this. I am sure that if I remove the correct pieces of trim at the bottom of the doors, and under the dash, it will be an easy job, but I don't want to start guessing about what should come off and find a lot of stuff to put back that I never really should not have removed in the first place. Thanks for any suggestions.
