Need help reverting to factory radio and...
 

I am trying to revert to the factory stereo setup on my 99 Disco 1. The previous owners were [at least] thoughtful enough to use a wiring harness for their aftermarket stereo so all the original plugs were intact.

I have removed the aftermarket radio and installed the original radio along with the code to unlock it but other than a little muffled sound out of the rear-door subs I have nothing from the rest of the speakers.

I've taken a few pics and attaching here for clarification. There's also a couple pics of things I am curious about.

Thanks for any help you might be able to provide.
