Question
Hi, i have a 1999 mazda protege, and the cd player does not work. i have since bought a cheaper model deck to install. my question is, can you give me step by step directions? ive already got the current stereo pulled out, but not disconnected.
i know thats a hefty question, but id like to do it myself tonight, as im leaving on a road trip tomorrow morning. any help would be appreciated!

Answer
Here is the wiring chart for the 1999 Protoge:

You must learn the wiring chart for your radio and match the functionality.  
You can google for the owners or install manual for your radio model (you did not give it in the question so I can't help you with that).

Using a wiring harness makes it easier to install; and especially to remove the radio after installed, if you have to in the future.

Here is the wiring from above for your help.
