Is there any way I can reverse engineer the wiring for this car CD player? Answered

I have a 2001 Nissan Maxima that I intend to customize just a little (well, a lot).  Recently I was at a garage sale and bought a 6 disk CD changer for $1.  I'm hoping this was a worthy investment since I want to install it in my glove compartment and wire it into a custom stereo system.  That's all fine and dandy, but step one is to figure out how to reverse engineer the proprietary control systems.  Eventually I want the air condititioning, stereo, and this 6 disk CD changer to be interfaced to a computer with a big ole touchscreen in the dash. 

I'm going to need to do a few things:
1. Figure out the wiring for the 6 disk CD changer so that I can power it up, control it through the computer, and connect it's audio output to my car's speakers. 
2. Figure out the wiring for the air conditioner so I can control it with the computer.
3. Get a touch screen that fits in the dash (I'll measure it later), that I can use with a computer with (relative) ease. 

These are my goals for right now.  If I can figure this out, I will be ready for the next phase, actually installing the new dash. 

If anyone can recommend any sources to learn more about basic car work, that'd be helpful too.  I'm used to computers.  The lid comes off.  Screws are all easily accessible.  Parts don't weigh more than I do.  I know where everything goes and what everything does inside.  Since a car is so proprietary, and such a new field for me to be working in, ANY resources would be greatly appreciated.  How do I figure out how to take things apart in my car? 

FYI: The disk changer is marked with part number 39115-s3v-a011-m1

Update (18 August 2012): I added some pictures.  The connector I am holding is the only connector that comes out of the box.

Take it to a car stereo shop and they can probably figure out what it is and sell you a harness for it that will fit that plug.

didnt look at how old this was, but im doibg the same thing for the 3rd time, hoping to apply my learning mistakes from the first two. First, choose a tablet with the ability to do all youll need, and connect with the peripgerals you plan to use. OTG host is a must, or like my first buy(galaxy 10.1)it wont output audio and chwrge at the same time. And the second (nextflook fkexx 11.6)was huge, but no dash app short of a dual boot scenario.
The rest can definatly be done with a kittle computer know-how and a lot of google and youtube searches.

Harnesses are a lainand will be a big part of it. Most conpabiea dont like that kibda thing out there...cuts down on replaxement orders. 90% of the time, google the model and "pinout". Or the model and " reverse wiring harness. Those are the big keywords. jyou can also look for replacemebts for salr on ebay or whereever, and look at the photos. maybe a comment on a forum from someone that had it, messege or email them and ask if they still do, and could they spare a minute to send you some snapshots. The wiring colors are pretty standard. Im doing that wifh a friends touchscreen headunit now, using a photograph of a realone, some individual pins, hot glue, and epoxy putty.

the hardest part of switching from electro to mechanical was the terminology,and how things interconnect. Once youve got an idea of what things are actually called, your aearches will be easier.

Funny to continue this conversation after so much time.... thanks for your input it is appreciated! Instead of trying to implement a mutli-CD disk changer, a couple of months ago I got a bluetooth receiver and today I see your comment. Bluetooth is less hands-on interaction with my media but aftermarket head units have clear pinouts and easy audio in/out interfacing. Not to mention while driving I don't have any distraction from the receiver, just push a button to go to the next track or at a stop light I can browse folders or albums on the display.

Hmm.... not well documented, but I'll see what I can figure out. It's perfect to retrofit into my glove compartment.
