Install of Sony HU w/Bose system

[Espresso]

OK, I searched the forums for wire colors & such with no luck(I searched for "radio wire colors" & stereo wire colors"). I have been installing systems for quite a few years but havent touched a MB unit since the early 90's.
I also normally do complete systems not just a HU. I really do not want to replace everything, because I am on a house building budget...so I gotta keep it on the inexpensive side.

I was going to have it installed locally, but I just cannot seem to either make the appt, or they cannot do it. So i'm going to do it myself.
I need this done asap, as the CD changer took a crap on me & I cannot listen to my CD's obviously(nor' can I get the magazine out of the changer..humph).

As for the radio. It is a Sony Xplode CDX-GT805DX. I also have the Bose' system(with the standard FM reception like we have in the states). I am also going to be running my RCA's & such for future upgrades. I have a 8" bass tube I may install but I dont know yet.

ANYWAY,
As I do not even have a manual for this car(Haynes, chilton's ect.) I am completely in the dark at the moment. I do not even know how to get the center cover off. Just it just pull off & have screws that mount the stereo to the dash?
I have read about the VW adapter.
Is there anything else I need before I go shopping? I already have the tools nessessary to do the job. Just not the the stereo accessories.
I dont even know speaker sizes at the moment..LOL

Well, i'm heading down to look at the car & see what I can figure out.
Thank You all for any light you can shed on this.

I have a Sony HU and the Bose system in my car. By using the wiring diagram that Denlasoul posted and a wiring harness that was provided with my HU, I was able to cut the wires and connect them to the correct places... It works great! (an audio shop previously had told me that in order to get a new HU I would have to rip out the entire Bose system :p )

One thing I think I messed up on was the Bose amp (or sub?) connection. The HU wouldn't work at first, but after I connected that it worked fine. (An explanation came with the wiring harness)

Good luck! :)
