Audio Systems: car cdtuner wiring, pioneer yellow, pioneer deh

Question
Dear Cody M

I recently bought a used car cdtuner,  a PIONEER DEH-P545R, unfortunately I could not find the instalation manual could you please explain to me some of the wirings.  I am installing it into a volkswagen polo.
the following wirings are at the back of the cdtuner.
   Black with a kind of fuse holder at the end of it
   Blue with(system remote control)sticker onthe wire
   Yellow (Battery )   
   Red
   Yellow ( ILL)
   White  (Door Swith)
   Black
I guess the yellow is connected to the 12v dc,  the red would be connected to the accessories and the last back wire is the ground.  Could you please explain to me what
- the first black wire,  
- the blue which has a system remote control sticker
- the Yellow with ILL sticker and at last
- the white with the door switch sticker and where shall I connect them all the above.  The speaker wires are easier so I should not have a problem.

Thanks in advance.

with regard

Answer
Samson ,

 ok first you should use a wire harness adapter kit this is about 8-10 bucks from radio shack and it will wire matching color for color to your pioneers harness then simply plug into your factory harness plug so you have no guess work .. now if your factory plug is missing you have to do a straight wire in which this site www.streetdreams.com/wires can help you with your color codes for your car .. now the harness on the pioneer yellow is 12 volt constant which needs a direct connection to the battery / red is 12 volt ignition or accessory , blue is usually not used along with the ILL , now the 2 ground i have never seen so for those i cant help you .. if you want a sure fire diagram call or email pioneer they have tons of information they will give you to help you out .. hope this helps you out if you need anything else let me know

thanks
