need help mickey mousing a cd changer

[chmercer]

i have a cd changer that i want to install in my car, but i am missing some of the wires. It is a sony 10 disc changer. I have the commander unit (the little screen thing) but it is cut off and i dont have the plug that goes into the actual cd changer. So i was wondering if anyone knows if i can just buy some kind of cord with a similar plug and solder the screen piece on to it without problems, and if so, what kind of appliance would have a plug like this? it looks like it might be an svideo plug but i am not sure. Also for the power, i have the plug that goes into the cd changer; it has a red wire and a yellow wire with a transformer thing on the yellow one, after this the wires are cut off. i am not sure how i would go about connecting this to my car, can anyone tell me? (the cd changer was not installed by me in the first place so i am not really sure how to do this.) Finally, there is a headphone jack looking plug that is blue, and says output. i have nothing that plugs into this at all, on either side. can anyone who knows about car audio please help me out? i called sony but it would be like 130$ to buy replacment pieces so screw that :P
