Couple of Questions
 

Hi,
I currently own an 1987 Audi 5000S 2.3L Automatic. I have a couple of questions. The first is, is there any wireing harness kits for a stereo system for my style of car. The reason is that, I want to know if I would have to make a custom wireing harness for a stereo or if there is any out there I can buy. I want to put in a cd player instead of having the factory Tape player in it. The second question is that what would I have to do to hook a laptop into the car to do some changes into the programming of the car. So that I can do some performance mods later on in the future and get everything running correctly to the mods. TIA
