I have a z and wanted to install a head unit i bought in 04 and the stock speakers and head unit are horrible.

Which part do i need to buy to connect the unit to the car?

I'm installing an Alpine CDA9855

And does anyone know where I can get pictures on how to take apart my console?

thanks in advance..

 

Might want to check out crutchfield.com. They tend to have a fairly good database that can be used to locate wiring harness adapters and sometimes they even provide decent installation documents.
