Thanks guys for trying to help. Here is the back of the CD unit which has the main connector and on the bottom there are two small ones. In my case I do not have pins on the small right and I do have pins on the left one but there was not harness connector on it which makes me think that the car was not pre-wired for CD changer. To my looks like the only option I have is to get a CD53 with AUX pins.


The rest of the pictures are from the trunk harness.
