Aux Input - 2000 Altima

I have a 2000 Altima with the AM/FM/CD single deck made by Clarion (CY028).

It has a 8-pin din plug on the back which corresponds to an "Aux In" label on the circuit board.

Does anyone know how to wire a plug (which pin does what) so that I can use this Aux in?

I have not seen any mention of this specific model so I do not know if some of the other wiring schematics will work.

Thanks.

Hmmm, I have the same car ... and before I replaced my HU I noticed the same plug. I was told it was for a CD-Changer that comes OEM in the trunk --an option that i did not get originally. Do you have the 6-disc in dash changer, the HU that has a single tape and cd player in it, or their OEM single disc ONLY radio?

Just the OEM single CD
