Hi. I just purchased a Pioneer AVIC-Z1 from an individual for a very good price. But it Is a bare unit without wire harnesses or accessories.  I have found most of them now but I can not find the rca cable harness anywhere for plug 1 and 2. Does anybody know of any place I could purchase the RCA harness? This is the manufacturer product number.

Pioneer CDE-8084 

I do have a harness from an Alpine that fits the connector but its pinned wrong. Would anyone know where I could find the right diagram to re-pin the one I have? Thank you very much.
