v8 audio question

[Paul DAnneo]

Hello All,
 
I have just revived a 2 owner 150k 91 v8q. Blue/ platnum comfort.
Very well maintained, but bad fuel and older owners almost sent it to be flattened..
New fuel pump, filter, injectors and passed CA smog and on the road. Maybe $1000 into it? Back on the slippery slope.
 
To the question. The changer in the trunk isn't working. The remote says e3. No biggy, as all the music is in my ipod. Cd's are in the shed collecting dust. I was wondering if anyone know the wiring of the pin connector connected to the remote? It seems that all the connections to integrate the ipod into the delta should be there. Rather than the cassette adaptor, or a whole new system. 
 
Anyone btdt? 
 
TIA,
Paul
