Default Poly-Planar MRD60 AUX input wiring

I purchased a boat with a Poly-Planar MRD60 sterio. It was one of the originals and does not have an AUX input. Poly-Planar no longer makes the IMR-4 interface that plugs into the MRD60 ribbon connector to provide 2 AUX input connections.

I understand that the ribbon connector can be wired for an AUX input if you have the wiring diagram. Does anyone have a wiring diagram for the connector - or an old IMR-4 interface?

I contacted Poly-Planar in MD and they claim that that model has been out of production for so long they no longer have a wiring diagram for it (or they didn't want to look....)

Any Ideas?
