Not sure how helpful this'll be, but a while back I was looking into this with a view to making up an adapter so I could troubleshoot a CR-905 on the bench. (This is the radio from a 1994 940 Wentworth saloon).
I had great difficulty finding the connectors, but eventually found that they're Yazaki items, and I was able to get some from Japan (this was before the recent changes in import duty on small value packages, so might be more expensive now). I bought them through Rakuten Global Market, but the link I have for there seems to be dead now. These are the family of connectors though:

They come without pins, so you'd also need a set of those:

And they also need a retainer for the pins and that seems to be sold out.
Connections on the printed circuit board are labelled as below, and agree with the pinout for the CR-905 at
