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: https://www.hi-1000ec.com/product-list/15 They come without pins, so you'd also need a set of those: https://www.hi-1000ec.com/product-li...&Submit=Search 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 https://www.tehnomagazin.com/Auto-ra...-Connector.htm (The more detailed descriptions in the right-hand column are from the info for a Y-adaptor that I bought off eBay): Connector A: 1. GND Chassis ground (-12V) 2. DIM NC 3. BATT 12 Volt battery/constant (+12V) 4. P.A. Power antenna 5. FL- Left front negative 6. FL+ Left front positive 7. GND NC 8. ACC 12 volt ignition switched (12V+) 9. BATT NC 10. RHEO- NC 11. RHEO+ Dash light illumination 12. TEL NC 13. FR- Right front negative 14. FR+ Right front positive Connector B: 1. FL+ 2. FL- 3. RL+ 4. RL- 5. FR+ 6. FR- 7. 8. 9. RR+ 10. RR- Hope that's some help. Phil |
