interchange of 9 pin PNP switch

[azureblue]

this is getting silly. My back up lights went out on my 2001 v70T5, so I went to the parts yard to get a replacement. I puled one from a same year / model and it was the female type connector, while my car has the male 9 pin (black and blue) connector. Parts cross reference showed that Volvo 60 / 70 2001 - 2004 should swap, but yet another trip to the parts yard, and looking at 6 Volvos in that bracket proved that wrong. So, really now, what other Volvos have the 5 speed PNP Neutral safety switch with male 9 pin connector?

I see two Volvo part numbers 9495007, 94950078 for what looks like the same switch for the same transmission. Which one is for my car, and why two numbers?

I found out that pins 1 and 2 on the 9 pin connector, are for reverse, so now I can test the switch, which was my original purpose. Test before throwing parts at the car..

I also learned that the AW55-50 transmission is used on several cars - Saab, Nissan, Saturn, and yes, the PNP switch is the same for all cars. EXCEPT for the connector - a bit of plastic wire and metal difference and the price of the PNP switch changes from $31.00 (Saab, believe it or not) to $270. Most everybody else's version connects directly to the switch with a standardized connector, but Volvo attaches wires to it and epoxy pots the wires in place. Except for that, it would be simple to build a wiring harness adapter and use any of the direct connect type PNP switches.

And I learned that it is possible to cut off the pins that hold the switch together and clean it, then replace the pins with nut and screws, but I'm not sure I want to get into all of that, since I found a 9 pin Volvo PNP switch for around $75.00. Time is money.

Thanks to all who helped me figure this out
