If you know what vehicle (year/make/model) the trans came from, go to Rockauto and look for the connector. I've had pretty good luck, that way.
The description usually gives the part number(s). If you don't want to buy from them, you can probably find it on Amazon or at your local parts house.
This is what Rockauto coughs up for a 90 Cadillac Deville, just for example. (Obviously not exactly what you're looking for, but you get the idea.)
