AL12-170/B Plane Power alternator

I am in the midst of electrical connections now that the engine is in place, and am attempting to connect my alternator. The connector on the alternator is a round plug unlike the other alternator connectors Plane Power shows in their drawings. Of course, during the long interval between buying the alternator and now, the plug (if I ever had it…) has gone adrift. Does anyone in the brain trust have a part number for this plug? Thanks very much in advance.

Assuming it's a Denso-based design with internal regulator and having a round socket, these ought to work:

Not enough info

Unfortunately, I neglected to provide some necessary info - the plug is 4-wire, not 3-wire. That said, the link you graciously provided led me to a 4-wire plug that I think will work. Thanks!
