I am installing a used Becker AR3201 transceiver for a friend. It didn't come with a harness. I can make the harness myself and could use a standard DB-15 connector. However, I would prefer to use the latching type connector that Becker specifies and you can see on the AR4201 and AR6201 (which use a DB-25 instead of the needed DB-15). Does anyone know of a source for the DB-15 latching connector? Thanks, John
