G4 PowerMac Duel Monitors

Need some information, if you please.

My G4 tower came with two plug-ins to accomodate two monitors. I still have the Apple connection for VGA that came with the Mac, but I need the second option (male). The male end has 30 Pins and 2 tiny pins on either sided of a flat pin on one end, the opposit end is for a VGA plugin.

I don't have a book anymore, and would sure like to know how to descsribe the second option so that I could order a replacment.

The monitor plug-in looks like this one

The G4 Power Mace looks like this one

Help would sure be appreciated.
