It's time to install my Greddy Profec B Spec II but I realized I dont have one of the connectors it came with..

Would anyone happen to know where I can get another one of the connectors? Radio Shack? I could probably contact Greddy but I envision waiting a month for this little piece.. Even the name of the connector or something would put me in the right direction.. I can take a pic of the Greddy Unit to show what the female side looks like..
