'70 dart cigar lighter socket

Ok, my car is missing the cigar lighter. Can't seem to find one in the resto books. Went to local parts stores today to see what available. My question is, right behind my ashtray is 2, 2 wire connectors. Is one of these for the lighter ? All of the lighter sockets i found have one prong, and a stud out back ....is there a plug and play socket around ???
