Actually there are three types of male connectors on the AN/ARC-5 transmitter 
racks.  A 5-pin for the cable to the RE-2 antenna relay unit, a 12-pin for 
the cable to the MD-7 modulator and one or more 7-pin for the transmitters 
themselves.  As the 7-pin is unique to the AN/ARC-5 transmitter racks and the 
others are not, I assumed when I read Chuck's post that it's the one that he was 
referring to.  But I don't have any so didn't reply.
