[Milsurplus] Connector for RCA AVR 20A

Wed Jul 8 07:38:55 EDT 2015

Can anyone provide information on the correct original connectors for the receiver to power supply on the AVR 20A. The manual specifies the cordage as MI 19518 but does not provide the connector information. The receiver has a short pigtail that then connected to a longer line to the power supply. This is for a Stinson L-5E aircraft installation. 
Thanks
