I can tell from your sparse description, but it sounds like you are:

1.  Trying to install a AN/ARC-5 transmitter in a SCR-274-N or ATA rack.

OR

2.  Trying to install a SCR-274-N or ATA transmitter in an AN/ARC-5 rack.

STOP RIGHT THERE!!!

The circle of pin arrangement on the AN/ARC-5 transmitter and rack connectors
is significantly larger than that for the ATA and SCR-274-N.  The wiring to
the pins are grossly different as well.

Different connectors are used throughout the AN/ARC-5 transmitter system,
because the ONLY TWO COMPONENTS in the AN/ARC-5 transmitter system that are
electrically interchaneable with equivalent components in the ATA or SCR-274-N
system are the DYNAMOTOR and the ANTENNA RELAY.  This is pointed out in many
places, such as the article at http://en.wikipedia.org/wiki/AN/ARC-5 .
