[R-390] Question About the 20 Pin male bulkhead on the IF deck

If the drawing shows the connector from the underside (I can't tell which way it's represented), then it appears the bent pin is Pin 1 which isn't connected.  Again, though, I can't tell if that's Pin 1 or Pin 2.

Thanks,
Barry - N4BUQ
