Down Stream Oxygen Senser Orientation.

Down Stream Oxygen Senser Orientation.
I got another catalytic converter for my 2003 E-250 with 5.4 liter engine. I don't remember how the 02 senser was oriented. The flange on the converter has three holes so depending on how it is turned the sensor port can be at 12 o'clock, 8 o'clock or 4 o'clock. Can anyone tell me how it should be oriented?
