Apple Modem 300/1200 Serial Cable Pinout

I’ve got one of those Macintosh 128K/Apple II/Lisa Apple Modem 1200s, but one thing that my modem didn’t come with was the DE-9 to DE-9 cable for the Macintosh 128K. I‘ve searched around but can’t seem to figure out the pinout to connect them together. Does anyone here have a cable that they can pull the pinout from?

2 NO CONNECTION 2
3 - 3
4 NO CONNECTION 4
5 - 9
6 - 6
7 - 7
8 - 8
9 - 5
