Be careful, the right angle connector is backwards.
I'm pretty sure pin 1 is marked on the board.
If you used a straight connector instead of the right angle one then the notch should point to the edge of the board.
Pin 1 is next to the keyboard connector and the edge of the board.
The ribbon cable counts in order from 1 to 26.
The IDC connector counts in a zig zag.

When in doubt, measure it.
For example, run this:
' Change line 10 each time you run this
10 P = 11
' make each pin a digital output and set each pin low
20 for n = 1 to 20: setpin n,8: pin(n) = 0: next n
' set the selected pin High. It will be the only one (except the 3.3V and 5V lines) that is high.
30 Pin(P) = 1
Then get a multimeter and check the DC voltage between the pin you think is 11 and Ground
Change line 10 to P = 12, and repeat.
