Driving alphanumeric display from Raspberry Pi

Looking at https://shop.pimoroni.com/products/quad-alphanumeric-display-0-54-digits-w-i2c-backpack?variant=804921845

Where does the second + connect to? Do both + + connect to 3v3?

I found an Adafruit .py file to drive a clock on 7 segment display, where can I find one to do the same on a 14 segment display?

Thank you.
