— Toggle a digital I/O port between TTL low (0V) and high (3.3V/5V) in ARC; select board and port, simple on/off control-signal only.

The BlinkM is an I2C device so therefore you connect it to the I2C port.
If you have a V3 EZ-B it will plug directly in to the I2C port if you want to or you can run wires to it if it's away from the board.
If it's a V4 you can connect to any of the three I2C ports.
it works!
