I need help with Arduino and a ULN2003 driver board

[crob09]

Hi everyone,
I am trying to connect a driver board I have to an Adruino.
In a nutshell, I need to know what pin "step, dir, min, max" are on the driver board. The driver is labeled "in1, in2, in3, in4" for the I/O's on the controller, and labled "A, B, C, D" for the motor connection.
Below is the I/O configuration to connect the stepper drivers to the Arduino, it is for a 3D printer project.

Digital I/O #0 = RX
Digital I/O #1 TX
Digital I/O #2 X step (Is this in1 on the driver?)
Digital I/O #3 X dir (Is this in2 on the driver?)
Digital I/O #4 X min (Is this in3 on the driver?)
Digital I/O #5 fan
Digital I/O #6 heater
Digital I/O #7 Y dir (Is this in2 on your product?)
Digital I/O #8 Y min (Is this in3 on your product?)
Digital I/O #9 X max (Is this in4 on your product?)
Digital I/O #10 Y step (Is this in1 on your product?)
Digital I/O #11 extruder motor pwm
Digital I/O #12 extruder motor dir
Digital I/O #13 Y max (Is this in3 on your product?)
Analogue I/O #0 (D14) thermistor
Analogue I/O #1 (D15) valve pwm
Analogue I/O #2 (D16) valve dir/Z max
Analogue I/O #3 (D17) Z min (Is this in3 on your product?)
Analogue I/O #4 (D18) Z dir (Is this in2 on your product?)
Analogue I/O #5 (D19) Z step (Is this in1 on your product?)

I hope someone can lend me a hand, and thanks for your time.

I forgot to add a picture of the Driver board, sorry....
