Board standoffs ?and my drivers arent listed?

And in that video the STEPPER drives are wired to the DB25. That's where they go.

You may or may not need the enable lines wired up but you wont know until you wire up the step and direction lines and power up the drive with the motor connected to see if the stepper motor locks.

All this information is in the install manual, please take some time and read it thoroughly. It also has links to the breakout board you'll need to make wiring it up easier.
