As long as the correct coil pairs are matched, the only difference it'll make is what direction the motor runs.

Okay, I've spent 2 minutes on the Makerbase website and given up - have you got instructions for the board, and in particular which are the A+/A- and B+/B- terminals on those 4 way plugs?
If so - it's easy - work out the coil pairs on the stepper? If you have an Ohm meter (DMM etc) then measure which pair of leads has ~1-3 Ohms resistance between them - of the four wires, there are two pairs each with that low resistance. Then you need to wire ANY pair to the corresponding A+/A- pins (doesn't matter which way around). Wire the OTHER pair to the B+/B- pins - again, doesn't matter which way around. There's a 50/50 chance that the motor will spin in the wrong direction - then swap the pins on ONE pair only (so swap A+/A-, for example).
If you don't have a meter... buy one. Or short two wires on the motor together (with nothing else connected, of course!) - if you find two that makes it more difficult to rotate the motor by hand - you've found a pair. Confirm by shorting the other pair with a similar increase in resistance to rotation.
If it makes you feel better - you're not going to burn the house down. The one thing you must do, however, is avoid removing the stepper wiring when power is applied - it's a good way to destroy the drivers (read up on collapsing EM fields)

Its the red an black wire that always throws me, I keep thinking its live/earth but of course its just polls. It worked wired as in the diagram.
Thanks

I pinned one of them up with single puponts in case it it didn't work but worked fine first time
