Just have my prusa i3 working... but I have got my x and y all messed up

Hey,
So finally managed to get my printer working well and printing like a trooper.

However I have just printed out a phone case and realised the holes for audio connections are reversed. Looking some more and I think I have my X and Y wired up wrong.

So if I just swap the connections on the board is the printer going to forgive me for this silly mistake or am I going to run into more issues/problems? I see someone else mention one axis printing the wrong way but changing the coding and endstop fixed this.

I have my endstops in the right place (going by a picture of the thing, at the back with the Y axis motor and near the left with all the electronics and motor for the X bit.

And yes I know I am an idiot...

For anyone stumbling on this post. I just swapped the cables. Then tested to ensure that the end stop worked as expected (manually held the endstop button down tried to move in the negative direction). I am glad I tested this as I also needed to re-wire the end stops! Which is obvious when you think about it.

All still working well!
