Hello. New to the 3D Printing thing and I've assembled a FT Kossel kit

Hello. New to the 3D Printing thing and I’ve assembled a FT Kossel kit and replacing the RAMPs with the Replicape and repurposed BBB. I’ve re-assembled the stepper motor cables to be in alignment with the image on the wiki.

I’m having more difficulty determining the wire placement for the end-stops. The cables were wired straight through for the RAMPs but the image indicates the middle and an outer wire swap places. How do tell which wire goes where?

bah! Scroll down and RTFM some more and there’s the answer. never mind.
