What do I need to change in Marlin to get them to work?

Thank you in advance...
You should be using RCBugFix and not the RC. RC-7 is just point in time (a number of months ago). RCBugFix has all the improvements since RC-7 was declared.

When you get the endstops connected you can use M119 to see if they are working correctly. You want to see each one trigger and untrigger.
