This, of course, is subject to the rules.
It occurs to me that you could use the NO side of the micro switch to drive your LED to the ground of the Jaguar. You'd want to grab your source voltage from some safe 5V supply, possibly on the Jag itself. Though this only tells you the position of your limit switch, not necessarily what the Jag is reading.

Reading the actual pin on the Jag would be trickier, as you'd need to make very certain you're no accidentally pulling the input high or low with your circuit.
