Same side, though you don't want it all the way to the edge. Might take a little experimenting to find the very best placement, but roughly 1/4-1/3 the way from the hot end should be about right.
I personally put mine in the middle and the ambient of my entire tank is about 79-81. However, my room is generally too cold to put it only on the warm side and allow a larger temperature gradient.

Better to have a gradient, even if the room is cooler. 79 is a bit hot for the cool side. Might benefit by moving it slightly off center towards hot side.
