Anyone know the correct way to wire the two frogs to micro switches in a 3-way? I keep getting a short. I've gapped according to the Fast Track template and I've checked to make sure the tie gaps are cut clean as well.

Using a SPDT contact based on throw rod position for each of the two rods, the picture below shows the wiring set up.

The farthest (left most) frog is controlled by the short (center) points.
The complex dual frog (center) is controlled by the long (right most) points.

I estimate I have about 5 pounds of coupler springs somewhere in the vicinity of my workbench.

Thanks for the diagram. I was doing it correctly but had reversed a wire at the first micro switch. Now everything's fine.
