Took a look at the wiring schemes of the breakout board to DZ-2500. Also looked at DZ-2500 to DZ-1008. Looks like the DZ-1008 would be spliced in between the Breakout board and the DZ-2500 connecting to the Red Black Green and Yellow wires as per Z-stuff wiring diagram for DZ-1008 to DZ-2500. Not sure why you want to do this unless to wire to block signals maybe, or power routing? The breakout board has connections for non-derailing feature. This is the first I have looked in to this but unless there is a power restriction on the breakout board I would think one board could be wired to control two opposing switches. Placement of the derailing wires for the out position may be a little tricky but since both opposing switches will be thrown in the out position at the same time. It would possibly not be needed at all.
You will have to download PDF's from Lionel and Z-stuff for the wiring diagrams. I haven't figured out how to link them here.
