Interesting product.? I could have used a couple of them!
Other than mechanically linking a couple of turnouts, I suspect that Walthers probably insulated the two turnouts from each other.? This would give the modeler maximum flexibility to wire them however they needed to, to suit their particular railroad.? If this is the case, just wire them up as you would if you had used two turnouts with insulated joiners connecting the diverging routes.
