John C, my 4-way is wired for non-derailing as shown in my bottom photo of the #8 turnouts joining parallel tracks. I did not cut into my 4-Way tracks.
I did drill the correct size wiring holes into the tracks for power wiring and non-derailing control wiring. The non-derailing control wiring at the V tracks is 22 gauge for the short run to the terminal strip (under the table).
The "DZ-1000 Wiring for Automatic Non-Derailing Operation" does show the turnout V tracks cut which is not needed with the long V control rails. Just be sure the two rails in the V are insulated from each other with hot glue or other.
