Insulated Block Setup for More Complicated DZ-1000 Non-Derail Wiring

I had a situation as depicted below. I wanted both SW 1 and SW 2 to align straight when a train approached on the straightaway from the right (C1 and C2 insulated sections), but I also wanted SW 1 to point straight and SW 2 to point turn when a train approached from right of the turnoff (B1 and B2 insulated sections). Insulated section A to SW1, B2 to SW2, C1 to SW1, and C2 to SW2 all follow the steps as outlined in the DZ1000 instructions. The B1 to SW1 connection  required a reversing of the green and yellow connections. But note how the two insulated sections B1/B2 and C1/C2 are separated by an insulated section in between. This was necessary to prevent a rail truck's wheels from straddling across two insulated sections, leading to chattering and both red and green LEDs lighting up on the DZ swicth machine push button controller.
