Borden Resistor Identification and removal for 3 phase Direct Reference

Hello ,
I want to add two more VTs for 3 phase system and I know I need to remove two resistors from the internal circuit board in order to add the additional VTs and get an adapter.But I am confused which one is the Borden resistor,where exactly it resides in the schematic.can anyone identify in the schematic??

Here’s a pic of an IoTaWatt PCB with two burden resistors removed on inputs 13 and 14, circled in red. The blue circles are burden resistors still in place on inputs 1, 2, 3, 11 and 12. This is an older board with 24 Ohm burden resistors (240 printed on top). Newer models have 20 ohm.
