CPU 2 Repair Help

I fell into a 93 RX-7 that has been sitting for a long time, the previous owner connected the battery backwards doing untold damage.

I have going through the electronics and repairing them. My current project is CPU 2 in the fuse box.

The electrolytic cap on the PCB had popped and caused damage to a small part of the board. After reverse engineering the PCB I decided its easily repairable but there is one particular component that was completely off the board and the silk screen was removed as well. It is the highlighted resistor in the schematic image. I assume it is a resistor that finishes the voltage divider network as measured by P101. But I could only guess what the value is.

Does anyone here know, or have a picture I can use to figure it out?
