Parasitic battery drain

I have a 2015 Fiesta with a parasitic battery drain issue. I've narrowed it down to two circuits, F23-RH Ext Light and F28-Directional Indicator fuses in the Battery Junction Box. Both circuits are drawing approximately 2 ma based on voltage drop reading across the fuse of 0.01 VDC converted to 2.0284 mAmps according to Fuse Voltage Drop Table for Mini Fuses. This is also verified with amp test on the battery (hooking up multimeter in series with negative battery cable). According to the wiring diagram both fuses go the the BCM. F23 goes to the Gray connector and F28 goes to the Blue connector of the BCM. I can't find a wire diagram of the BCM. If I isolate either circuit, separately or together, by disconnecting the cable connector to the RH Head Lt Assembly or the Turn Signal Assembly on the steering column the fuses still draw amps. I was able to find a same model BCM online, but made no difference when I swapped it out.

So at this time I am out of ideas on how to proceed. Any help is much appreciated.

Thanks in advance.
