LED board and status

I have a status LED board I want to connect to my APM 2.6, and I hoped it would reflect the red/blue LED blinking. But when I connect to A10/A11, I just get constant light.

Is there anything I need to change in the code to make them work as expected ? Is there a place in source where I enable/disable features like this ? I do have some programming skills, and have compiled and uploaded locally built firmware.
