Skid steering with Navio2

Hello
I have trouble setting up skid steering with Navio2 hardware.
I set servo1 function to Throttle left and servo2 to throttle right. Also set mot_pwm_type to brushed with relay.
I disabled all arming checks and armed the vehicle.
Nothing at all in manual mode. Zero pwm output. I trued both qgroundcontrol and mission planner.
I was able to trigger servo5 and servo6 manually in Mission planner, but that’s all.
Also, where to connect reversing relays for Navio2?

Hi! Did you find how to get the BrushedWithRelay mode work? Doesn’t seem to generate PWM at all…
