Export Gear/Flaps Indicator

I have successfully exported the DDI's, RWR, and EFEI to my 2 small monitors following advice found here, but NOT the landing gear and flaps indicator. I do not use Helios or touch screens. Placed these lines in MonitorSetup but no joy:

GEAR_INTERFACE=
{
x = 3135;
y = 820;
width = 300;
height = 500;
}

Help please. Do I need a device_init.lua? or other file mod?

I think only digital outputs such as RWR/MFD etc' can be exported like this, not analog dials and switches...
