XPUICP help needed

I need to monitor the dataref "thranda/cockpit/actuators/FuelSwL" in my Carenado Navajo for x-plane 11.
It has 3 states: 
"thranda/cockpit/actuators/FuelSwL=0" - or
"thranda/cockpit/actuators/FuelSwL=1" - or
"thranda/cockpit/actuators/FuelSwL=2"
This is for the fuel actuator handles. When they are moved with the mouse, the dataref changes to one of
the 3 states; 0 = inboard, 1 = off and 2 = outboard.
Since I can't find the offsets, I've assigned my own to them. 0x66C1, 0x66C2 and 0x66C3 and mapped them to 
switches through spad.next. This all works as it should. The handle moves and the dataref changes.
Now I need to monitor the different states in Mobiflight to help with the logic for annunciator lights.
I've tried entering the Datarefs and Offsets in XPUICPOffset.cfg but can't seem to get it right. I've
looked at the examples and tried those that were close in what I needed to be done,but can't seem to make 
it work.

This is one of many combinations I've tried.

Dataref  LTankHandleIn    thranda/cockpit/actuators/FuelSwL    int
Offset    0x66C1    UINT8    4    rw    $LTankHandleIn >LTankHandelIn @

I know that the right one is out there...somewhere!
Any help would be appreciated.

Thanks,
Steve
