offset Start Valve open PMDG

[Geferson Alves]

'm using a Boeing 737 FlitePal engine start switch, which is made with a solenoid. I've configured the GRD, OFF, CONT, and FLT switch positions using PMDG Event IDs. However, for the solenoid's ARM function, I need an output (annunciator). I tested this with X-Plane 11 using the Zibo mod and utilized the "Start Valve Open" DataRef, which was easy to identify with DataRef Editor. It worked correctly, disarming the solenoid at the right time,
 specifically when the "Start Valve Open" annunciator extinguished on the EICAS. My current challenge is finding this same "Start Valve Open" information within PMDG (for their 737) or FSUIPC. 
I'm looking for an equivalent offset or variable that I can use as an output to control the solenoid's arming.

Take a look at the offset mapping document for the PMDG 737 (Offset Mapping for PMDG 737NGX and 737NGXu.pdf) - note that you need to enable data broadcasts in the PMDG to have these offset populated.  There is this offset (1-byte each, for each engine):

BYTE x 2

ENG_StartValve[2]

true: valve open

or maybe this one:

The current position of this switch is also held in offset 0x64FC:
