Install another bellcrank with its lower end attached to the outboard end of one
of the springs. Connect a Ray Allen position sensor to the new bellcrank at
a point that matches the travel requirements.
Or drive the new bellcrank with a Ray Allen servo (with built-in sensor and limit
switches). Replace the existing motor drive gear with an idler gear.

The value of the pot is very non-critical . . . 1 to 10K would
work . . . it's simply a voltage divider that is biased up
with a 5v source from your EFIS system.
You'll want a MULTI turn pot that will accept more
rotation than what results from full-stroke motion
of the cog-belt against the add-on pulley. Here's
a likely candidate . . .

for a 10-turn device to which you can add the pulley
and bracketry to make the installation.
