Rotax 912S - additional inputs, again

[bsorbye]

I would like to have Flap and Trim indicator inputs, and at the same time use the two standard resistive CHT senders that come with the engine.
However, I have only a single fuel tank! Can the second fuel tank gauge input be used for Trim, and have the value displayed as Trim indicator?

Unfortunately not.
