I am installing a RAC trim servo (elevator) and I was wondering what I will need to do with the 3 wires from the servo (position) when I complete the install.

Is there a wiring diagram of the harness that comes with the EMS that can show me this?

I cannot yet afford the EMS but I will be installing a Dynon suite of EMS D120 and EFIS D100 - by the way, can the trim position only be shown on the EMS? I have several "extra" inputs I want to wire into them, and I am worried the (three?) the EMS system caters for may not be enough if I need to use 3 wires from the servo.

Thanks!

Check out the full D120 manual on the documentation of our site for more complete details, but here's the nut of it:

"If you are using the output from a Ray Allen servo or sensor, connect its white/orange wire to the Dynon 5V excitation line (pin 18), its white/blue wire to ground, and its white/green wire to your GP input of choice."

There are 3 GP (general purpose) inputs on the D120 to choose from.
