Heated Pitot and Skyview + VP-X

[High_Flyer]

Hi.

I'm new here. I am Alain, living and building an RV-7 in France.
The airframe is 80% done and I will soon install avionics and engine.
I'll have a Dynon Skyview system, Dynon VHF, intercom, AHDARS, EMS and the heated pitot.
And a VP-X Sport.

Question:
The pitot heater controller has 3 wires:
Red for power, connected to the VP-X
Black to ground
White to??

The Dynon installation guide says:
white (wire) : connected to a light bulb (or resistor and LED) tied to switched ship's power. This line is grounded when the heater controller is powered off or not fuctionning. (...)

I couldn't find anything in the VP-X manual.

I don't think a light is necessary in my setup as I'm pretty sure either the Skyview or the VP-X can give me warning of the pitot being off or not fuctionning.

How do I connect this white wire from the pitot heater controller???

Thank you.

Alain.

I have the pitot indicator wire (white wire) going to an EMS input. The EMS display is configured so that when pitot heat is off the "pitot heat" indicator is green. When pitot heat is on the indicator is red.

See "EMS Sensor Definition, Mapping and Settings" starting on page 7-61 of the install manual.

Thank you for that.
I have to admit I haven't read the EMS section yet as I thought is only for engine sensors.
I'll have to read further and think about it...
