I am currently installing a SkyView HDX System in a Lycoming powered Van's RV-6 using the latest available documentation. This includes the Dec 21 Installation Guide and Revision C of the Typical SkyView HDX Wiring Diagram. I have 3 questions as follows:
1. The Dynon supplied EMS D37 Harness includes a triple twisted connection for the Fuel Flow Sensor. The 3 wires are physically connected to Pin 13 (Yellow) Pulse Out, Pin 14 (Black) Power Ground and Pin 15 (Red) Power In. This configuration contrasts with the information in the Installation Guide and the Wiring Diagram as shown below:
Question 1 - Is the actual D37 Harness incorrectly configured or is the supporting information in error?
2. Sheet 12/15 of the Typical Wiring Diagram shows Pin17 of the EMS D37 Harness as providing Power Ground to 3 separate Sensors. Question 2 - Instead of just using the wire from Pin 17 could I also use the Grounds at Pin 13 and Pin 30 as well?
3. The EMS D37 Harness and the Display D37 Harness both contain wires that will not be used in my installation. Question 3 - Should these wires be removed from the Harness and Connector altogether or can they be cut back to a suitable length and have their cut wires covered by Heat Shrink?
