SV-EMS-220/221 Installation and Configuration
7-44 SkyView System Installation Guide - Revision S
Route the wire from a general purpose input pin on the EMS 37-pin Main Sensor Harness to
where the oil temperature sensor is mounted. When routing the wires, make sure that they are
secured, so they will not shift position due to vibration. Strip ¼” of insulation off the end of the
wire. Crimp a #10 ring terminal onto the end of the wire, ensuring that a good connection is
made between the wire and the connector. Unscrew the nut from the stud on the oil
temperature sensor. Slip the ring terminal onto the stud and secure the nut over it.
Some oil temperature sensors that SkyView supports (but are not sold by Dynon), such as the
GRT FT-LC-01, have two wires. To connect this style of sensor, connect one wire to a Ground pin
on the SV-EMS-220/221 – any of Pins 3, 13, 16, 17, or 30. Sharing of an SV-EMS-220 Ground pin
/ wire is acceptable. Connect the other wire to the chosen general purpose input.
Rotax 914
Rotax supplies the oil temp sensor – P/N 801-10-1.
Fuel Pressure Sensor
The fuel pressure sensor may be connected to any general purpose input pin on the SV-EMS-
220/221’s D37, however, we recommend it be connected to pin 8 on this connector.

101715-000)
Mount the fuel pressure sensor securely using an Adel clamp or other method such as using a
transducer mounting block on the firewall. Dynon does not recommend mounting the sensor
directly to the engine to minimize the chance of mechanical failure of the transducer due to
engine vibration. Unlike Dynon’s older fuel pressure sensor, the Kavlico pressure sensor has a
dedicated ground wire, eliminating the need to use the sensor case as ground.
The fuel pressure sensor port has a 1/8-27 NPT pipe thread fitting; you may need adapters to
connect to the pressure port on your engine. Locate the correct fuel pressure port for your
engine. This port must have a pressure fitting with a restrictor hole in it. This restrictor hole
ensures that, in the event of a sensor failure, fuel leakage rate is minimized, allowing time for
an emergency landing.
Connect the red wire to SV-EMS-220/221 D37 pin 18 (white/red). This connection may be
shared with other sensors, depending on your installation.
Connect the green wire to SV-EMS-220/221 D37 general purpose input of your choosing
(nominally pin 8)
Connect the black wire to Ground. Any the black ground wires on the SV-EMS-220/221 D37
harness are suitable for this purpose.
Legacy Dynon Fuel Pressure Sensors (100411-000 and 100411-001)
Dynon Avionics no longer supplies these sensors except for plug-compatible replacement. For
new installations, Dynon Avionics recommends the Kavlico pressure sensors (above).
First, mount the fuel pressure sensor to a fixed location using an Adel clamp or other secure
method such as using a transducer mounting block on the firewall. The fuel pressure sensor
