   SV-EMS-220/221 Installation and Configuration 
SkyView System Installation Guide - Revision R    7-41 
If you use Teflon tape or other seal, ensure the 
sensor casing still maintains a good connection 
to ground. 
Rotax 912, Rotax 914, and Jabiru Oil Pressure 
If you are installing on a Rotax or Jabiru engine, your engine comes with a pre-installed oil 
pressure sensor. 
Prior to mid-2008, Rotax provided an oil pressure sensor with 2 tabs for electrical connection. If 
you are using this sensor, connect one of the tabs to a general purpose input pin and connect 
the other tab to ground (an SV-EMS-220/221 ground is appropriate). 
In mid-2008, Rotax switched to a new type of oil pressure sensor made by Honeywell (Rotax 
P/N 956413) with an integrated cable. Connect the red wire of the newer sensor to SV-EMS-
220/221 D37 pin 15 (+12 volt Auxiliary), the white wire to SV-EMS-220/221 D37 pin 6, and the 
black wire (if present) to ground. Select the correct sensor type as described in the EMS Sensor 
Definitions, Mapping, and Settings Section.

In late 2012, Rotax further switched to a new oil pressure sensor (Rotax P/N 456180). It is 
functionally identical to the previous Honeywell (Rotax P/N 956413) sensor, and connects in the 
same fashion as it. However, the connector and wiring for the sensor that Rotax includes with 
the engine may require some assembly. See the diagram below for the pinout of the connector. 
Connect the wire connected to sensor pin B of the sensor to SV-EMS-220/221 D37 pin 15 (+12 
volt Auxiliary), the wire connected to sensor pin C to SV-EMS-220/221 D37 pin 6. Sensor pin A 
need not be connected at all. Select the correct sensor type as described in the EMS Sensor 
Definitions, Mapping, and Settings Section.
