 Transducer Installation 
Oil Temperature Sensor 
The oil temperature sensor needs to be installed 
according to the directions of the engine 
manufacturer. Dynon Avionics sells oil 
temperature sensors with both 5/8-18 UNF 
(Dynon P/N 100409-001) and 1/8-27 NPT 
(Dynon P/N 100409-000) threads. Ensure that you have the 
right sensor for your engine. Using a crush washer (not 
provided) between the sensor and the engine case, tighten the 
sensor according to your engine manufacturer’s 
recommendations.

Route the wire from pin 7 on the 37-pin 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 w

First, mount the fuel pressure se
using an Adel clamp or other secure method. The fuel 
pressure sensor must not be installed directly to the 
engine due to potential vibration problems. Next, 
connect the fuel sensor to the engine using approp
hoses and fittings. Its pressure port has a 1/8-27 NPT pi
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 fo
emergency landing.
