JABIRU CHT Sensor
Jabiru engines require a 12mm ring-terminal CHT probe for each cylinder. First, slide the compression washer off the
spark plug. Slide the 12mm ring-terminal probe onto the plug. Now, slide the spark plug compression washer back onto
the spark plug. Reinstall the spark plug into the spark plug hole. Please refer to the documentation that came with your
engine for more information.
Propeller RPM Sensor Installation
The RPM sensor should be installed in the non-impulse coupled magneto if possible (Engines with one
electronic ignition should install the sensor in the impulse mag). The correct magneto can be found in the
engine manual. The sensor is screwed into the magnet vent port nearest the magneto-mounting flange
where the magneto attaches to the engine. Replace the existing vent plug with the sensor. The RPM sensor
wires should be connected to the Engine Harness with Fast On Terminals, Butt Connectors or with solder
and heat shrink. If you are using one mag and one electronic ignition you should use the mag sensor for
your RPM input, as long as the mag is turning you will get displayed RPM even with the mag turned off.
The RED sensor is for Slick Mags and the BLUE sensor is for Bendix mags.
CAUTION: Do not route RPM sensor wires with Magneto P leads or electron ignition wiring. Most Magnetos
have two ports on opposite sides, one near the plug wires and one near the drive shaft. The sensor needs to
be mounted in the port closest to the drive shaft.

ELECTRONIC IGNITION
The electronic ignition input is on connector pin 33. You will need to add a wire or using a pin extractor move
the RPM wire from pin 32 to pin 33. This should only be used if you have dual electronic ignitions.

P-Mags
If using P-Mags you need to verify that they are in 12V RPM signal mode with the manufacturer and connect
it to Pin 33 (Electronic RPM Input). If you have one P-Mag and one Mag you can use either the PMAG or the
MAG sensor for your RPM input, DO NOT CONNECT BOTH.
Oil Temperature Sensor Installation
The oil temperature sensor is mounted on the engine.
Your engine manual should show the proper location
for the sensor. The bushing is supplied with a crush
type gasket that can only be used once. The location is
usually near the filter and should be safety wired to the
engine case. Replace the existing vent plug with the
supplied bushing and sensor. The Oil Temperature
Pressure sensor wire should be connected from the
harness to the transducer by crimping a standard #8
ring terminal to the wire.
