18. Carburetor Probe Installation (optional)
Use the J1 connector harness 790200 and insert the yellow wire into the connector pin 5 and the red wire into pin
6. All wiring must be type K thermocouple wire. Do not splice ordinary copper wire in any temperature probe
circuits. Locate the access hole (1/4-24 thread) in the carburetor near the butterfly valve. Remove the screw plug
now in that hole and screw the CRB probe into the carburetor throat. No drilling or machining of the carburetor is
necessary.
19. Oil Temperature Probe Installation
The sensor port is a standard 5/8-18 thread for both the Continental and Lycoming engines. Probe PN 400509 is a
complete assembly using type K thermocouple wire (red/yellow). Connect the wire marked oil temperature
observing polarity. Wire length has no effect on the readings. Oil temperature will be displayed as an independent
temperature digital and bar-graph. Check with engine manufactures proper location for oil temperature. Check for
oil leaks before first flight.
20. Oil Pressure Sensor Installation
Use the J3 connector harness 790422 labeled OIL-P
Oil pressure sensor mount using an aluminum clamp MS21919. Mount to firewall.
Mount the pressure sensor to the pressure line using a flexible hose and fittings (not supplied) as depicted in the
drawing below. Use aluminum clamp to mount the pressure sensor to firewall. Do not mount the sensor directly to
the engine
Connect the other end of the hose to the engine manufacturer’s recommended location for engine oil pressure.
21. Fuel Pressure Sensor Installation
Use the J5 connector harness 790723.
Mount the pressure sensor to the pressure line using a flexible hose and fittings (not supplied) as depicted in the
drawing below. Use Aluminum Clamps MS21919WDG25, or WDG14 to mount the pressure sensor to engine
mount structure or firewall. Do not mount the sensor’s directly to the engine. Connect the other end of the hose to
the existing pressure line. Later, you will connect the pressure sensor to the three pressure sensor wires through
the supplied 3-pin connector. Part No. 159935A is for non-turbo engines and PN 159938 had a second port used
to measure the upper deck pressure on turbo charged engines.
