"UBG-16T"

:::::

There are two pre-wired Extension Cable Harnesses in the installation kit. One end of each harness has a
16-pin Circular Connector and the other end has no connectors. There will be a type K thermocouple exten-
sion cable for each temperature to be measured. The ends of each of the extension cables in the harness has
a piece of yellow heat shrink marked with its channel number. One of these harnesses is to be connected to
the Left engine's temperature probes and/or Functional Modules and the other harness is to be connected to
the Right engine's temperature probes and/or Functional Modules. Refer to UBG-16T Configuration Form to
identify which harness will be used for each engine.

Mark the Circular Connector that will be connected to the Left engine's temperature probes. The first 4 or 6
channels (starting with channel #1) are used to monitor the Left engine's EGT's. Any additional channels
may be used to monitor other functions. There are 8 channels available on each 16-pin Circular Connector.
Any channel used to measure a temperature (CHT, TIT, OAT, etc.) should have a type K thermocouple
extension cable. Any channel used to monitor functions other than temperature (RPM, M.P., Oil Pressure,
Volts, Amps, etc.) will require a Functional Module. Installation of a Functional Module will be covered later
in this manual.

Mark each of the Type K thermocouple extension cables in this harness (on the yellow heat shrink) with the
temperature function for which it will be used (i.e., CHT, EGT, Oil, etc.). An ink pen or marker works well.

Note: If a wire needs to be removed from a connector, you must use an extraction tool. This tool may be
purchased from E.I.

Mark the Circular Connector that will be connected to the Right engine's temperature probes. The first 4 or 6
channels (starting with channel #1) are used to monitor the Right engine's EGT's. Any additional channels
may be used to monitor other functions. There are 8 channels available on each 16-pin Circular Connector.
Any channel used to measure a temperature (CHT, TIT, OAT, etc.) should have a type K thermocouple
extension cable. Any channel used to monitor a function other than temperature (RPM, M.P., Oil Pressure,
Volts, Amps, etc.) will require a Functional Module. Installation of a Functional Module will be covered later
in this manual.

Mark each of the Type K thermocouple extension cables in this harness (on the yellow heat shrink) with the
temperature function for which it will be used (i.e., EGT, CHT, Oil, etc.). An ink pen or marker works well.

Note 1: Any channel will accept any one of E.I.’s probes or Functional Modules.

Note 2: For channels requiring Precision Connectors (OAT, Carb Temp), you will remove the Slip-on
Connectors and install the yellow Precision Connector as described later in this installation procedure.

Note 3: The wire harnesses for a twin-engine aircraft will arrive with the red Slip-on Connectors removed.
The connectors are left off to facilitate installation. Slip-on Connectors are supplied in the accessory kit and
will be installed after the harnesses have been routed out to the engine cells.
