Wiring the GBT 10 Adapter Directly to the Sensors on the Trim Tabs
You can wire the adapter directly to the Bennett trim tab sensors where the trim tabs are
installed. Wire the GBT 10 adapter to the sensors according to the following table.

**When wiring the GBT 10 adapter directly to the trim tab sensors, the connection order of the
GBT 10 adapter port wires (blue/white) and the GBT 10 adapter starboard wires (yellow/red) to
the two wires on the respective trim tab sensor is not important.
notiCe: After connecting the adapter to the Bennett TPI or to the Bennett trim tab sensors, cover
any exposed wires with heat-shrink tubing.
Connecting the GBT 10 Adapter to a NMEA 2000 Network
After you have connected the GBT 10 adapter to the Bennett TPI or to the Bennett trim tab
sensors, connect it to the existing NMEA 2000 network on your boat. If you do not have a
NMEA 2000 network on your boat, you must build one. For more information on NMEA 2000
and to purchase additional connectors and cables, go to www.garmin.com.

Connecting the GBT 10 Adapter to an
Existing NMEA 2000 Network
To connect the GBT 10 adapter to your existing NMEA 2000 network:
1. Determine where to connect the GBT 10 adapter to your existing NMEA 2000 backbone.
2. Disconnect one side of a NMEA 2000 T-connector from the backbone. To extend the
NMEA 2000 backbone, connect a NMEA 2000 backbone extension cable to the side of the
disconnected T-connector.
3. Add the included T-connector for the GBT 10 adapter to the NMEA 2000 backbone by
connecting it to the side of the disconnected T-connector.
4. Connect the NMEA 2000 connector on the GBT 10 adapter to the T-connector added in
step 3.
