Adapter connector for bare-wire transducer/Garmin 12-pin fishfinder

This adapter is designed to connect a Garmin fishfinder equipped with a 12-pin connector to a variety of transducers. It allows integration of existing or custom transducers, whether they have bare wires or 12-, 8-, or 6-pin connectors.

This adapter is specifically designed for Garmin fishfinders with a 12-pin connector.

The adapter is compatible with all Garmin fishfinders in the CV and GT series with 12-pin connectors.

Yes, this adapter is compatible with all Garmin GT-series 8-pin transducers.

Yes, the adapter supports many Airmar transducer models with bare wires and 8-pin connectors. Compatible models include the Airmar B41, B60, B75, P19, P66, P79, SS60, TM150, B117, B150, B164, SS164, B175, B258, B260, and M260.

When choosing the mounting location, ensure that:

The adapter cable can easily reach the transducer connector on the fishfinder.The device must not be submerged in water.It must be mounted at least 15.25 cm (6 inches) away from an electrical interference source, such as a motor.If the mounting surface is not suitable for screws, you can secure the device to a structure using cable ties (not included).

For installing the adapter, you will need the following tools:

A drill with a 3.2 mm (1/8 in) bitA Phillips screwdriver size #2A 3 mm flathead screwdriverCable ties (optional)A wire cutterA wire stripperA 21 mm (13/16 in) wrenchAn adjustable or 15 mm wrench (optional)

To prepare the transducer:

If the transducer has a connector (12-pin orange, 8-pin blue, or 6-pin black), cut the cable as close as possible to the connector. Pass the cut end of the cable through the nut on the side of the housing and pull it through to the other side. Use wire strippers to remove approximately 90 mm (3 1/2 in) of the outer jacket and foil shielding. Use wire strippers to remove approximately 6 mm (1/4 in) of insulation from each internal wire. It is recommended to tin the exposed wires.

No, paddlewheel speed sensors are not supported on the 12-pin fishfinder connector via this adapter. For transducers requiring this function, an alternative solution may be necessary.

Use a 3 mm flathead screwdriver to connect the transducer wires to the 12-pin wiring block of the adapter. Each wire must be connected to the corresponding function according to the wiring diagram (e.g., Shield/Ground to pin 1, Temp + to pin 2, etc.).

For Airmar transducers without temperature capability or a separate temperature sensor (such as the P79), you must install a jumper between terminals 1 (Shield/Ground) and 2 (Temp +) on the adapter wiring block.

Yes, it is recommended to tin the bare wires of the transducer before connecting them to the adapter’s wiring block to ensure a more reliable connection.

Once the wire connections are secured, use a 21 mm (13/16 in) wrench to tighten the nut around the transducer cable. Then, place the cover on the adapter and secure it with the four captive Phillips screws.

Yes, this adapter is compatible with Garmin DualBeam 77/200 kHz transducers (Garmin GT 8-pin transducers).

Yes, this adapter is compatible with Garmin Dual Frequency 50/200 kHz transducers (Garmin GT 8-pin transducers).

Yes, the adapter's connection block includes dedicated pins for Garmin Transducer Identification (GID) and Airmar Transducer Identification (XID), allowing the fishfinder to automatically recognize the connected transducer.

The adapter housing must be mounted at least 15.25 cm (6 inches) away from an electrical interference source, such as an engine, to ensure optimal operation and avoid disruptions.

Using this 12-pin adapter with an Airmar P66 transducer will enable the fishfinder and water temperature functions, but will prevent the speed paddlewheel from working correctly. If speed data is required, use an 8-pin sounder port with the 010-11613-00 adapter.

The adapter housing must be secured to the mounting surface using screws. After drilling pilot holes of 3.2 mm (1/8 in) and inserting the screws without fully tightening them, place the housing onto the screws and slide it into position. Once the wires are connected (with the housing unmounted), tighten the screws until the housing is firmly secured.
