Suzuki motor to chartplotter N2K network connection institutions

Description: Wiring

Here is a complete install for the NMEA2000 network if you have a Suzuki motor and a fish finder that has NMEA2000 capabilities.

Also you will need to keep your analog tach connected as it will give you your warnings and disconnecting it could void your warranty.

The bulk of this tutorial is on how to make the wire extension and how to get the wires from inside your motor out through your rigging.

Also going forward you are aware you are doing this at your own risk as with any alterations, there is a chance for problems.

This write up is for my 2018 Suzuki DF60AV motor and some older models will require different parts and set up.
So please see the  link below that has complete instructions and everything you need to know regarding motor years capable of running the NMEA2000 network, including troubleshooting.
This is a MUST READ !!
The link will open a Drop Box PDF file that is courtesy of Moonlighter475 from the Suzuki and THT forums.

As of now Suzuki does not have a “plug and play” NMEA2000 kit found with most other engine manufacturers.
Suzuki has done this to make the customer purchase their SMIS Multifunction gauge that is a plug and play, but costs about $500.

In order to use your fish finder, with or without a chartplotter, it must have NMEA2000 capabilities.
If it does have NMEA2000 capabilities, you will need to purchase and connect the following.

Parts List:

- Suzuki SDS Adapter : 990c0-88136

- Suzuki OEM SMIS Engine Interface Cable (V3.5) : 990C0-88149-354

- Garmin N2K starter kit: 010-11442-00

- Lowrance NMEA 2000 starter kit: 000-0124-69

** You can purchase either one of these starter kits.

*** NOTE: You can actually make the SDS adapter cable if you can find the correct connecter for your motor.

To make your own SDS adapter cable, you will need 2 of the following for post 2008 model engines.....
For pre 2008 model engines require a different connector, refer back to the link above....

- 4 Position .090 Sumitomo HM Series Sealed (Waterproof) male Connector (Suzuki Out Boards )
Part #: 4P090WP-HM (need only the male connector with pins)

Also you will need at lease 15 feet or more of 3 wires, Red-Black-White is the standard. These wires and the 2 male connectors above with the pins crimped on the wires and inserted into the connectors will make your SDS wire harness.


Detailed Install instructions and install video:

First locate the the SDS female connector which is typically located on the front side of the motor, under the cowling. It should be protected by a rubber boot.

The next step is making a SDS adapter cable extension.

First you will need to measure the length from your motor plug, through your rigging, to your dash.
Then gather 3 wires with the preferred colors being Red-Black-White.
(Note at the time I did mine, I did not have Red wire so I substituted with yellow.)

*For OEM Suzuki SDS adapter cable: This set of 3 wires will become an extension to the OEM Suzuki SDS adapter cable.

**For diy SDS adapter cable: This set of 3 wires will become your SDS adapter wire harness.

(This is regarding my model motor, different years and horsepower could differ.)
With the cowling off unscrew the 4 bolts on the port side of the bottom cowling and remove just enough of the rubber seal to open the lower cowling a bit.
This will will give you access to the rigging cable boot.
On the left side of the boot there is a hole that you can punch though as this will be your access hole for your SDS adapter cable wire harness.
Tape the tip of your 3 wires together and from the outside of the rigging boot, push the wires through the hole you made to bring the wires to the inside of the lower cowling.
At this time leave the wires there.

What I did next, your choice here on how you want run your wire extension harness is your choice.
I have a split rigging tube that I could pull off, exposing my rigging.
Using mini zip ties, I tied together my 3 extension wires to keep them in order and to make it easier to run along the rigging.
Once the wires were laying in position, I used large zip ties to secure them to my rigging.
I then ran my SDS wire extension harness in the rigging boot, into the boat, along and under the starboard side rail to my dash.

**** OEM Suzuki SDS adapter cable next step: You will need to cut the cable in half and then splice the OEM Suzuki SDS cable wires together with the extension you made in order to reach the Suzuki interface cable at the dash.
Some adapter cables will have a BLUE wire and a shielded wire (bare wire) when you cut the cable in half. These do not need to be connected.
Make sure to add solder to bond the connections and then cover the bare wires with heat shrink.

*** diy SDS adapter cable: This is your SDS wire harness and at this point you will need to crimp your wires to the pins and insert them into 1 of the connectors that will be connected to the female Suzuki SDS wire harness and the other end will go to the Suzuki interface cable at the dash.

Next run your SDS extension cable to your dash and connect it to the Suzuki Interface cable.
**Note there is a 2nd wire hanging off of the interface cable, zip tie it to the main cable as it does not get used.

Then build your backbone and add the terminal ends on the sides.
**One important thing to know is the Power wire, in my case Garmin uses a Yellow cable, must be connected in the middle “T” connection.
Then connect the Suzuki interface cable to one “T” and then connect your units, in my case my Garmin unit, NMEA 2000 cable in the other “T” port and connect that cable to your NMEA2000 port on the back of your unit.

Next connect your units starter kits Ground and Power wire to your fuse panel.

Then turn on your unit and navigate to your NMEA2000 settings to set up your network.

You should now be able to view and see data once you either turn the ignition key on or turn your motor on.
