making sure that the wires do not rub or get pinched.
Fasten wire(s) to the boat at least every 18 in. (45.72
cm) using appropriate fasteners.
• Using existing Round 10-pin BOAT
harness connector
Pin-4 = Buzzer
Pin-9 - MIL or Check Engine Lamp
Verify that connections exist at the helm. If not,
two new wires will be required between the helm
and pins 4 (MIL) and 6 (Buzzer) of the Engine
harness 8-pin Deutsch connector.
• Using existing Rectangular 8-pin BOAT
harness connector
* Requires two additional wires for the MIL and
Buzzer. The MIL is connected to pin-6 and
the Buzzer is connected to pin-4 of the Engine
harness, 8-Pin, Deutsch connector.
• Using the Crusader boat harness (P/N
RA121092/RA121092A), the MIL is wired at
the helm to the Green/Yellow wire and the
Buzzer is wired to the Tan/Black wire.
• If previously equipped with the Optional
Crusader Warning Light Cluster P/N 23505:
Figure 17 Optional Warning Light Cluster - Crusader
Part No. 23505
When installing the Sync-N-Cruz harness, route the
harness back to the Master engine, making sure that the
harness does not rub or get pinched. If an extension
harness is required, be sure to secure the connection
properly. Fasten harness to the boat at least every 18
in. (45.72 cm) using appropriate fasteners.
MASTER/SLAVE WIRING CONNECTION
This connection allows the CAN Bus data lines to be
joined together for dual engine applications.
The benefi ts of a Master/Slave connection are:
• Allows for twin engine Sync-N-Cruz operation.
• Electronic Engine Monitor systems installed at
the helm area may display engine data for both
engines.
IMPORTANT: In dual engine applications, the
master/slave wiring harness is used to connect the
engines together. One end of this harness has one
more wire in it than the other end. The end with the
extra wire is plugged into the Slave engine harness.
This extra wire is then attached to the ground stud
on the Slave engine.
ENGINE WARNING KIT (OPTIONAL)
An engine warning kit, RK179008, is available. This kit
contains a Check Engine Lamp and Warning Buzzer.
It is recommended that the boat be equipped with a
Check Engine Lamp (Malfunction Indicator Lamp - MIL)
and buzzer. These devices warn the boat operator of
potential engine problems.

Some boat wiring may already support these devices
and/or they may already be installed at the helm.
Ensure that the new connections match up to the
existing boat wiring and warning devices.
Ensure the light and buzzer wires are in the existing boat
harness, otherwise new wires will have to be run from
the helm to the engine. Use 18 ga minimum wire size,
The Check Engine lamp, of the cluster, and
the existing Buzzer may be used with ECM-07
engine models.
(1) At each engine, locate the Warning Cluster
Harness, 8-pin connector. The wires at Pin-A
(Orange/Tan wire, Check Engine Lamp) and
Pin-B (Tan/Red wire, Buzzer) will be the only
wires used. Cut the 8-Pin connector off of the
harness and tape back the wires not used.
