Installation Guidelines for DTS System Components

To avoid the possibility of serious injury or death from loss of boat control, do not splice
or probe into any wire insulation of the DTS system. Splicing or probing will damage
the wire insulation allowing water to enter the wiring. Water intrusion may lead to wiring
failure and loss of throttle and shift control.
DATA HARNESS
To avoid the possibility of serious injury or death from loss on boat control, do not pull
on cable connectors when pulling cable into boat. Observe correct pulling procedure.
Pulling on connectors can loosen terminals resulting in open or poor electrical
connections. Open or poor electrical connections may result in loss of throttle and shift
control.
CONNECTORS
IMPORTANT: Connectors should never have to be forced into the receptacle. Ensure
that connectors are free of any lubricant or dielectric grease before installation. When the
connector is properly aligned, it will only take a small amount of pressure to insert it into
the receptacle. Rotate the locking collar to secure the electrical connection.
NOTE: Connect only one data harness of the required length between the engine and
helm. If a data harness is too short, do not connect multiple harnesses together to make
up the required length. For installations requiring a data harness length longer than
12.2 m (40 ft.), contact Mercury Marine for more information.

Data Harness Pulling Procedure

IMPORTANT: Do not route data harness near engine ignition components (coils, spark
plug leads, and spark plugs), high power VHF coax or radios. An electrical field generated
from these components could cause interference with data transmission.
IMPORTANT: Do not route data harness near sharp edges, hot surfaces or moving parts.
Fasten cables away from any sharp edges, fasteners or objects that could wear into the
harness.
IMPORTANT: Avoid sharp bends in the data harness. Minimum bend radius should be
7.6 cm (3 in.) for the final wiring installation.
