5. Protect each cable’s foil shielding from causing a short circuit

inside the Splitter (see Figure 4). Use heat-shrink tubing around
the jackets where the wires emerge from the cable. The tubing
must overlap the wires a minimum of 6mm (1/4"). Use a heat
gun to shrink the tubing.

6. Make the connections using the red butt connectors supplied.

Insert the end of a colored wire into one of the holes in a butt
connector (see Figure 5). Insert the matching colored wire from
another cable into the opposite hole. (It is not necessary to
remove the colored insulation.) With the wires pushed tightly
against the far inside wall of the connector, squeeze the red
button until it depresses using slip-joint pliers. Gently tug on
each wire to ensure that it is securely fastened. Repeat this
process until all the wires are connected as shown in the wiring
diagram (see Figure 6).

NOTE: One of the butt connectors will be used to connect the
three bare wires. (Each connector has 3 holes to accommodate
up to 3 wires.)
NOTE: The red wire from the sensor cable will be connected to
the red wire from the NMEA 2000 cable. Likewise, the black
wire from the sensor cable will be connected to the black wire
from the NMEA 2000 cable. Do NOT connect the red and black
wires from the NMEA 0183 cable.
