Tongue Harness Retro Kit for 95/150 Aluminum Trailers
The new wire harness for the SL95AL and SL150AL trailers is designed so there is a positive ground system (white wire) that is connected
directly to the actuator eliminating any grounding through the frame to operate the actuator. The lights for the trailer still rely on the trailer
frame for its grounding.
ASSEMBLY INSTRUCTIONS
Remove the following from the trailer:
• Remove the boat from the trailer.
• Mark the winch post where it is located on
the tongue. It will be mounted in the same
position once the retro kit has been completely assembled. Remove the winch
post assembly.
• Remove the two battery boxes from the
side frame of the trailer.
• Remove the lids from the battery boxes,
disconnect the wires from the batteries.
• Remove the mounting screw that secures
the breakaway switch to the tongue.
Installation of the Wire Harness
• Cut the blue, black and white wires approximately 2” behind the black shield.
• Unplug the two wires from the breakaway switch and mark with tape to identify for future connections.
• Unplug the violet and blue wire from the
tongue harness. Cut the wire leads from
the BrakeRite actuator at the butt-splices. Remove these wires from the trailer
tongue and frame, then discard. Cut the
white ground wire also. Remove the
ground ring that secured with one of the
mounting bolts. The BrakeRite actuator
will be connected with the new wire harness being installed.
• Locate the red, yellow and green wires
that have the male bullet plugs on them.
These wires power the lights on the trailer. Disconnect the plugs, secure wires
so that they will not slip back into the
hole in the top of the tongue. They will
be reconnected later.
• Disconnect the brown front side marker
lights by unplugging the connection.
• Disconnect the white ground wire from
the tongue by removing the screw in the
white grounding ring.
stripped on the existing section of wire
harness. Connect together by crimping
the butt connectors already attached to
the wires of the new wire harness section.
• Locate the two black wires from the
breakaway switch that were marked
with tape. Cut the plugs off the ends of
the wires and strip the ends 3/8”. Connect one of the wires to the violet wire
of the new wire harness and the other to
the black wire of the new wire harness.
• Heat the shrink connections with a heat
gun or other means making sure the
wires are not overheated causing the
coating to melt.
Making the Wire Connections at the Top
of the Tongue
• Locate a 6” section of the ¾” heat shrink
• Locate the main wire harness coming
out the front of the tongue. It has the ¾”
black shield. Push it into the front of the
tongue so there won’t be any pressure
on the wire harness as it is pulled backwards into the tongue.
• Pull the wire harness out the hole in the
top of the tongue located directly behind
where the two side frames meet each
other above the tongue.
• Pull on the wire harness until approximately 8” of the black shield extends out
the hole.

tube. Slide it over the end of the black
shield until the heat shrink tube is totally
on the black shielding.
• Strip the ends of the blue, black, and
white wires approximately 3/8”.
• Locate the new section of wire harness
with the plastic loom. It has a tee located
closer to one end than the other. Inside
the plastic loom are three colored wires,
blue, black and white.
• Mate the blue to blue, black to black,
and white to white wires with those just
• Once all of the above connections have
been sealed, slide the ¾” shrink tube over
all of the connections so they are located
in the center of the ¾” shrink tube. The
three trailer light leads should extend out
past the end of the shrink tube.
• One end of the shrink tube should be located on the black cable shield while the
other end is on the plastic loom of the
new harness. Heat the shrink tube with a
heat gun or alternate source of heat. Do
not overheat.
Trailer Lights
• Reconnect the wires for the trailer lights.
Match colors: red wire of the tongue harness to yellow wire, green wire of tongue
harness to brown wire, and brown wire
of tongue harness to green wire of trailer
light harness. The connections must be
positive and completely connected.
• Reconnect the front side marker light
leads. Reconnect the white ground wire.
Note the white ground wire will now be
used for the grounding of the trailer lights
only. Once connected, the BrakeRite actuator will have its own positive ground.
• Pull the breakaway switch forward in the
tongue back to its original position and reattach using the screw removed earlier.
Connecting the Breakaway Actuator
• Slide the new wire harness section into
the tongue hole until the tee in the plastic
loom is at the tongue.
• Route the plastic loom down the side
frame of the trailer and over to the Brak-
eRite actuator. Route the plastic loom
behind the back side of the BrakeRite
actuator. The plastic loom will come out
on the rear side of the actuator for easier
connecting. Lay the plastic loom on the
bottom ange of the I-beam side frame.
• Slip another of the ¾” shrink tubes over
the end of the plastic loom until it is completely on the loom.
• Route the wires in the plastic loom over to
mate the wires from the BrakeRite actua-
tor. Note that the wires in the plastic loom
are staggered and positioned so they will
t inside the shrink tube once the connections are complete.
• Mate the colored wires as follows:
Wires from plastic loom Wires from actuator
Black 12 gauge Black 12 gauge
White 12 gauge White 12 gauge
Blue 16 gauge Blue 16 gauge
Violet 12 gauge Violet 14 gauge
Black 16 gauge Brown 16 guage
• Cut the wires from the BrakeRite actua-
tor to mate the connectors on the ends of
the mating wires inside the plastic loom.
Strip the wires back approximately 3/8”.
Insert the proper colored wires into the
proper crimp connectors and crimp.
• Heat the connections with a heat gun to
shrink the splice insulation around the
crimps.
• Slide the ¾” shrink tube over the connec-
tions just made so one end of the shrink
tube is over the wire restrainer on the actuator and the other end is over the plastic loom. Shrink in position using a heat
gun.
• Route the wire loom down the bottom
ange of the trailer side frame. Identify a
spacing distance that will retain the wire
loom in the side frame of the trailer when
in use. Drill ¼” holes evenly spaced down
the side frame just above the wire loom.
Note that the connector end will not slip
through the hole. Place the end of the
plastic wire tie around the plastic loom
then back through the hole. Insert the
end or the wire tie into the connector
end. Pull until the wire loom is secured to
the trailer side frame. Repeat this on the
remaining holes just drilled to secure the
complete harness in place.
• Connect the Break Away Batteries to
the new wire harness. (Note the battery
lead with the “Red” shrink tube is the positive lead and should be connected to the
positive side of the battery.)
Testing the System
• Check the system to make sure that proper connections have been made when
installing the wire harness. This can be
checked by pulling the break away switch.
When pulled, the system should function
and the brakes should activate.
• Once the system checks out, re-install
the Break Away Batteries and the cases
to the side frames. Tighten.
• Plug the seven pin plug into a test rig and
cycle the system to assure there is a satisfactory installation and the brakes are
being activated.
Installation is complete.
Reassemble the winch post to the settings
• Insert a plastic wire tie into one of the
holes from the outside of the frame.

marked earlier when it was removed. Place
the boat back on the trailer.
