Wiring Instructions
The wire harnesses for all kits are made identical. Some installa-
tions will have excess wire. All excess wire can be placed back into
the tongue when assembly is complete.
Diagram G is a wiring diagram showing what colors wires are con-
nected together for the brake system to operate properly.
Each wire harness section is identified by number as indicated on
the schematic drawing Diagram G.
1. Locate wire harness No. 5110488. This harness is used to at-
tach the 7-prong tongue harness to the lights on the trailer. Insert
the wire harness into the front of the tongue. Pull it through the
tongue and out the rear through the hole provided in the tongue
cover. Connect the harness to the wire harnesses in the trailer side
frames. Note that the two- single brown wire leads will not be used
in this application. The connector plugs on these two single brown
wires must be taped and then placed inside the tongue. See Dia-
gram G. Leave the front of the wire harness No. 5110488 out the
front of the tongue until directed later.
2. Locate wire harness No. 5110522. Note that one end of the
harness has a violet and brown wire connected at a female plug.
The individual wires in this harness are taped together at various
locations. Cut the tape attaching the violet and brown wire that are
joined at the female plug the same distance as what the brown wire
is long. (Approximately 30”).
3. Attach the violet wire from the positive side of the battery to the
plug attaching the violet and brown wires in harness No. 5110522
just described.
4. Pull this brown wire, and the remaining single bullet plugs, black,
blue, and another brown wire through the hole in the tongue cover
in the back of the tongue and out the front of the tongue. The end
of the harness that has the double plugs must be to the rear of the
tongue when properly installed and will be connected to the actua-
tor at a later time.
5. Route the two brown wires from the breakaway down through
the hole in the top of the tongue and out the front of the tongue.
Connect the two- single brown wires of harness No. 5110522 to
the wires from the breakaway switch. Note that either wire from
the breakaway switch can be plugged into either brown wire in the
harness. The remaining black and blue wires will be attached to the
tongue harness at a later time.
6. Locate the tongue harness with the 7-prong plug supplied in the
kit. Insert the end opposite of the 7-prong wire harness into the hole
in the top of the tongue that the original wire harness was removed
from. Pull the wire harness out of the front of the tongue so they
can be connected to the other harnesses.
7. Connect the wires in the 7-prong tongue harness with the wires
in harness No. 5110488 and 5110522 just installed. Mate the cor-
rect color wires as shown in Diagram G.
8. Route the white ground wire to the side of the tongue. Secure
the grounding ring on the wire to the tongue with a No, 10 self-tap-
ping screw.
9. Route the remaining wire harness No. 5110522 down the side frame
of the trailer to the actuator. Note that the kit has split plastic conduit
and plastic ties to hold and secure the wires. The wires can be attached
to the frame with the brake line clips provided in the kit to keep them
attached to the aluminum frame. Note that the harness No.
5110522 harness is a universal harness that has plug connectors
on it. These plugs are to be cut off and the wire cut to the required
length to attach them to the leads from the actuator. Cut, strip the
coating on the wires approximately 5/16” and mate the ends of
harness No. 5110522 to the actuator wires as shown in Diagram G.
Attach them together with the butt connectors that are already at-
tached to the leads on the actuator. Tape all connections just made
with electrical tape.
10. Once all connections are made, push any excess wires into
either the tongue or the side frame of the trailer. Place in the rubber
grommets either removed or supplied in the kit to protect the wires
from fraying when the trailer is towed.
11. Wiring should now be complete. Retighten the rear bolt that at-
taches the tongue cover and holds the tongue into the frame that
was loosened earlier to assist in the installation of the wires.

Installation Instructions for Steel Trailers with a
GVWR (Gross Vehicle Weight Rating) Less than
6,000 lb.
Use Kit No. TA0016
Removing the existing actuator from the tongue.
1. Unthread the tongue brake line fitting from the coupling connect-
ing it to the frame brake line tubing.
2. Loosen the rear tongue bolt attaching the tongue and tongue
cover to the frame. This will allow you to move the tongue cover
while installing the new wire harnesses into the tongue. NOTE:
ALL NEW WIRES USED IN THE INSTALLATION WILL HAVE TO
BE PLACED THROUGH THE HOLE IN THE TONGUE COVER.
3. Remove the bolts attaching the existing actuator to the tongue.
The complete unit can be now be removed pulling the tongue brake
line tubing out of the front of the tongue.
4. Remove the safety chains from the tongue. The new safety
chains supplied in the kit will be installed.
5. Unplug the tongue wire harness from the frame harness using
the plug-in connectors. It will not be used in the new installation.
IMPORTANT
Note: The bolts in the kit used to attach the coupler and safety
chains on all trailers are stainless steel. Also the U-bolts for
attaching the mounting brackets for the actuator and the bat-
tery boxes on the aluminum trailers are stainless steel. They
require that you use the appropriate size nuts with the nylon
inserts. It is also recommended that you use an anti-seize lu-
bricant (Supplied in the kit) on the threads before the nuts are
installed to prevent seizing when they are tightened. All other
U-bolts in the kit are plated steel and are used on the steel
frame trailers. The standard flange lock nuts are used on these
U-bolts.) Failure to mate the proper nuts with proper U-bolts
will cause the nuts to freeze when tightening thus preventing
the U-bolts from tightening properly.
