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.
