Introduction

The Sway Command™ Tow Control system is a self-contained

trailer stability control module that detects undesirable trailer

movement from external sensors and mitigates it by adaptively

applying a variable braking voltage to the left and right trailer

electric brakes. This system is currently only for use on travel

trailers.

The Sway Command™ Tow Control system uses sensors

to detect excessive trailer sway. The system activates

automatically and applies voltage proportional to the amount

of sway detected to the electric trailer brakes. This dampens

the sway and slows down the trailer. When excessive sway

is detected, the light pod will blink red and the tow vehicle

operator may feel the trailer brakes activate until the sway is

dampened.

Causes of Sway

• When the tongue weight is less than 10% of the trailer’s

weight, it has a natural tendency to sway.

• Improper weight distribution hitch adjustments.

• Crosswinds.

• A transfer truck passing from the rear of the trailer.

• Descending inclines.

• Towing speeds.

• Tow vehicle not properly matched for the trailer.

• Improper loading, overloading and poor weight distribution on

the trailer.

• Incorrect tire inﬂ ation.

Always inﬂ ate tires per

manufacturer’s speciﬁ cations. In

addition to causing sway, improper

tire inﬂ ation may cause premature

tire wear, poor handling, reduced

fuel economy or blowouts. Check tire

inﬂ ation weekly when the tires are

cold before operation.

Note: The Sway Command™ System is not a replacement

for using sway control bars when towing a travel trailer.

Sway control bars should be used in conjunction with

the Sway Command™ System.

Preparation

Resources Required

• (4) 1/4” washer hd lag

screws

• (2) #8 x 1” phillips hd

screws

• Screw gun and drill

• #2 phillips screw bit

• 1 1/4” hole saw

• 1” wide butyl tape x 12” long

• Wire Crimpers/Strippers

• 3/8” socket bit for screw gun

• 3/8” socket and ratchet

• Putty stick

• Hook tool or awl with bent

tip

• #10 10-12 GA Ring terminal

Installation

1. (Fig. 1) shows the Sway Command™ controller and the light

pod. Locate the Sway Command™ light pod sticker on the

front of the trailer (Fig. 2).

Note: The Sway Command™ controller will be referred to as

“the controller” for the remainder of these instructions.

2. The sticker (Fig. 2) identiﬁ es the mounting location for the

light pod. A 1 1/4” hole will need to be drilled in this location.

Do not drill the hole completely

through the front wall: drill only

through the sheet metal/ﬁ berglass

and the wood backer immediately

behind it.

3. Drill the 1 1/4” diameter hole using the center circle on the

sticker as your guide (Fig. 3).

4. (Fig. 4) shows the ﬁ nished hole drilled only partially through

the wall. There is a wire and connector inside the front wall

that will be damaged by drilling too deep.

Note: If the coach has an outside storage door (on the

roadside sidewall) at the front of the trailer, look inside to

check for a wire harness with a connector for the light pod.

If there is a harness that connects to the light pod, when

the hole is drilled in Step 3 (Fig. 3), the hole needs to be

drilled completely through the front wall and into the storage

compartment.

5. Fish out the wire and connector inside the front wall (Fig. 5)

using a hooked tool (such as a bent awl) to reach up in the

wall.

6. Prep the back side of the light pod with butyl tape as shown

(Fig. 6 and 7).

7. Plug the connector on the light pod to the one ﬁ shed out of

the inside of the wall (Fig. 8).

8. The connector and wiring should be tucked straight up inside

the wall, away from the mounting screws for the light pod.

9. Place the light pod over the sticker with LEDs facing upward

as shown (Fig. 9). Secure the pod to the front wall using two

#8 x 1" screws (Fig. 9).

10. Trim all the excess butyl tape from around the light pod

(Fig. 10).

11. The controller should be mounted as high up on the front

frame rail as possible, and within 6 inches of the centerline

(Fig. 11 and 12).

Note: In some cases the spare tire is mounted inside the

A-frame leaving insufﬁ cient space for the controller on the

front of the frame rail. A bracket has been provided behind

the front frame rail on which to mount the controller.

Note: The controller should also be mounted in as level a

position as possible.

12. Secure the controller with the four 1/4" hex head lag

screws and the 3/8" socket bit (Fig. 12). DO NOT over-tighten

the screws as this may cause the controller housing to crack.

Unplug the large harness from the controller.

13. Remove the cover on the junction box next to the A-frame

rail (Fig. 13). There is a 20A breaker beside the wire junction

box (Fig. 14).

14. There are 3 wires on the controller harness (black, blue

and white). Strip back the black wire (1/4”), and install a #10

10-12 GA ring terminal on this wire.

15. Attach the black wire to the protected side stud (should be

silver if the breaker is installed properly) of the 20A breaker

located beside the junction box (Fig. 15). Use a 3/8” socket

to remove the nut from the circuit breaker stud and re-tighten

it after the terminal is added.

16. Loosen the strain relief on top of the junction box and insert

the blue and white wires from the controller harness.

17. Re-tighten the strain relief screws. Remove the large blue

wire nut from the bundle of white wires inside the junction

box (Fig. 16).

18. Add the white wire (stripped to 3/4”) from the controller

harness to the white wire bundle and re-install the blue wire

nut.

19. Locate the group of blue brake wires connected with a

copper crimp connector or wire nut (Fig. 17).

20. Cut off the copper crimp connector, strip wires 9/16” and

connect with the red wire nut.

21. Attach the blue wire from the controller harness, to the

group of blue brake wires with the red wire nut (Fig. 18).

22. Tuck the wires inside the junction box and re-install the

lid on the junction box. Ensure no wires get pinched while

reinstalling the lid on the junction box. Locate and pull down

the small harness under the front of the trailer (Fig. 19).

23. Plug the large harness into the controller and plug the

small harness (Fig. 19) into the small connector on the

controller harness (Fig. 20).

Prior to Operation

Failure to follow the guidelines

below may result in death, serious

personal injury, or property

damage

1. Sway Command™ must be installed as detailed in the Sway

Command™ Installation section. Sway Command™ will not

operate correctly if improperly installed.

2. Trailer brakes must be adjusted per OEM speciﬁ cations to

ensure proper trailer braking. The tow operator must ensure

trailer brakes are properly adjusted. Sway Command™

may not operate properly with improperly adjusted brakes.

Discuss brake adjustments with the trailer OEM.

3. Trailer brakes must be burnished to ensure proper trailer

braking. New electric brakes may contain a coating to

prevent rust during shipping. An unburnished brake will

reduce trailer braking capacity. The tow vehicle operator

must ensure trailer brakes are properly burnished to ensure

brakes are effective in slowing the tow vehicle. Sway

Command™ may not operate properly with improperly

burnished brakes. Discuss brake burnishing with the trailer

OEM.

4. Improperly adjusted tire pressure can reduce braking

effectiveness and can be a source of sway. Tire pressure

must be adjusted to the tire manufacturer’s recommended

pressure.

5. Tires must have useful tread life left to ensure proper

braking. Tire tread below useful life could skid during

braking. The tow operator must ensure tires have useful

tread left.

6. Improperly loaded trailers can be a source of sway. At

higher speeds, if the trailer naturally sways, the tongue

weight and/or trailer weight distribution must be adjusted.

Sway Command™ could activate frequently in this situation

causing excessive brake wear. Ensure proper hitch tongue

weights are observed for the trailer.

7. The tow operator must ensure Sway Command™ is

operational by observing the Sway Command™ light pod

status. Ensure the light pod is illuminated green. See Sway

Command™ Status light for status other than green.

8. The operator should operate the tow vehicle safely as

driving and weather conditions allow. Sway Command

relies on braking and tire grip to mitigate sway, and overall

effectiveness of the system may be reduced or impaired in

slippery/icy driving conditions.

Operation

1. When Sway Command™ detects excessive sway, the light

pod will blink red and the tow operator may feel the trailer

brakes activate until the sway is dampened.

2. Sway Command™ will “wake up” if it senses external brake

activations. During wake up, Sway Command™ performs

self-checks and alternately ﬂ ashes the light pod lights green

and red.

Note: The Sway Command™ light pod will be green if no

issues are detected. If an issue is detected, the light pod will

blink green once, followed by a number of red ﬂ ashes. See

troubleshooting for a description of the various blink codes.

3. Sway Command™ will enter a low power mode after 10

minutes when it senses no tow vehicle brake activation or

movement. The Sway Command™ light pod will turn off

when it powers down.
