Easy Installation



           

Autowbrake Installation Instructions

We recommend having a dealer or installation professional install your Autowbrake Trailer mounted electric brake controller.

For those Do it yourselfers… 

Select mounting location

We recommend mounting close to the trailer junction box/ usually on the trailer frame, however other options are fine (ie: in cabinet, inside trailer etc.)  Autowbrake can be mounted in any direction and any angle for ease of installation.  Once you decide on the location it’s time to match up wiring. 




Wiring Instructions

Now familiarize yourself with your trailer’s wiring diagram. You will need to locate 5 wires. Check your trailer manufacturer’s operation manual.

Trailer Brake- Normally Blue

Power- Normally Red or Black/ (Brown depending on next step installation using running light option for power)

Ground- Normally White

2 brake wires (check trailer manual for brake wire colors)

Match these wires with the wires on the brake controller. (Now you are ready to install)

Connect all wiring (splice into harness directly if you are not able to get to a junction box or have a trailer with hard wiring harness only) We strongly recommend utilizing junction box direct for best use.

Locating brake light wires

Turn on tow vehicle ignition and plug trailer into vehicle just like you are ready to tow. Turn on vehicle hazard lights or have someone inside vehicle press and hold down the brake pedal.  Use voltmeter to locate brake light voltage and connect brake wires (green and yellow) on the Autowbrake controller.

Power connection Option 1

Leaving tow vehicle ignition on and trailer plugged into tow vehicle, test and locate the 12 volt power source (Red/Black wire, check trailer manual). Connect the Autowbrake power wire to this wire either at junction box as recommended or direct splice into trailer harness. Attach the other wires to their corresponding sources as recommended. (Trailer brake-Blue/ Brakes lights-Green and Yellow /ground-white)          

Power connection Option 2 

Leaving tow vehicle ignition on and trailer plugged into tow vehicle; turn on tow vehicle running lights. Use meter to confirm 12 volt source (usually brown wire, check trailer manual). Connect Autowbrake power wire to power source and the remaining wires to corresponding.(Trailer brake-Blue/ Brakes lights-Green and Yellow /ground-white)

Attention!! Utilizing Option 2 for a power source will require you to have running lights on while towing in order for Autowbrake to have power and operate trailer brakes.  We always recommend having lights on while towing (for safety and visibility), failure to do so could result in accident and or injury due to towing without trailer brake function. You must be sure to turn on your lights on manually while towing.           


Calibration Process

Calibration is required the first time you install your Autowbrake, or when relocating your Autowbrake to a different position or location on your trailer/ or moving to a different trailer.

Connect trailer to tow vehicle and plug in connections. Be sure to calibrate on a level driveway or parking lot, because this allows Autowbrake to determine what the common towing position will be. It is determining a new level relative to the tow vehicle.  Safety note: Chock tires and only turn vehicle ignition to ignition on position only, you do not need to start tow vehicle and leave it running.

Two Person Calibration Process

Have one person get in the vehicle and press the brake pedal (turn vehicle ignition to on position and trailer harness plugged into tow vehicle).  Have them continue to hold brake pedal down. While the brake pedal is depressed, have the other person go back to Autowbrake and depress both buttons at the same time for 2 to 4 seconds then release.  Once the LED tops flashing you can release the brake. Your Autowbrake is calibrated.

How to check the Autowbrake current setting.

Press gain button for 2 to 4 seconds. Flash settings:

Setting 1:  1 slow flash 3 times in a row

Setting 2:  2 slow flash 3 times in a row

Setting 3:  3 slow flash 3 times in a row

To change the power settings have one person press vehicle brake pedal. Other person presses the gain button for 2 to 4 seconds to change settings. The Autowbrake LED light will flash showing you the setting. (Flash counts above)


One Person Calibration Process

So if you are doing this whole thing on your own, you will want vehicle ignition on the trailer plugged in. Turn on vehicle hazards lights.

Walk to Autowbrake controller and when hazard light flashes on, press both buttons at the same time for 2 to 4 seconds (you will want to time this with the hazard lights so the buttons are pressed at the same time the hazard lights go on… yeah kind of tricky but you can do it) remember …hold down for 2 to 4 seconds then release the buttons. Once the LED stops flashing the Autowbrake is calibrated.

How to check the Autowbrake setting.

Press gain button for 2 to 4 seconds. Flash settings:

Setting 1:  1 slow flash 3 times in a row

Setting 2:  2 slow flash 3 times in a row

Setting 3:  3 slow flash 3 times in a row

To change the power settings, turn the hazard lights on, when hazard light flashes on, presses the gain button for 2 to 4 seconds to change settings. The Autowbrake LED light will flash accordingly. (Flash counts above)

Recommended Settings

Setting 1- Smaller travel trailer, Utility trailer, small equine and flatbeds (empty). Up to 3500 pound range

Setting 2- over 3500-6000 pound trailers, utility, equine and flatbeds (loaded).

Setting 3- over 7000-12000 pound trailer however Autowbrake will work on 3 axle trailers up to 14000 pounds.

NEVER exceed your recommended tow vehicle capacity!  


What this Key Fob for ???

Once you are all hooked up and ready to go…. You wonder if all is well and working right.

So get yourself ready about 10-15 mph (make sure your lights are on…for safety, visibility and especially if you used power option 2 as the controller power source). Press the key fob button while you are driving and you will feel your trailer brakes pulse slowly…..feels like slow motion ABS…..you are connected and Autowbrake is on and braking.

Now go enjoy your trip. 

We appreciate your business. Autowbrake. We Are Right Behind You!
