Tow Ready Trailer Break Away Kit Installation

Video Transcript for Tow Ready Trailer Break Away Kit Installation

Today we are going to cover the installation of a breakaway kit. The function of a breakaway kit is in case the trailer unfortunately breaks away from the truck or the car. What will happen is the breakaway kit will pull a plunger, basically an electrical switch, that will send power via the battery to the brake axles so the trailer wont be free to run off into the ditch, and it will just slow down the trailer as soon as possible. That is the function of a breakaway switch. And now we will go ahead and install one. What we have here is basically a trailer frame, obviously not a whole trailer. But we are going to cover this as a generic install. No matter what brand you are using, they all install pretty much the same way. In this demonstration we will be using a part from Tow Ready, Part Number 20048.

To begin your install, basically you will want to find a good place to install your battery box. In this case, we are going to install it on the frame here. Just make sure you have room for any weight distribution or sway control materials that are going to be installed on the trailer, too. This box can be mounted basically anywhere on the trailer. You can mount it inside the trailer Ive seen that before. You can mount it on the outside on the body or generally on the bottom. A lot of people do that. But for clarity, we are just going to go ahead and mount it on the frame here. This will give you an idea of what is going on. This one bolts right onto the frame, so we are going to attach a screw here and screw here. It does come with four holes but the frame is not big enough. But this will work out for us just fine.

Next we are going to install the breakaway switch itself. We are going to mount this on the frame here on the side. You can mount it on the bottom or virtually anywhere else it is more convenient, as long as it does not get messed up by dragging on the bottom or getting caught in the safety chain. So anywhere that is safe and out of the way, you can mount it. So we are going to go ahead and mount it on the side here. So that is simply all it takes. This will be connected to your hitch eventually, on the vehicle. Then we will go ahead and run these wires up here to the battery box. Next we are wiring the brake switch itself, and that connects to the blue wire or the brake wire on your trailer. It does not matter which wire, it is just a single line with a switch in the middle. One will go to the blue wire and one will go to the battery itself. What we are going to do is go ahead and splice inside here and make our connections and then we will run the other lead straight to the battery. Honestly, the best way to do this is wire it to a junction box but sometimes you do not have one of those, so you can just add it straight in just like this. Then find the brake wire on your trailer. Typically it is blue, but it may be different, depending on the manufacturer of the trailer.

But in our instance we are going to go ahead and use the blue wire. Take one of the free ends of the brake switch wire and just attach it to the blue. And you can do this any way you want. In our instance we are just going to use a regular quick splice, but you can cut it, wire net it as long as you can secure a live connection it will work. And the other wire we will attach to the positive side of the battery. There is a little slot inside of the box here. And you just hook it up to there. And that is it. For a breakaway switch, that is all that is required. Now for our particular part number here we need to make one more connection to the battery. It comes with a little special device that allows you to hook up two cables to the positive side of the battery. And we will show you that a little later. Next thing we are going to do is go ahead and install the ground wire for the charger itself, which is sitting right here. And you can do this two different ways. The way we are going to do it is run it straight from the frame for ground. However, some trailer wiring does have the ground wire run through the cable up to the lights themselves, kind of bypassing the brake switch wire, and just making a connection that way. I think it is easier, a little bit less connections in the wiring, if you just go ahead and ground it to the frame. We are just going to put a little ring terminal on here, and you just want to screw it right into the frame. If your breakaway kit did not come with a charging circuit then you are pretty much done at this point. You have just got to make that final connection to the battery. However, in this case we do have a charging circuit so we are going to go ahead and install that.

The charging circuit on this particular model is the yellow wire here, and it has to go to a constant 12 volt source. Again, check with the wiring on your trailer because it does vary according to manufacturer. Typically it is a black wire or red wire for a constant 12 volts. In our situation it is going to be a black wire, so we will go ahead and make our connections to that. All right, next we will make our final connections to the battery. As we said before, there are going to be two coming from the positive post in the battery, and this simple device that comes with it will just slide onto it. And then it will slide on the cord that goes to the breakaway switch. According to the manufacturer, the wires will be labeled which one is positive and which one is negative. In this case, it is going to the red wire. The red wire will go back over here and then the black wire goes to our ground post on the battery. And when you have those connections made, you can go ahead and close it up. Plug it up to your vehicle and make sure everything is working. You might need to charge it, you might not. Press the button and find out. In our case the battery is fully charged, so we do not need to worry about that. In our case, we are going to hook up a tester to our brake lead and activate the breakaway switch to make sure it functions as it is supposed to. Next we will pull the plunger out of our breakaway switch somewhere in our brake line here in our case, blue you should see power coming out the other side. So that is working since the switch has been activated. We will double-check ourselves by putting the switch back in and making sure it goes back off. And it is off. So the system is working as it should. That concludes our install of a Breakaway Kit, using Part Number 20048 from Tow Ready

Unusually good service I had technical questions and received answers within a very short time. Delivery was quick and arrived in good shap. Unfortunately, one of the few that do what they say. I'll be back. I'm refurbishing a horse trailer so I haven't installed the product yet.5696

  • Breakaway Diagram Without the Charger
  • You are correct, of the 3 positive leads from the break away system battery, one taps into the 12V lead from the trailer connector. This is what keeps the battery charged. One lead is grounded, and the other attaches to one lead on the breakaway switch, with the other lead tapping into the brake output wire. When the pin is pulled out of the break away switch, the circuit is closed, and 12V is sent from the battery to the trailer brakes. With the pin remaining in the switch, the brakes will oper

  • Could Road Debris Pull the Pin on Trailer Breakaway System
  • Once the pin on the break away switch is pulled, the brakes on the trailer will engage. I have not heard of this occurring, but it is possible. I would recommend routing the cable that pulls the pin as close as possible to the trailer frame. You can use a few strips of electrical tape to hold the cable in place so that it is not hanging down and easily snagged. If the trailer should come loose and the safety chains should fail, the tape would not prevent the cable from pulling the pin and eng

  • Where Does the Cable for the Break Away Switch Attach on the Tow Vehicle
  • The cable loop for the breakaway switch in the Tow Ready Trailer Break Away Kit With Built-In Tester and Battery Charger, # TR20048, does not attach to the ball. Run the pin through a safety chain loop on the hitch. Pass it through the loop on the other end of the cable, and then plug it in to the break away switch.

  • Where to Attach the Electric Brake Emergency Break Away Cable When Towing with a Fifth Wheel Hitch
  • There are many options for attaching the breakaway cable from the Tow Ready Trailer Break Away Kit, item # TR20048, to your vehicle (video linked below). You could attach to a tie down point in the bed of your truck or you could use stake pocket tie down and attach the cable to it. You could also run the cable down to the safety chain loop on the bumper hitch if your vehicle is so equipped. Finally, you could attach the cable to the rails installed in the bed of the truck.

  • Is there a Capacity Requirement for Safety Cable Attachment to the Vehicle for a Breakaway System
  • The connector used should be capable of pulling the pin from the switch at any reasonable angle. You will also want it to be secure enough that you will not lose the cable and pin in the unfortunate event of a breakaway. Many people just put the cable through the chain loop on the hitch and then run the pin through the small loop in the end of the cable. This secures the cable to the hitch and no other parts are needed. In this configuration you need to mount the switch close enough to the c

  • What Type Of Clip Is Used To Attach The Cable Of Tow Ready Breakaway Kit # TR20048 To The Vehicle
  • The Tow Ready Trailer Breakaway Kit, part # TR20048, does require a pretty good pull on the cable for it to come out of the breakaway switch. It is designed to be able to be pulled out when the trailer becomes disconnected from the vehicle, but not when there is just a light pull from any small object that might interfere with the cable. They do not list a pulling strength on the cable of the breakaway kit. Many people just put the cable through the safety chain loop on the hitch and then run

  • When Would a Trailer Break Away Kit Be Required By Law
  • Many states in the U.S. and provinces in Canada require break away kit. In order to determine the specifics for where you live and where you plan to travel, you can check with the state and federal departments of transportation for the area. Specific weights or trailer types may change from state to state, so it is important to check for every state in which you plan to be towing. A break away kit is just a good idea in general, whether it is required or not. It is a fairly simple system. If

  • After Installation of Tow Ready Trailer Breakaway Kit # TR20048 Light is Not Working
  • On the Tow Ready Trailer Breakaway Kit, part # TR20048, when you push the test button the green LED will light if the battery is over 12 volts. If the battery is less than 12 volts the red LED will light. If the battery is below 6 volts, neither LED light will illuminate. That would indicate a dead battery. I would also recommend to check the wiring of your breakaway kit. I am including a link to a video of the breakaway kit being installed. 1 - Connect one black wire from the breakaway

  • How to Release the Brakes on a Trailer Once the Break Away Switch Is Activated
  • If you still have the plunger end that goes in the break away switch, then you can simply insert the plunger back into the switch and that should cut off the power to the brakes on your trailer. If you no longer have the plunger, then you can either remove the break away battery or cut one of the wires going to or from the break away switch. One wire is coming from the break away battery and the other is going to the brake circuit on the trailer. Cutting one of those wires will terminate the

  • Troubleshooting Trailer Break-Away System on Camper
  • It sounds as if your breakaway system is not functioning. On a properly working system, the brakes would engage regardless of whether or not the 7-way was plugged into the vehicle. It is not necessary to have an additional break away battery if the battery on your trailer has sufficient power to keep the brakes applied for 15 minutes once the break away pin is pulled. I would recommend replacing the switch assembly with part # 2005-P and checking how the system is wired. You can take a loo

  • Trailer Brakes Work with Break Away System But Not with Brake Controller
  • It sounds like the brake controller might need to be reset or the wiring from the vehicle side to the break away system needs to be examined. Try adjusting the power output of the controller. If that does not work you can test the controller itself using a circuit tester like # 3808 if needed. Sever the blue wire a few inches from the back of the controller and use the circuit tester to test the end coming from the controller while applying the manual override. If it does not show power then

  • Troubleshooting a Breakaway Kit that Applies Voltage on Trailer Brakes All the Time
  • It sounds like you may have wired your setup in such a way that the battery is somehow putting voltage on the brake output circuit which is why your brakes are locking up. Check the third page of the installation instructions I attached to see the wiring diagram on how it should be wired up and compare it to your setup. You should also check to make sure that the plunger is properly installed into the switch.

  • Testing Trailer Brake Magnets With Full 12V Power Supplied Using the Brake Controller Override
  • In order to deliver full 12 volt power to your brakes while performing a pull test you can also use the override functions on your brake controller. This will avoid installing any switches, or disturbing any of the existing functional wiring. Switches can be forgotten, and additional connection points or unnecessary splices of the breakaway system can lead to problems like corrosion down the road. To use the override function on your brake controller you would turn the power of the brake con

  • Replacing Break-Away System Pin on Travel Trailer
  • If the same company that manufactured your break-away switch manufactured the cable/pin kit you purchased, the new pin should work fine. If the pin and the switch are from different manufacturers, the pin most likely will not fit. When you pull the old pin to replace it with the new one, the brakes will indeed apply, but they should let loose when you insert the pin back into the switch.

  • Brake Controller Does Not Detect Trailer when Breakaway System is Connected
  • The most common issue with breakaway systems occurs because of the wiring. They do not always make it as straight forward as it could be. Starting from the trailer side connector the brake output wire will go to the brakes and to the breakaway switch. The other wire from the switch will go to the brake output wire on the breakaway battery. The power wire to charge the breakaway battery will connect to the 12 volt wire from the trailer connector. And the battery ground wire should be grounded

  • Troubleshooting Weak Trailer Brakes and Breakaway Switch that Doesn't Work at All
  • It sounds like you need to check the trailer braking system out. I would start by making sure that the connectors on the vehicle and trailer are connected properly, and that there is no corrosion in either of the connectors. Corrosion can rob power from the trailer brakes especially because the trailer brake circuit is in the lower position in the connector and next to the ground wire. Using some dielectric grease, item # 11755, in the connection can often help a great deal. Make sure that th
