Video Transcript for Tekonsha Trailer Breakaway Kit 420000 Review
Today, we're going to be taking a look at the Tekonsha Replacement Breakaway Switch. Now, a breakaway switch is designed to apply power to the trailer brakes, to stop the trailer should it become disconnected from the tow vehicle. If the trailer and vehicle disconnect, the vehicle pulls on this cable right here, which pulls the pin out of the switch. Once this happens, the trailer brakes are applied, which will bring the trailer to an eventual stop. The kit is going to come with the switch. It's going to come with the wiring. It's going to come with the pin.
It's already installed there, and it's going to come with the cable. It's already attached. The wire leads on this side, these are going to measure 48 inches, or 4 feet long. One wire gets connected to power, the other wire gets connected to the electric trailer brakes. On this side, we're going to have the cable.
This is a high-strength, steel cable that's covered with a protective coating to keep it from fraying and to keep it from scratching anything that it comes into contact with. Now, this unit is designed for 1 to 4 axle trailer brake systems. The cable length is going to measure 48 inches or 4 feet long. It's got the looped end on here, that would connect to the tow vehicle. When it comes to the dimensions of the switch, it's really nice, low-profile design. This is going to give us an overall length measurement, and I am including the bracket.
From edge to edge, we're looking at about 4 7/8 inch long, and that's measuring from the end of the bracket to the end of the pin. The switch body, that's going to give us a measurement of about 3 inches long. The overall width, you can see that the switch kind of hangs out over the side a little bit, so the overall width is right around 1 7/8 inch. Just that bracket width is going to be about 1 1/2 inch. Then, the height, or the thickness, it's only about 7/8 of an inch. It does have a mount hole right here.
That's going to give us a diameter of 1/4 of an inch, and hardware is not included to get that mounted to the trailer frame. That's going to do it for today's look at the Tekonsha Replacement Breakaway Switch.

Purchased this switch to replace old rusty unit on our cargo trailer. I checked function with volt meter prior to installation and it works as advertised. Quality seems to be very good. It's one of those things you have to have but hope it never gets any opportunities to perform! Good customer service and prompt delivery. No problems.

No problems. Unit is holding up well and dont foresee any problems.
by: David P04/02/2020
etrailer products and service are excellent! With their helpful videos and staff (plus a little help from Curt Manufacturing and our teardrop trailer manufacturer (CampInn)) I was able to install electric brakes on the trailer, and a controller in my vehicle by myself. I had never installed electric brakes before. Everything works perfectly!
by: Dean06/01/2016
Good product, simple and works. Used this to replace the original brake switch due to it breaking. Wired to a small 12V breakaway battery then to Blue brake wire on the car trailer and all works as it should.

This item was exactly what I needed. The etrailer site was so easy to navigate and the selection of items cannot be beat. Whether you are looking for a component or a complete kit, they seem to have it all.

- Wiring a Replacement Breakaway SwitchI can help you wire the Replacement Tekonsha Trailer Breakaway Switch # 420000 and the accompanying diagram shows exactly how it will be wired; I have also added a link to a video which shows it being installed. The white wire is a ground wire and the other two wires are interchangeable. One will be spliced from the from the switch and blue trailer brake wire that is running from the trailer connector to the trailer brakes. The other wire will be spliced to the blue brake wire coming...

- Troubleshooting Trailer Electric Brakes and Breakaway Kit InstallationIf you just put new brake assemblies on your dump trailer, the brake magnets have two wires and it doesn't matter which one gets the brake controller output voltage and which one is grounded to your trailer. You do want to make sure the one grounded to your trailer has a bare metal to metal connection free of rust, corrosion, or debris. If you have also added a breakaway system like the Replacement Tekonsha Trailer Breakaway Switch # 420000 you asked from, then you will want to install...

- Should Breakaway Switch Activate Brake Magnets When Pin Is PulledYes, the brake magnets should engage when pulling a properly wired breakaway switch pin. If the brakes aren't locking up on your trailer when pulling the pin then I recommend making sure the power source (battery) for the switch is fully charged and that everything is properly connected. When testing the switch I don't recommend having the trailer hooked up to the tow vehicle just so you can avoid any potential damage to the brake controller or wiring on the vehicle. I have attached a...

- Replacement Breakaway Switch for Trailer Breakaway SystemYes the Curt Push-To-Test Trailer Breakaway Kit # C52042 would work as a replacement breakaway switch replacement but it comes with probably more components than you'd need if you only need the switch. Instead you could use the part # 420000 which is a universal switch that can basically fit any system. This would wire in exactly like your current switch. Either wire can be used as the power or ground.
view full answer... - Replacement Breakaway Switch, Cable and Pin For Tap By Hoppy SwitchI'm going to have to recommend replacing the entire breakaway switch as I cannot locate any replacement parts for your Tap by Hoppy switch. I recommend the Tekonsha Trailer Breakaway Switch # 420000 for a replacement. The wiring is long enough to run to the factory connectors so you do not have to worry about splicing wires where they are going to be exposed to the elements. It also connects with a single screw and uses a 49" long cable and pin.

- Wiring an Up/Down Switch to Hydraulic Pump on a Dump TrailerIt sounds like you have a switch that has 3 positions, up, down, and off, similar to # PK34312. For each position that requires power there will be an input from the 12 volt power source and an output from the switch to the device it runs. You will run power in from the 12 volt source to the switch. There is likely a single input from the 12 volt power source. Then one output for up and one for down that will attach to the hydraulic pumps wiring accordingly. There is also likely a terminal...
view full answer... - Trailer Break Away Switch is Draining Trailer BatteryThere is always going to be power going to the breakaway switch but that power will not go anywhere unless the pin is pulled. And if the pin is pulled your brakes would lock up. There could be something else that is draining the battery. Check all the wiring to the battery, brakes, and break away system. You will be looking for loose or broken wiring, corrosion, and loose connections. Clean off dirt and corrosion on the wiring/connectors. You should also know that the 12 volt circuit from...
view full answer... - Replacing Breakaway Switch On a Trailer with ESCO Breakaway SystemYou likely can use any replacement switch since all they do is complete a circuit when the pin is pulled out. One wire on the switch should be connected to the positive battery terminal on the trailer. The other will tee into the wiring leading from the trailer connector to the brake magnets like in the diagram I have included. Just follow the wires on the old switch to where they are connected and remove them. I have also included a link to the right that should help.

- Can the Pin On a Tekonsha Breakaway Switch Be Removed To Replace Steel WireYes, the pin can be pulled off and you can then replace the wire. Make sure that everything is disconnected so you do not accidentally set the breakaway kit off.
view full answer... - Trailer Breakaway Switch Compatible With 12-Volt RV BatteryYes, the Trailer Breakaway Switch # 420000 can be wired to the 12 volt RV battery on your trailer as long as the battery has a charge line to maintain its power while you are towing. I prefer to use the Fastway Zip Trailer Breakaway Switch with Coiled Cable in 4' # FA80-00-2040 or 6' # FA80-00-2060 since there is less chance of the coiled cable becoming damaged. I have included the wiring diagram from Fastway that shows how the breakaway switch is wired to your RV battery.

- Are There DOT Regulations on the Pull Pin Lanyard of a Breakaway SystemThat we or Tekonsha are aware of there aren't any restrictions on the cable used on breakaway system. Typically in towing situations the restrictions aren't that specific. They will say you need a breakaway system that functions, but they won't get down into the materials used of the system in question. For more information on breakaway systems check out the link I attached.
view full answer... - Identifying a Trailer Breakaway Switch with ESCO Printed on the SwitchESCO actually stands for Elkhart Supply Corporation, that is the brand of your breakaway switch. Most likely it is part number LBS48-16. If you are looking for a replacement switch the Hopkins Replacement Break-Away Switch # HM20014 should work well for you. I attached a couple FAQ articles on breakaway switches for you to check out as well.
view full answer... - Troubleshooting Brake Controller that Only Works with Override LeverSounds like your brake controller will apply your trailer brakes if you apply the manual override lever but not when you press the brake pedal. This is a fairly common problem and the solution is the red wire of the brake controller. Make sure it is connected to a circuit that only sees voltage when the brakes are applied and none when released. Most likely the connection is the issue and just reconnecting the circuit will cause the controller to work again.
view full answer... - How Much Force Is Required To Remove The Pin On a Trailer Breakaway Switch? The Trailer Breakaway Switch # 420000 should be somewhat difficult to pull out. It is designed to stay in place unless the trailer disconnects and is held firmly in place to not be pulled out due to vibrations and possible road debris when towing. If you give the cable a quick tug it should allow the pin to more easily be removed for testing. You will then be able to attach your Coiled Breakaway Cable # FA80-01-2140.
view full answer... - Solution for Needing Blue Ox Breakaway Switch Replacement for BX88181The Blue Ox breakaway switch BX88181 is no longer available but it was basically just a standard breakaway switch so you could use the part # 420000 in place of it very easily. It functions the exact same and would wire in the exact same way as well.
view full answer... - Can Replacement Breakaway Switch # 420000 Be Used with Any Breakaway SystemFor the most part, all breakaway situations work the same way. There are a few exceptions but they are not common. If your existing system used 2 wires like # 420000 then you can use it or any similar switch. I have included a link to all of the breakaway switches we carry.
view full answer... - Replacement Breakaway Switch Recommendation for UPG D2901 SolutionI wish we carried that but we do not. One solution we can provide is to replace the entire switch with part # 420000. This will be the easiest solution and will work well as the switches are universal.
view full answer... - Are Trailer Brake Assembly Magnets Positive and Negative WiresOn trailer brake magnets like what's on the brake assembly # 23-106 the magnets are not polarity sensitive which means either wire can be used as the power or ground as long as the other is the opposite. This is why the wires of the assemblies are typically the same color like on the # 23-106 they are both white.
view full answer... - How Does Replacement Breakaway Switch Wire into CircuitI don't have a specific way to recommend wiring the part # 420000 to a dump trailer but essentially this switch wires into a circuit by just cutting the wire and splicing it between the two wire ends. Whenever the plug of the switch is inserted the circuit is dead and then when the pin is removed the circuit is active. I attached an install video for you to check out as well.

- Availability of a Coiled Breakaway Cable To Keep the Cable From Getting Caught in Bed of TruckWe have the Roadmaster Coiled Breakaway Cable, # RM-8603, that could be used in the bed of your truck to keep the cable from getting caught on items in the bed when towing your fifth-wheel or gooseneck trailer. This cable can extend up to 8 feet in length to allow cornering and sharp turns with the trailer.
view full answer... - Troubleshooting Wiring Issue of Trailer Breakaway SystemMost likely the problem is not insufficient amperage if the fully charged breakaway battery won't apply the brakes. You can test this however by running a jumper wire from a car battery to see if the much higher amperage of that battery does the job. I would be very surprised if the problem wasn't the wiring. Electric stuff can be frustrating to diagnose, but if you go over all of the connections and compare the setup to the diagram I attached you should be able to find the problem.

- BrakeBuddy Breakaway Switch and Battery Charger Kit for Flat Towed VehicleBreakaway cables are actually pretty universal so you should be able to use the Tekonsha Trailer Breakaway Switch # 420000 that you referenced for your BrakeBuddy. The BrakeBuddy does utilize banana clips to connect to the BrakeBuddy itself so you will need to get some of those from an electrical supply store. To charge the battery in your vehicle use the Battery Charge Line Kit for Towed Vehicles # RM-156-25. I typically recommend this with the Flexo-Coil Wiring Kit # RM-15267 for a towed...
view full answer... - Troubleshooting Trailer Breakaway Switch and Grounding Wire On 14-Foot EZ-Dump TrailerAfter speaking to my contact in the electronics department at Cequent, I have discovered what could be the source of the problem. If the ground is disconnected, the breakaway battery ground is disconnected, and if the trailer is not attached to a tow vehicle, the 12-volt current you are detecting in your trailer frame is the current that should be going to your ground. Try the test again with these issues resolved and the problem should take care of itself. If you continue to have the...
view full answer... - Breakaway Battery Causes Trailer Breaker to Pop When Connected TroubleshootingSounds like you have at least a few wiring problems going on with your setup. Instead of trying to troubleshoot each issue you have I think it would be smart for you to inspect all of the trailer wiring you have starting with the 12 volt circuit from your tow vehicle to the battery and breakaway system to see if you can find any shorts or exposed wire and fix as necessary. I attached a diagram and an FAQ on breakaway systems for you to check out. I also attached an FAQ on trailer wiring...
