Video Transcript for Hopkins LED Breakaway Switch Installation

Today on this enclosed trailer, we're going to install part number HM20060, from Hopkins. This is their LED breakaway switch. Our first step is to go ahead and remove the original breakaway switch. We'll follow the wires back to the junction box underneath the trailer, then we'll go ahead and disconnect the wires. We'll pull them loose, and we'll also disconnect the wires going to the breakaway kit battery. These have two terminals, so we'll just remove them from the battery.

We'll take our blue and white wires and run them to the junction box and make our connection. Our blue wire from the breakaway switch will hook up to the brake lead in our junction box. In this case, we will connect it to the black wire. We'll strip it back and splice it in. We'll repeat this with the white wire, which we'll splice with the other white wires for ground.

Once those connections are made, we'll put the cover of our junction box back in place. Now we'll go ahead and take our black wire from the switch, and we'll run it up through our breakaway battery. Now we'll have to add a terminal to it so we can attach it to the battery. We'll also get an extra piece of white wire, and we'll use that for our ground. We're going to take the negative side of the battery and we're going to ground it to the frame.

We'll cut our extra wire the length we need. We'll strip both ends back. On one end we'll put a ring terminal, and the other a battery terminal. These connectors are not included with the kit. Now we'll mount our breakaway switch.

Now we'll go ahead and test it. We'll pull the pin, and you can see how the LED lights up when there's power being applied to the brakes. And with that, that will finish it for our test fit of part number HM20060, from Hopkins, on this enclosed trailer.

It looked fine but I sold the unit and gave the item to buyer. 248662

Fast shipping. Exactly what I needed. 453231

Already hooked up and in use. Thanks 437551

Exactly as described, easy to install. 230035

This switch was really easy to install and works perfectly. I love the indicator light because it lets me know it is working. It flashes every few seconds when plugged into a vehicle or shows a solid light when the switched is pulled. I was actually inspected at a border checkpoint recently and I was able to show the highway patrol officer that the switch was working due to the light. He told me he wished everyone had one like this. Everything I have purchased from etrailer has come quickly and worked exactly as described. You can tell this company and their employees take great pride in what they do. I am a customer for life. 202003

Exactly what we needed to finish our trailer up!!! 184261

Great customer service and fast shipping. The break away switch was easy to install. Tested it and works great. I like the LED light that show power going to the brakes from the break away switch. 167781

As advertised, quick shipping 146039

Easy install with labelled wires that are long enough to route where you want them. The LED that shows when the brakes are engaged is a great feature to test the battery. The pin cable is about 3 ft long which is plenty for most trailers. Everything works as it should. 117471

Changing out from a two wire switch. Would be nice to have wired instructions with the switch order. For right now, I'm just using the two wires for the "switch" and not using LED. 64009

- HM20060

fast response and shipping. 57692

- HM20060

Installs just like the original, except that the LED requires a ground wire as well as hot and brake wires. The LED is a nice feature - pulling the pin turns it on to verify that the battery is charged, and pushing the pin back into place turns it off to verify that the brakes don't stay on. The only thing I can nitpick is that I wish it had 12 gauge wires instead of 14 gauge, but 14 is perfectly acceptable for most brakes. 49040

great switch! 33393

Great design with LED to indicate charge of your auxiliary emergency brake battery. 22955


Ask the Experts about this Hopkins Accessories and Parts

Do you have a question about this Accessories and Part?

  • Where do the Wires of a Trailer Break Away System Install Onto
  • In the diagram that you referenced, that I also attached here, the brake output circuit is a separate circuit that carries power to the trailer brakes totally separate from the brake light circuits. Also, the 12 volt power source is a separate circuit from the running lights circuit. If you have a 7-way trailer connector you will have these circuits. To see where the pins are on typical 7-way check out the picture I attached. I also attached an FAQ article on trailer wiring for...

  • Does a Breakaway System Need To Have Its Own Battery
  • The breakaway system actually must be attached to its own separate battery by law in most states. Therefore, I cannot recommend that you use a seperate, auxiliary battery on the trailer or the vehicle for that matter for the breakaway switch. The most cost effective breakaway system we have for you is the Curt Soft Trac II Trailer Breakaway Kit part # C52026. I have attached a photo for you to show how it will need to be wired.

  • Troubleshooting Trailer Brake Output Circuit Melting Wire After Bearing Change
  • There was definitely a short somewhere on your brake output circuit. A bad ground would just cause the circuit to not function. I attached a help article that covers everything on testing brake magnets. It is possible that when you were replacing the bearings you damaged the brake output circuit and that is why it is shorting out.

  • Can a Breakaway Switch be Wired Directly to the Trailer Battery Rather Than the Breakaway Battery
  • All breakaway switches are designed to be wired to the positive terminal of a 12 volt battery and to the vehicles electric brake circuit. The switch can be wired to your trailer battery if you did not want to purchase a separate breakaway battery. The Hopkins LED Breakaway Switch, # HM20060, has three wires because it has an LED light in the switch. The ground is for the LED light, not the brake switch. When the pin is pulled, power would still be fed to the electric brake circuit....

  • Does Brake Controller Voltage Plus Breakaway Battery Voltage Double to 24 Volts
  • Two sources of 12 volts applied to the same circuit would not double the voltage to 24 volts. Essentially this wires the circuits parallel to each other so the only thing changed is increased amp hours due to more amps applied. If you were to wire to 12 volt circuits in series instead then the voltage would double to 24 which would cause problems. I attached a picture that shows the difference between series and parallel wiring.

  • Troubleshooting Trailer Break Away System
  • The break away system on a trailer would typically have its own battery, like that shown with part # 20400. The reason that pulling your break away switch does not actuate your brakes is that it is not wired correctly. The break away switch should be wired so that it is a normally open circuit that closes when the pin is pulled. When the pin is pulled, the circuit closes, allowing voltage to travel to the trailer brakes. One leg of the switch should be wired to the positive terminal...

  • Do You Have a Replacement Pin and Lanyard for a Trailer Breakaway Switch
  • If you have the Tekonsha trailer breakaway kit you will need the Replacement Tekonsha Trailer breakaway Switch, part number 420000, to replace your lost or broken cable and pin. If you have a Hopkins Breakaway system then you can order the Replacement Cable and Pin for Hopkins Breakaway Switches, part number HM20051 which works on the HM20059 and HM20060 breakaway switches.

  • Installation of the Hopkins LED Breakaway Switch # HM20060
  • The Hopkins LED Breakaway Switch # HM20060 has a red LED light to indicate that the cable has been pulled. My technical contact at Hopkins suggested that you may have the black and blue wires reversed; this would cause the light to stay on. Please refer to the linked installation video for illustration of how to wire this switch.

  • Why Would My Hopkins Break Away Switch Blink
  • I contacted Hopkins and the only reason that the LED light on the Hopkins break away switch part # HM20060 would blink is because of a partial connection somewhere on the setup. The light should not illuminate if you have a proper connection at the pin and wiring. If you wiggle the pin and the light blinks then the pin may not be properly seated. You want to push the pin in and make sure it is completely inside the box. If the pin is properly seated, you want to check the wiring...

  • Breakaway Switch Pin is Stuck in the Switch
  • I think you mean breakaway system. A brake controller would be in the cab of the vehicle and not on the trailer. You might need a new switch if you can't get the pin out. It would not be a bad idea to replace it anyway. They are not expensive and you will have the peace of mind of having a new switch. A switch, such as # HM20010, # 2005-P, or # HM20060, basically just completes a circuit once the pin is pulled allowing power to go from the breakaway battery to the trailer brakes....

  • LED Light On Hopkins Pull to Test Breakaway Switch Staying Illuminated When Pin Is Installed
  • The red LED light on the Hopkins LED Breakaway Switch # HM20060 indicates that the cable has been pulled. My contact at Hopkins said you may have the black and blue wires reversed. This would cause the LED light to stay illuminated. I have attached a link to a video for this breakaway switch that shows how it's wired when installing.

  • Replacing Breakaway System Switch on Lacrosse Travel Trailer
  • All the breakaway switches we offer serve the same function and are pretty much interchangeable as long as the switch on your trailer is normally closed. The circuit is normally closed until the switch pin is pulled, which closes the circuit and allows the voltage from the battery to reach the trailer brakes. Just because the system you currently have uses a switch from Bargmann, doesn't mean your replacement needs to be of that brand too. The Hopkins replacement breakaway switch, part...

  • Can the Hopkins LED Breakaway Switch # HM20060 be Used with a Trailer Battery
  • Yes, you can use the Hopkins LED Breakaway Switch, # HM20060, with your existing trailer battery as long as the battery is a 12 volt and can power the trailer brakes at or above DOT specifications. On the switch, the black wire will be connected to the positive trailer battery terminal, the white wire will be grounded to the trailer frame or to the negative battery terminal. The blue wire will attach to the electric brake wiring. In some states, a break away system is required by law...

  • What Might Cause Trailer Battery to Die When Connected to Tow Vehicle
  • What all is connected to your trailer battery? You'll need to go through the list of all connections made to your trailer's battery so that you can determine what all could be drawing amperage and then make sure all of those accessories are turned off when you are towing. The 12 volt accessory pin of your 7-way can put a maintenance charge on your battery as well if needed. This is the pin in the 1:00 position on the vehicle 7-way. You'd want to run 10 gauge wire like part # 10-1-1...

  • Recommendation for a Trailer Break Away Kit
  • To add a break away system to your trailer, you will need a switch like the Hopkins LED Breakaway Switch, # HM20060, and a battery that meets DOT specifications for a break away system. Or you can by a whole kit like the Engager Trailer BreakAway Kit with Charger and Tester, # 20099. With this kit, you get the switch, battery, case, LED tester, and charger. I have included a link to the installation details below. I have also included a link to our FAQ article on break away systems.
