Highly recommend. Own a 99 F250 7.3 diesel. Easy install. No issues. We have not had to use the break away aspect thankfully but have no worries that it would work well if the need ever arose. We replaced our breakaway due to hitch failure on the truck. The bolts had loosened over time and one was missing. The whole hitch system fell to the ground under a full load at a red light. After my husband hyperventilated we were able to get traffic to stop and go 25 feet to safety. We are very familiar with the need for a break away and highly recommend. What happened to us is rare and our mechanics are so paranoid now that inspection of hitch systems no matter the truck are fully inspected so far they have found and prevented five potential disasters. All of our replacement items came from etrailer....hitch...ball..tongue and breakaway. We upgraded the weight limit of the hitch matching the weight to ball and tongue. We are currently saving to replace our jack to a more heavy duty easy use high weight bearing. When we do we will head to etrailer for our new jack. Highly recommend this company and all of the associates we have talked to have been great. Btw upgrading the hitch and tongue to handle weight has helped our hauling ability, ride and fuel. mileage. Have a wonderful day 850804

Ask the Experts about this Hopkins Trailer Breakaway Kit

  • Recommended Trailer Breakaway Battery Braking System with Integrated Charger
    The Hopkins Engager Push-To-Test Trailer Breakaway Kit w/ Built-In Charger - Side Load - 7" Wire # 20099 is the most popular option by far followed by the top loading version # 20400. This is my recommendation for the best option. Many trailer manufacturers utilize this breakaway kit because of its function and ease of use. I've attached a photo to assist with the installation.

  • What is the Difference in Hopkins Engager Breakaway Systems 20099 and 20400
    Hopkins Engager breakaway systems # 20099 and # 20400 function the same way and have the same features. The main difference is in how they mount. Engager # 20099 is meant to be mounted on top of the frame with the LED indicator and test button facing up. Engager # 20400 was meant to be mounted to the side of the trailer frame so that its LED indicator and test button are also facing up. You will want to make sure the battery in the system you use is protected. That is why breakaway systems...

  • Wiring Directions for Hopkins Engager Push-to-Test Trailer Breakaway Kit
    The wiring directions for the Hopkins Engager Push-To-Test Trailer Breakaway Kit # 20099 referenced in your question are as follows: 1. Splice one blue wire of the Break-Away Switch to the electric brake wire coming from the trailer side connector. 2. Connect other blue wire of Break-Away Switch to the blue wire (labeled Brake) from the Break-Away box (Note: Blue wires are interchangeable on the Break-Away Switch.) 3.

  • Troubleshooting Trailer Breakaway Wire That Didnt Activate Trailer Brakes
    It sounds like you had not just a breakaway pin pulled but a wiring issue. If not, the breakaway wasn't connected to your trailer correctly as the brakes should be activated but the trailer tail lights wouldn't be. To me it sounds like the pin is connected to the brake lights and not the brake magnets. I've attached an article to help with the connections and have also attached a couple videos and a diagram. It sounds like you may need the Hopkins Replacement Break-Away Switch, 7"...

  • Easy Solution for Lost Pin for Trailer Breakaway System
    The TAP Engager brakeaway kit you have on your trailer is a standard style of breakaway very similar to the Hopkins Engager part # 20099. For a replacement pin setup that would work well we have the # HM20010 which gives you a new switch, pin and cable. This is the easiest way to replace a breakaway pin is replacing the switch and pin all together as the switches themselves are all universal but matching the pins can be a bit harder. For just the pin of this system we have the # HM20051...

  • Yellow Charge Light On Hopkins Engager Stays On with Trailer Disconnected
    In regards to the Hopkins Engager Push-To-Test Trailer Breakaway Kit part # 20099, the first issue that you described of the yellow charge light being on even while disconnected from the tow vehicle could either be a short in the circuit board or if the trailer has an auxiliary battery this is then feeding the breakaway battery and in which case you would need to install a diode part # RM-690 to prevent this. The issue with the yellow charge light illuminating when the battery test button...

  • When Does Trailer Breakaway Battery Receive Incoming Power
    The Hopkins Engager Push-To-Test Trailer Breakaway Kit # 20099 (formerly BA10-150) will draw power from the tow vehicle while it is connected. This 12V power draw maintains the 5-amp-hour breakaway battery. When the trailer is not connected to the vehicle the breakaway battery will receive no charging power. The breakaway switch will not draw any power from the trailer breakaway battery when the trailer is disconnected unless the switch is pulled.

  • Installing The Brake Rite EHB System With The Hopkins Break-Away Battery Kit
    For the Engager Trailer BreakAway Kit with Charger and Tester # 20099 from the break-away battery, the white goes to ground, the black goes to the violet wire on yourTitan BrakeRite EHB Electric-Hydraulic Actuator for Disc Brakes # T4813100 for the positive 12V battery charge, and the blue wire goes to the blue wire on the breakaway pin. On the other side of the pin, the black wire will connect to the brown wire of your Brake Rite unit.

  • Does the Charging Light On The Hopkins Engager Breakaway System Stay on When Trailer is Pluged In?
    Yes. With the Hopkins Engager Trailer Breakaway System # 20099 , when the trailer is connected to the tow vehicle through the 7 way connector the yellow charging light will always be lit up.

  • Should Trailer Brakes Hum While the Breakaway Pin Is Pulled
    Yes, when the pin on a breakaway system like the Hopkins Engager Push-To-Test Trailer Breakaway Kit part # 20099 is pulled that then sends full 12 volt power to the trailer brakes. When power is sent to an electric braking assembly you may very well hear sort of a humming noise and this is not uncommon at all nor it is an indication that a problem is present.

  • Push to Test Trailer Breakaway System Shows Charging/Depleted Battery when Connected to Tow Vehicle
    Push to test type of breakaway systems seem to give false readings some times when they are connected to the tow vehicle. There could be a short somewhere in the system that, when connected to the tow vehicle, is causing some slight power draw. The most likely culprit is a dirty or corroded trailer connector or wiring. Make sure that both the vehicle side and trailer side connectors are clean and free of corrosion inside where the wires attach and outside on the pins. You can also inspect...

  • What Gauge Wire is Used In Engager Trailer BreakAway Kit with Charger and Tester
    Per my contact at Hopkins, the wires used with the Engager Trailer BreakAway Kit with Charger and Tester, part # 20099 are all 16-ga wire except the battery wire which is 14-gauge. The wire form the breakaway switch to the box is 16-gauge.

  • What is the Difference Between the Hopkins Engager Breakaway Kit # 20099 and # HM20119
    The difference is the length of the lead wire. Both part # 20099 and (discontinued) part # HM20119 use the same Engager Push-To-Test Trailer Breakaway Kit w/ Built-In Charger but the part 20099 only has a 7" long lead wire while part 20119 has a 44" long lead wire.

  • How to Wire Trailer Breakaway Switch to Trailer
    A trailer breakaway kit like # 20099 needs to be connected to the vehicle's 12V auxiliary power circuit so that it receives a maintenance charge at all times you are driving, not just when the lights are on. The wiring and mounting requirements, as well as the procedure for testing your breakaway system, are covered in the two articles I linked for you. Your best bet is to re-wire the trailer to match your Suburban's 7-way setup. This takes only a junction box like # 277-000141 and...

  • Troubleshooting Hopkins Engager Break Away Kit That Wont Recharge Battery
    The Engager Trailer BreakAway Kit with Charger and Tester # 20099 will charge if the black wire from the breakaway box is receiving 12 volts from the 7-way on your tow vehicle. You will want to use a circuit tester like part # PTW2993 to test this wire for 12 volts when the vehicle is connected and running. If there is no voltage there then you will need to trace this wire back to where it connects to your vehicle wiring and make sure it is connected securely to the 12 volt circuit...

  • Comparing Hopkins Engager Breakaway Kits 20400 and 20099
    Pretty much the only difference between the Engager breakaway systems # 20099 and # 20400 are the designs of the battery boxes. Both function the same and have the same features. Engager # 20400 is meant to be mounted to the side of the trailer frame whereas # 20099 is designed more from the top of a frame. But ultimately you could install them anywhere there is space so I wouldn't say one is better than the other for you trailer.

  • Can a Diode be Used to Prevent Back Feeding from a Trailer Breakaway Battery to a Brake Controller
    You could install parking light diode # RM-690 to allow power to only flow in one direction and that would prevent accidental back feeding. The diode is rated for 85 amps on a 12 volt system.

  • Do Trailer Brakes Lock Up When Brakeaway Kit is Activated
    When the Hopkins Engager Push-To-Test Trailer Breakaway Kit w/ Built-In Charger # 20099 gets activated, your trailer brakes will immediately lock up. It sends the full 12 volts to your brakes to stop the trailer as soon as possible. This is assuming, of course, that the breakaway battery is fully charged, which should not be an issue with this kit due to its built-in battery charger. I have added a link to a video review of this kit for you to take a look at as well as a couple help...

  • Is a Breakaway Kit Required on an Old Trailer
    In order to determine if a breakaway system is required on your trailer you will need to contact your local DMV. This will vary from state to state. However, it is a good ideal to add a breakaway system regardless of your state's regulations as they will help to protect others on the road and your trailer in the event of an accident. Breakaway systems are relatively inexpensive and can easily be installed with minimal effort. I recommend the Hopkins Engager Push-To-Test Trailer Breakaway...

  • Trailer Battery Not Charging While Towing with 2016 Ford F-150
    The 12 volt trailer battery charge circuit is not active on certain models when in park or during gear shifting so if you were trying to test this via the pins on the trailer connector this would be why it is not active. Also, the 12 volt trailer battery charge circuit must first be activated via the in-dash screen. If you need help with doing this you can refer to the owner's manual. If the 12 volt trailer battery charge circuit is still not active after addressing the above then you...

    Are you getting power on the pin in the 5 O'clock position on the 7-way at the rear of your 2016 Ram 3500? This is the brake output circuit. That's the first thing you need to check to find if the problem is with the truck or the trailer. If there's not power on the brake circuit the problem is likely a blown fuse. You said you already replaced the 7-way. Was this on the truck or trailer? Whichever it was inspect the other one for corrosion and clean it if need be. If the truck...

  • Troubleshooting Flashing Yellow Light on Hopkins Engager Breakaway Kit
    I spoke with my contact at Hopkins and he said that the yellow light on the Engager Breakaway Kit # 20099 should not be flashing. It is designed to stay constantly lit when hooked up to the tow vehicle and charging. He said if the light is flashing on your it then it's possible that it's getting pulses of 12V power for some reason instead of a constant input when hooked up. I recommend first testing the 12V wire coming from the back of the trailer's 7-Way when it's hooked up with a...

  • How to Wire Up a Breakaway Battery and an Auxiliary Battery on a Trailer without Backfeeding
    It sounds like the tilt battery is backfeeding onto the breakaway battery charge line so as long as the ground is connecting it is taking a charge from the tilt battery and that is why your charge light is staying on. I have a solution for you, you will need a single function diode part # RM-690. You will need to wire it in between the breakaway battery and the tilt battery and it will stop the backfeeding from your tilt battery to the rest of the 12 volt circuit wiring of your trailer.

  • How to Prolong Life of Breakaway Battery During Winter Storage
    You could potentially store the Hopkins Engager Breakaway Kit # 20099 battery inside but that would only protect it from the colder temperatures, so you would still need a solution to re-charge it, and there really isn't an easy way to remove it without having to cut some wires or unscrewing it from the trailer frame. A better and simpler solution is to use a battery charger/maintainer, like the NOCO Genius UltraSafe Battery Charger and Maintainer # 329-GENIUS1. It will work great to...

  • Can Breakaway Battery be Overcharged By 12V Circuit From Tow Vehicle 7-Way
    You can definitely use the 12V power from the tow vehicle's 7-Way connector to maintain the charge of your trailer breakaway battery. This circuit from the 7-Way carries enough power to maintain a battery but not enough to actually charge up a depleted one. With this in mind you do not need to worry about overcharging the battery as it will really only get a trickle-type charge during travel.

  • Guide to Use to Test Trailer Brake Magnets
    Sounds like your brakes aren't working when you use the breakaway kit or when your tow vehicle applies the brakes which leads me to believe the problem isn't the breakaway and it's most likely electrical.

  • Can Trailer Breakaway Switch be Used as Parking Brake
    I do not recommend using a breakaway switch like the Hopkins Engager # 20099 that you referenced as a parking brake to hold the trailer in place. When pulling the pin out of the switch full 12V power will be sent to the trailer brakes and it won't release them until the pin is re-inserted or the battery dies. Locking the brakes up like this for longer periods of time may actually cause damage to the assemblies themselves. A better option to keep your trailer in place when it's parked...
