Video Transcript for Hopkins Trailer Breakaway Kit 20099 Review

Today were going to review part number 20099. This is the Hopkins Engager Trailer Breakaway Kit with the charger and tester. This breakaway system kit is designed to bring trailers safely to a stop by activating its electric trailer brakes on the trailer should that trailer be disconnected while driving. This type of safety system is required in most states on trailers that are rated over 3,000 pounds. This kit does include a built in battery charger in this weather resistant battery box. On the side is a sealed 12-volt rechargeable 5 amp battery.

It does also include this breakaway switch. It has an LED tester, which is included in here. You will see if you push it itll show green for charged. Now if it shows red it would need to be recharged and if it shows yellow that means its charging. It does also include the mounting screws to mount this to the trailer and includes this cable with the pin on the end.

The pin is what would attach into the breakaway switch.Now this box can be mounted on a trailer jack or on the trailer frame. This will work with single axle and tandem axle trailers. This does have an automatic shut off. When fully charged this green indicator light will remain on even when the charge is full. Basically the way you would install this, you would use your three mounting screws and theres the three mounting locations.

This box has three wires coming out of it. The white would need to be attached to a good ground. The black would go to the vehicles battery, and then this blue wire would actually attach to the blue wire on this breakaway switch. Then this other black wire on the breakaway switch would attach to the electric brake wire coming from the trailer side connector. This would actually be mounted closer to the front of the trailer.Basically once thats all wired up what you need to do is insert your pin and push it all the way in and then run your steel cable here up to your tow vehicle and attach it.

What happens in the case of where your trailer might come disconnected it would pull that pin out. When that pin was released from this breakaway switch it would activate current from this battery box to the electric brakes on your trailer, which then would stop the trailer immediately.A few dimensions on this. This box is 5 and 5/8 inches wide. It is 5 and 1/8 inches tall and 4 and 1/8 inch deep. That should do it for the review on part number 20099, the Hopkins Engager Trailer Breakaway Kit with charger and tester.

Item came with NO installation instructions. Had to search, download and printout on my own. Item P/N was NOT listed on mfr's site but did find instructions under a different PN. No mounting hardware (screws) were provided. Item was successfully installed on Utility/Car Mover trailer and appears to work properly. Battery capacity is minimal (5VA) - will power a single axle brake (5 amps) for less than an hour. Tow vehicle battery charger (12v) circuit is mandatory. No provision for an external battery charger connection is provided. DO NOT TEST while electrically connected to tow vehicle - it will damage your Brake Controller. This is important because connecting the breakaway switch lanyard as recommended requires pulling the plug from the switch which back feeds 12v to the tow vehicle's brake controller. Must connect the lanyard BEFORE connecting the trailer electrical cable and vice-versa when disconnecting. Switch mounting plate is very thin and flimsy - easily bent when applying force necessary to reinsert breakaway plug. Must hold the housing while inserting. Do not install the battery housing or switch where subject to possible external physical impact forces or loads. They are both plastic and easily damaged. 447168

Excellent product! I got this for Christmas 2009. The kit comes complete with unit and easy-to-follow instructions. I installed it last week (4/10) in about 30 minutes and it worked like a charm (minus a little brake wire issue that had nothing to do with the break-away switch). The charger works off the wiring harness, for those of us who don't have PUP batteries, and a push of the test button shows charge status: Fully Charged, Recharge, or Charging. No guess work involved. The only complaint, albeit a very minor one, was that it only came with three (3) self-taping screws; the main housing unit took 3 on my unit (sometimes two depending on the width of the mount frame) and the switch housing requires one. Additional cost: $0.13 at the local hardware store. Highly recommended!!! 2931

Seems adequate Just installed this on our 09 Fleetwood Taos which did not come with a battery. Installation not too difficult, but battery box is too tall to get all three screws on the tongue frame, so just used two and seems sturdy enough. On the camper, I had two wires (a black and a white) coming out of the frame near the 7-wire cable, these had a connector clip at the end. The camper had a breakaway switch that was spliced to these 2 wires. So I followed the wiring diagram and connected the new switch and battery to these wires, instead of splicing into the 7-wire cable. Will do a test, to see if this was right. Wires from battery box are not long enough to mount the battery to frame under the front of the camper and reach the switch near front of the tongue. 3109

I will just make this short, overall it’s a good product, straight forward, easy to install. I wanted something that would keep my break away battery charged. With a built in battery charger and indicator this fit the bill. I however find that it is very susceptible to rain intrusion because there is no seal between the lid and battery box. The charge indicator light will come on and kill your battery, so because I needed this thing on the road, I dried it out and sealed it up with silicone. I did contact E-trailer and the where very helpful with my issue. 172058

Got my breakaway kit in 2 days. It took 2 Hrs to install...works GREAT>>>>>it replaced the 7 year old dead batt and kit on trailer. My trailer don't have a "power" wire for the charger..if your trailer does cut 30 min's off install time. As a professional truck driver SAFETY FIRST on my trailer...and the Test button lets me know it is good to go. 13925

Pros: Sturdy enclosure, test button, break-away switch comes with 2 pins (handy when somebody drives off with your break-away cable) Cons: Conductors battery enclosure without any jacket/loom, conductors not protected from chaffing where they exit the plastic battery enclosure, conductors leaving battery box are short (18"), no strain relief of conductors exiting battery box (only thing holding them in the box is the solder connection to the charger pcb). Self-tapping screws don't appear corrosion resistant. Not sure if there is a higher quality product available. While this will get the job done, I wasn't impressed. 11407

The Hopkins battery box and break away switch showed up in record time with a fully charged battery. I also purchased a 7 blade plug / 24' 7 wire / 2 termination boxes. My old horse trailer has 18 various lights, some always hot, some on toggle, some running lights, stop and turn signals. I used 2 term boxes, front and rear, to help me in chasing future shorts but couldn't find a termination box at my local store. Etrailer had everything I needed to complete my project. I'm looking forward to purchasing trailer tires/rims from this company. The prices can't be beat, assuming free shipping. 489356

Bought this kit last year to replace the original unit on my car hauler that was simply a battery in a box. This unit wired in with very little effort. I especially like the indicator lights that show you the status of the battery when plugged into the truck and the test button is a great feature when it's just sitting. So far this unit is great and I hope that I never have to find out if it actually works...cause that would mean I lost the trailer! But I have a feeling if that ever occurs, I'm confident this unit will fiction as it should and bring the trailer to a stop! Highly recommend. 305880

As for Hopkins emergency breakaway, white to clean ground run through white on epichord box. Make sure the white from epicord box is grounded by seperate lead or the emergency breakaway box is not ground by simple virtue of connecting to white epicord box terminal. Run blue emergency breakaway box wire to black lead from breakaway pull pin switch. Then blue switch lead directly to blue terminal on epichord box which is also connected to trailer blue brake lead. The black emergency breakaway box lead goes to black terminal on epicord box already connected to positive battery lead. 423172

Bought this to replace the box that was torn up by thieves who stole my trailer. Previous box did not have the battery charge tester, so this is a nice upgrade. Very durable construction. Easy installation and instructions, which included a good drawing. Super fast shipping, which prompted me to order more items. Have dealt with etrailer.com in the past, and I am glad that I returned. 65762

I normally don't write reviews, but in this case I feel that I should. I worked with Donna who was most helpful. She was careful to ensure that I ordered the right parts. She was patient with me as I had a bunch of questions and did not order right away. I received the parts rather quickly and they were completely easy to install. SHIPPING WAS FREE FOR MY ORDER. I would most defiantly do business with etrailer again. Not to mention the prices are very reasonable. Send etrailer your business. 471984

Looks good came fully charged and I don't know how long it works to hold the brakes for because I haven't had a failure yet. Just connect the blue from the switch to the brake wire and the black to the blue on the box and you should be good to go. I don't tow the trailer enough to feel good about letting it sit its mainly for heavy equipment so I'm going to wire a battery tender to it to keep this one from going bad which I would highly recommend if your not towing or charging it biweekly 376291

The product arrived broken. I realize it's not your fault. Customer service was not very accommodating. I needed to used the trailer so I had to purchase another breakaway kit from a local store. Now I'm stuck with another kit that I don't need. I asked the girl if she could ship it overnight so I could get my trailer ready, she said no. Go through my records , you see that I spend a fair amount of money with you. Not my fault the part came broken but you made me feel like it was 410510

Nice product, all the pieces were there, easy installation. The only (slight) negative is that the wires from the battery were not long enough to go back to the trailer junction box so some splicing was called for. Otherwise, as advertised. Great helpful video. As with all the videos (in my opinion), some explantations were glazed over - you need to watch it a couple of times and pay attention to the details and take notes. Installed on a T@G, 6’ wide. 500159

I got the product and didnt have time to put it on immediately. When I did get it out of the box a few days later. The case was cracked. I called etrailer and was put on hold for an extremely long time, so I found an email where they wanted me to write a review and replied to the guy who sent it to tell him about the issue. I have not heard back from anyone at etrailer. So, I am writing this review hoping that I will get someone to call me or email me. 417575

Arrived as scheduled. I was replacing stock unit so I only had to drill one hole and cut and splice wires. Very simple and easy installation. Product seems tough built and so nice now to check battery with the push of a button. 448164

I own several trailers with electric brakes on two axles with this kit. All have lasted for many years. Indicator light is very handy for an easy check especially if I don't use the trailer very often. Easy to wire in to an existing system. Most all new trucks come with a battery lead to the factory connector that keeps this battery charged. Just need to make sure to have a 6 or 7 pin plug to the trailer. 175816

Arrived within a couple of days, everything I thought it would be, took a hour to mount because I soldered and heat shrunk all connections. Everythng I've ever bought from etrailer has been quality parts. 55074

The easiest, most courteous, prompt people to do business with. I have already told anyone that would listen how accommodating etrailer is. I was pleased my shipping was free but couldn’t believe it when they emailed me and told me they upgraded my delivery with no additional charges. I had everything delivered in one box in 3 days and all parts were excactly correct and worked perfectly. 44638

I bought the Hopkins Breakaway kit to replace the one that came with the trailer which was exactly the same. The reason it needed replacement was because a heavy object was dropped on it and the case broke. This was no fault of the Breakaway by Hopkins. E Trailer is a great company to work with! UI have always had good products and fast shipping from E Trailer! Doug 346137

I have traded with etrailer a few time and service, ease to look up part in catalogue is a snap all the way to check out, and they let you know when you will receive purchased items, which is fast delivery. Communication is great. The prices of items are reasonable. Will continue to trade with etrailer. Keep up the good work folks. Jack 493362

As usual, etrailer has what you NEED at a fair price and ships like "Greased Lightning"! Sales people are on top of it and "GeterDone" like few others. This product hopefully will never be needed but it's a nice piece of required insurance on your towed vehicle. Installation is simple so no excuses y'all! 411714

This is the 2nd Engager BreakAway kit I have purchased. It is a well made item and has functioned well. I am only replacing it because the battery is getting old and I want to just replace the whole thing, which will take less than an hour. It arrived quickly from etrailer and in good condition. 368231

The verdict is still out on this unit, but it is what comes on all of the trailers we have purchased even the brand new one we just recieved. We do have some issues with the LED staying on after detaching the truck from the trailer, but hopefully a new unit will take care of it this time. 64716

I have used two of these already in the past, they work great. The only complaint is that after a few years in the sun the cover display becomes brittle and begins to leak. There is a version of this box that does not have a display that would probably rectify this issue 511129

Exactly what was described. The product was manufactured well and very easy to install. The information provided was easy to decipher and used the wiring harness diagram for easy install. I never go just color wire to color wire so wiring by function was easy. 83327

So far so good but the door or lid that seals the battery and the electronic charger does not fit tight and if mounted out in the open rain WILL get in it. This was not an expensive unit so I cant beat it up to much but keeping electronic dry is a basic. 201424

It works great. I test it and it puts the brakes on well. Even though the trailer sits disconnected for a few months at a time, the battery in the unit stays ready and it recharges as I use it. Makes me feel safer to have it and keeps me legal too. 484617

Only 4 Stars because if you cut the zip ties the lid will not stay closed on it own. Just have to put a new zip tie on, but installs easily and is very clean and works great to know if the truck is proving power or not. 385692

This wire is typically the number 4 black terminal in the 7-way connector, but you will need to test to determine if your plug is wired this way, as the auxiliary function can also be located on the center pin. Installing the black wire from the breakaway system to the 12 volt power source will allow the battery to charge when you have the trailer...

  • Can a Trailer Break Away Battery be Charged from the 7-Way Trailer Connector
  • If you have a break away kit that does not include a charger, you can provide a charge to the battery using the 12 volt circuit or auxiliary circuit from the vehicle 7-Way trailer connector. However, using the 7-Way can overcharge a break away battery. It would better to add a charger designed for a break away battery like # 20011.

If you look at the second picture on the product page you will see the color code information. The more detailed wiring instructions found in the manual for the kit 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...

  • Parts Needed to Add Electric Drum Brakes to a 2004 Viking Epic Model M2007
  • First and foremost, thank you for your service to our country. It is greatly appreciated. Ultimately you are correct that the most accurate way to determine the correct hub and drum assembly is to pull the hub and find the bearing and grease seal numbers or at least use a digital caliper # 301-17068 to measure the spindle where they sit. However, there are a few pieces of info that we can possibly piece together to make an educated guess as to what you have. We do have the Dexter...

  • Recommended Electric Over Hydraulic Trailer Brake Conversion for Dual 10K Axles
  • The Disc Brake Kit # K2R1058D13 by Kodiak is the brake set that you will need to use for your 10,000 lb Dexter Torsion axles. When it comes to hardware, like the brake line, I recommend going with the Kodiak Hydraulic Brake Line Kit # 24TA-BLKIT which will wear better than other traditional brands. These lines are very flexible so the line is easy to maneuver under the trailer. The only downfall is that you cannot cut the line due to how hard and risky it is to do yourself. All you have...

  • What are the Functions of the 3 Wires on Hopkins LED Breakaway Switch, # HM20059
  • You are correct, the Hopkins LED Breakaway Switch, # HM20059, does have 3 wires. The white wire is the ground wire and should be attached to the trailer frame. The blue wire on the switch will connect to the electric brake wire coming from the trailer side connector. The black wire goes to the break away battery. This part is just a switch, if you need a new system, I recommend Engager Trailer BreakAway Kit with Charger and Tester, # 20099. I have included a link to the installation details...

  • The Charge Light for Engager Trailer BreakAway Kit Stays On All the Time
  • The fact that it is staying on even when the trailer is not connected is strange. According to the installation details linked for reference, if the trailer is connected to the tow vehicle, the yellow charging light will always be on. The light stays on just to show that the unit is connected and has power. Since it is staying on, it has to be drawing power from the break away battery. The box is water resistant but not water proof. Moisture or corrosion build up in the box or wiring...

  • 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. Check...

  • Troubleshooting Hopkins Trailer Breakaway System Not Charging Battery
  • First you will want to check the wiring of the Hopking Breakaway # 20099. If the black wire from the breakaway box is not receiving 12 volts from the 7-way on your tow vehicle it will charge the battery. You will want to use a circuit tester like part # 3808 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...

  • How to Install a Brake Controller on a 2015 Jeep Wrangler Unlimited with Factory Tow Package
  • I have exactly what you will need for your 2015 Jeep Wrangler Unlimited to tow your Vintage Airstream with brakes. The first thing you will want is a 7-way trailer connector at the rear of the vehicle and for this I recommend the Hopkins Endurance Quick-Install 7-Way Trailer Connector part # HM42190 which is a direct plug and play option that will not require you to cut or splice any wires/circuits. The square plug on the end of this connector will plug into and replace the 4-way trailer...

  • How Long Will the Engager Trailer Breakaway Kit Battery Last Without a Charge
  • Battery life depends on so many factors that it is hard to quantify the life any given battery. I spoke with my contact at Hopkins and he stated that if the battery is stored outside he estimates a 3 to 6 month life span. If stored inside it will last a little longer and will most likely make it to 6 months. If the battery is not being charged via the 7-Way trailer connector regularly then it is recommended to charge the battery every 3 months using a battery charger like # CTEK56158. If...

  • Recommended Disc Brake Conversion on 10,000 lb AL-KO Axle
  • I reached out to Dexter Axle and spoke directly with their AL-KO/Hayes specialist. They said that there is not a conversion to disk brakes for their axle based on the axle itself. The issue is with the mount for the brake calipers. If you can fabricate mounts, I can give you everything else that will make your trailer compatible. I recommend the Redline Trailer Hub Assembly - 10,000 lbs Axles - 8 on 6-1/2, # 090814. These are compatible with your axle. This hub includes the races,...

  • Trailer Breakaway System Not Locking Trailer Brakes when Pin is Pulled
  • It sounds like something is miswired or there is a loose connection or poor ground somewhere. On the Engager the brake output wire from the trailer connector will go to a blue wire on the breakaway switch. You will just be tapping into this wire, the original wire still goes back to the trailer brakes. The other wire on the switch will connect to the blue wire from the box with the battery in it. The white wire on the box will ground to the ground wire from the wiring harness and/or...

  • Wiring a Trailer Breakaway Kit on a Bigfoot Travel Trailer
  • In order for a break away system to power electric trailer brakes, it will need a 12 volt power source (a battery mounted on the trailer). The battery has to provide a full 15 minutes of braking power to comply with DOT regulations. On the trailer connector there is a wire that goes back to the trailer brakes. This wire may be black or blue depending on the specific system. Attach one wire from the switch to the wire that goes to the trailer brakes. There should be another wire, usually...

Also, check to be sure the plastic breakaway switch pin is correctly inserted into the breakaway switch housing. Next, make sure that the ground wire from the breakaway kit, # 20401, is attached to the trailer frame and not wired into the trailer connector. My contact at Hopkins indicated that this could...

  • Where Should the Ground Wire be Attached for a Trailer Breakaway Battery
  • You will likely have several different grounds on any given trailer. The breakaway battery can ground by itself to the frame and to the trailer connector's ground if you want. But at the very least ground the battery to the frame. The brake magnets should be grounded independently near the magnets (axle or frame) for the best results. As long as the breakaway battery is grounded to the trailer frame and the magnets are properly grounded it will work should the trailer separate from...
