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

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

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

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

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 kit has all the components you need to complete the breakaway system for your trailer with electric brakes. I conjunction with a junction box (Item 38656 or similar), I rewired the front of my trailer with a very neat, clean, and serviceable system. 25967

this type of installation is not only easy but will help when my clients get pulled over for any reason by a traffic officer who wants to check his trailer. They can at a glance see the battery is good. We have installed 7 of these so far.15390

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

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
