Video Transcript for Fastway Trailer Breakaway Kit FA80-00-2040 Review

Today we're going to be taking a look at part number FA80-00-2040. This is the Fastway Zip trailer breakaway switch with the coiled cable. The coiled cable's going to measure four feet long. Now, the breakaway switch is going to wire into your trailer's break system to provide a peace of mind. What it does is if the trailer becomes uncoupled or disconnected, the cord that's attached to the tow vehicle will pull the pin from the breakaway switch, which would then activate your trailer's brakes, bringing the trailer to an eventual stop. The coiled cable is a nice feature to have. You don't have to worry about that dragging on the ground.

Self retracts for easy storage. You don't have to worry about frayed ends, and you don't have to worry about looping the cable around the trailer tongue. It's going to stay nice and compact. Whatever slack is in the cable, the coil design's going to take up that slack again so you don't have to wrap it around your trailer tongue or secure it in any other way. The included carabiner on the end of the coiled cable makes for really easy connection to the tow vehicle. The cable's going to be a high-strength cable.

It's going to be made of woven steel, and it's going to have the UV protective coating that's going to booster ability, and it's also going to be scratch resistant. Now, right here on the bottom of the switch we're going to have the mounting bracket. That's going to feature a quarter-inch-diameter hole, that way you can easily get it secured to the trailer frame. Again, the coiled cable length is going to be about four feet long when fully stretched out. On this side right here, you're going to have the wiring. One wire's going to get connected to the 12-volt power source, the other wire's going to get connected to the brake controller output from the tow vehicle.

That wiring's going to measure about 47 inches long. The bracket itself, this is going to give us an overall length of about four and one-quarter of an inch, and the bracket's going to give us a width of about an inch and a half. That's going to do it for today's review of part number FA80-00-2040.

Working fine after a year post install.

etrailer products are outstanding quality and at a very fair price. Best of all their order tracking is by far the best of any retailer I have delt with. Keep up the outstanding service.


This solved the problem of the breakaway break cable getting caught and pulling away and signal the breaks to go on.
Easy to install. .. the length of the coiled cable is perfect to reach the bed of the truck where we hook it to a ring.

Been very pleased. This completely stopped the problem of the breakaway cord getting caught on things

My existing breakaway switch mount rusted and fell off. I picked the Fastway switch mainly because of the coiled cable. This should work better than the regular straight cable. I don't have to worry about it getting tangle up.


Easy install. Good quality. Fast servic e.


awesome product


I needed to replace my breakaway cable and battery on my horse trailer. Etrailer has the parts and The best thing was how fast I received it! I didn’t want to use my trailer until everything was back in working order. Etrailer’s fast delivery has me up and running in no time!


Very easy to install and much better than the stock super long cable. I have to imagine this will work much better than the long straight cable that was looped through the chains. Totally happy with the product.

Its still going strong and has been much nicer than the straight cable. I would definitely buy this again.
Derek - 10/25/2019


Purchased this breakaway switch to replace a bad one on my gooseneck trailer. Product is much better quality than the factory switch I replaced and was very easy to install. Hope to never have to use it for its intended purpose, but it tests good every time I connect my trailer and pull the pin to check for proper operation. The coiled lanyard cable is a really good feature and assured that the cable does not get tangled in other components and possibly activating the brakes.


I was pleased that my order got to my home before arrival date happy about that,when I had my brakeaway switch installed it started to get really hot and it started to melt ,I belive it was a defective part didn't want to make a big fuss over this it was on 25 dollars nothing was wrong with original switch just wanted a cable thar didn't hang on ground, I bought plenty of stuff from etrailer and always been pleased but not in this case what should I do? Thank you

by: had everything I needed to complete my trailer build, and at the right prices. The products are quality, with competitive pricing. delivered as promised, it was our local delivery that delayed sending the product out to my home, but one call to Pat, and the issue was immediately resolved, and I had the product that night! Great product, Great customer service!


This break away switch is well built, easy to test. I should have bought 2, I need one for my other trailer. No more finger pricks with the cable, The plastic coating and the coiled cable should help and keep it out of the way and protected.


I received my breakaway switch on time but haven't installed it as of yet. Every order I've received has been great and comes with easy instructions.
Thanks Adam E.


This product is as described, I liked it because it has the ability to swivel back under the bumper when not in use and it came with everything I needed to wire and connect a breakaway switch.


I like these breakaway switch and coiled cord combos, our cables end up cut off a lot of times. When we change out switches I always update them with this combo


Preorder service was excellent. Questions were answered and product was delivered as promised. Breakaway switch was of good quality and staff was very helpful in selecting the right product.


Great direct replacement breakaway switch with easy installation.
Fast shipment and competitive pricing from etrailer makes this an
even more obvious choice.


Been on the trailer for a year. Luckily I've never needed it, but it's showing no external wear. Cable and clip are still like new and the mount is solid.


It's super-handy to have the coiled cable, although I had to replace the carabiner with something smaller. The cable is rather long and I have to loop it back and attach it to the coupler latch. I do love the cable not getting in the way of anything.


Great product


Product arrived with in a couple of days after ordering. It is just what I needed for my Dump trailer E switch replacement.


Fast ship! Thanks. Fits my Roadmaster rig.


Looks like a very good product. However, I like the ability to disconnect the spring cord at the unit when it’s not in use. This cord is permanently affixed. I can modify it, but would prefer not to have to.


Works perfecr


Nice quality breakaway switch at a great price.

  • Replacement Trailer Breakaway Switch and Cable Recommendation for 4 Foot Breakaway Cable
    The Fastway Zip Trailer Breakaway Switch # FA80-00-2040 that you referenced has a 4 foot long cable. The breakaway cable should be longer than the safety chains according to RVIA Recreational Vehicle Industry Association. This will activate the brakes in the event you lose the trailer connection and the safety chains fail.

  • Should a Breakaway Pin Be Able To Be Pulled By Hand
    It sounds like you are saying that the breakaway pin is stuck inside the switch. If that is the case then yes, you should be able to pull this by hand though they do take a bit of force to remove but it sounds like you may be exceeding that. If the pin will not come out then it may be stuck or someone may have tried to install the wrong pin into the switch. If that is the case then it would be best to replace the two as this is not really a component that you want to leave up to chance...

  • Can Trailer Breakaway Kit be Used without a Battery
    If you didn't have a battery used with your breakaway system there'd be nothing to power the brakes in the event of a disconnect so you couldn't use just a switch like the part # FA80-00-2040 by itself. You'd instead need to use a whole system like the # 20099 and you'd be set. I attached a help article that covers more info on these for you to check out as well.

  • Troubleshooting Trailer Brakes Being Locked Up With 7-Way Disconnected From Tow Vehicle
    It sounds like you have an issue with your Breakaway Kit # 20099. This is where the power is coming from to lock your trailer brakes when it is not connected to your vehicle 7-way. You will want to check to ensure the disconnect is fully seated and the wiring for it is not damaged. We do have a Replacement Switch # FA80-00-2040 if your switch is allowing power to flow through the switch with the plug in place.

  • Is There a Replacement Pin for Bright Way Group Model 2384 Breakaway Switch
    I do have an option for you but I wasn't able to reference a Bright Way Group Model 2384 Breakaway Switch/Pin. Therefore, in order to ensure compatibility you'll want to replace both the switch and pin using one like the Replacement Breakaway Switch for Bright Way Trailer Breakaway Kits part # 3802348 which would be a very easy replacement as there are only two wires and a single mounting hole for the switch. If you want to change styles, I recommend the Fastway Zip Trailer Breakaway Switch...

  • Trailer Breakaway Switch Compatible With 12-Volt RV Battery
    Yes, 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.

  • What Separate Power Source Needed For Breakaway Switch
    It looks like you have everything wired right so if everything is working then you are good to go on wiring. With regards to the power source, most states require a separate and dedicated power/battery source for your breakaway system so the 12V pole on your junction box will not work. If you want an entire breakaway kit that includes a breakaway switch, I recommend the Hopkins Engager Push-To-Test Trailer Breakaway Kit, Item # 20099. This kit includes built-in battery charger, push-to-test...

  • Recommended Fastway Coiled Cable Breakaway Cable for 5th Wheel Trailer
    You can use either a 4 foot cable like # FA80-01-2140 or a 6 foot cable like # FA80-01-2160. Either will work well on a 5th wheel trailer. Where you mount the breakaway on the trailer will dictate the best location for you to allow trailer turning and also a quick engagement if your trailer were to breakaway from your tow vehicle. If you don't have the entire assembly, you can use # FA80-00-2040 for the 4 foot cable or # FA80-00-2060 for the 6 foot cable. I've attached an article...

  • Replacement Pin Recommendation for Fastway Weight Distribution System
    The only replacement pin I can recommend for a Hopkins breakaway kit is the part # HM20012. If you wanted the coiled design of the Fastway kit you'd need to replace the switch too with the part # FA80-00-2040 and you'd be set. While the pins aren't all universal between brands we've found that the switches are.

  • Replacement Brake Away Cable For Frayed Trailer Breakaway Cable
    You can trim your current Breakaway Cable # 2010-A and fasten a new loop as long as you ensure it is long enough to not activate the brakes when you are turning your trailer. You will need to ensure that the repair is strong enough and that the remaining portion of the cable is still in good condition. I recommend replacing the cable with either the Fastway Zip Coiled Trailer Breakaway Cable # FA80-01-2140 or replacing the entire switch with the Fastway Zip Trailer Breakaway Switch with...

  • Troubleshoot/Repair Damaged Trailer Break Away Braking System
    It looks like the interior of the switch was damaged. It's not a big deal assuming it's an electric breakaway system. You can just replace the switch assembly very affordably. The switches use two wires to connect, so they're not system specific. I like the switches offered by Fastway that use a coiled cable that won't drag and feature a carabiner that makes it simple to attach to the tow vehicle. The switches are available with a 4 foot cable as part # FA80-00-2040 or a 6 foot cable as...

  • Does Prodigy RF Brake Controller Act As Breakaway System
    The Tekonsha Prodigy RF Wireless Trailer Brake Controller # TK94FR does not function as a standalone breakaway system. You need to keep using your current breakaway system with this as they are separate systems. The replacement breakaway switch part # FA80-00-2040 comes with a cable that is 4 feet in length and will work great but will require you to replace the entire switch with this kit.

  • Trailer Brake Breakaway Switch & Cable
    Since your travel trailer has onboard house batteries, the break away brake will be powered by those. To replace the breakaway switch and/or cable I recommend the Fastway # FA80-00-2040 which includes the tongue mounted switch. If you have the switch and only need the lanyard I recommend the Fastway # FA80-01-2204. I have this same line attached to my travel trailer. I like that the coiled line keeps it away from the ground and the large carabiener clip makes it each to hook on to the...

  • Can Breakaway Switch By Itself Be Used If Trailer Already Had Battery
    If you have a battery already on your trailer that's getting a charge and would be adequate to hold the brakes of your trailer in the event of a breakaway you could wire just a switch from it to your brake output circuit and you'd be fine. For that you'd only need a switch like the # FA80-00-2040 for a kit with a coiled cable or part # 2005-P for a kit with a straight cable. The battery setups like the part # 20099 would only be needed if you also needed a battery to power the system.

  • Replacing Missing Trailer Emergency Breakaway Cable and Pin For a Travel Trailer
    While we do have a couple Replacement Cables and Pins # 3802350 & # SM99905 they are not always compatible with every Breakaway Switch # HM20010. I recommend replacing the switch with the Fastway Zip Trailer Breakaway Switch with Coiled Cable # FA80-00-2040. This uses a red coiled cable that is easy to see and notice if it is missing. Also since it is coiled it is less likely to drag on the ground like the straight cables and become damaged. To be able to move the trailer you will need...

  • Replacement Breakaway Switch for SMI Stay-IN-Play Towed Car Braking System SM99251
    If you needed only the Switch Pin for your SMI Stay-IN-Play Duo supplemental braking system # SM99251 you could use part # SM99905. But for a complete replacement breakaway switch you can use any of the kits we offer, shown on the linked page. Since these all function the same way they are not brand- or system-specific. Examples of suitable items are # HM20014 and # FA80-00-2040. These and all others are shown on the linked page.

  • Troubleshooting Trailer Brakes Locking Up Without Applying Vehicle Brakes
    The brakes on your new RV trailer can be activated either by the brake controller or the trailer's own on-board emergency breakaway system. I have not heard of an issue with the Echo # C51180 before now, and while it is possible the unit has an internal malfunction I suspect the problem is more likely to be in either the trailer's breakaway system or within the 7-way wiring on the Audi or the trailer. For the trailer brakes to lock up without you pressing the brake pedal they would need...
