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.

Replace your trailer breakaway device with this durable switch kit that features a coiled cord. No more dragging or fraying. No need to wrap cable around your trailer frame.

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. 485396

- FA80-00-2040

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. 431289

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. 286651

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 431206

- FA80-00-2040

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. 576360

- FA80-00-2040

This is a great product, built very well. I'm glad I bought this type. 582391

- FA80-00-2040

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. 582326

Product arrived with in a couple of days after ordering. It is just what I needed for my Dump trailer E switch replacement. 489062

One came with my new trailer. I liked it and am using it again. 480292

Seamless service. 466873

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. 420535

Very nice product! Hubby installed it in less than a half hour and is very pleased. Good quality materials and we feel much safer on the road now! 411582

- FA80-00-2040

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. 394783

- FA80-00-2040

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. 388305

- FA80-00-2040

My whole order came in quick and all seems to be great quality. Can't wait to get everything installed 378592

- FA80-00-2040

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. 364121

- FA80-00-2040

Great direct replacement breakaway switch with easy installation. Fast shipment and competitive pricing from etrailer makes this an even more obvious choice. 276906


Ask the Experts about this Fastway Accessories and Parts
Do you have a question about this Accessories and Part?

  • 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.

  • 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.

  • 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.

  • 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 best length for the cable of a breakaway system like the one that you referenced will be where the pin would get pulled right as the trailer would come uncoupled but also has clearance to allow the trailer to make tight turns without getting pulled. The reason for this is that if the trailer would come uncoupled and the safety chains were to catch the trailer you would still want...

  • 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...

  • Does Prodigy RF Brake Controller # 90250 Act As Breakaway System
  • The Tekonsha Prodigy RF Wireless Trailer Brake Controller # 90250 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.

  • 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.
