Today we're going to take a look at the Decca jacketed 2 wire 10 gauge brake wire and this is sold per foot. I have a sample here, this is just to show you that this combination of the 2 heavy duty 10 gauge wires. They're jacketed individually and then all together. It's perfect for when installing a trailer brake controller on your vehicle. The 10 gauge duplex brake wire made with the 2 plastic insulated primary wires are laid parallel and the wires are covered with this high quality plastic jacket that protects the insulated conductors. The conductors are color coded for easy identification.

You can see a white and a black. This does meet all the SAEJ1128 specifications up to 50 volts and the insulation is rated to 105 degrees Celsius. Basically what this is used for is one wire is connected to your brake controller which carries the power back from the trailer brakes while the other is connected directly to the vehicle battery for an auxiliary power supply pin in the trailer connector. What's nice is having both of these wires in the same jacket. It makes running them from the back to the front of the vehicle very quick and easy.

That should do it for the review of the Decca jacketed 2 wire 10 gauge brake wire and this is sold per foot.

Deka Jacketed 2 Wire, 10 Gauge, Brake Wire - per Foot - 10-2-1

Average Customer Rating:  4.8 out of 5 stars   (303 Customer Reviews)

This combination of 2 heavy-duty 10-gauge wires, jacketed individually and then together, is perfect for installing a trailer brake controller on a vehicle. Sold per foot.


I was looking for two 10 gauge jacketed wires that could also be easily separated. Most of what I found were wires molded into the jacket which would make it very hard to strip and separate them where needed. etrailer is one of the very few places able to supply such wire.


Seems like a good product, but it's very expensive and it wasn't necessary for my installation. Seems like they don't really know what I need for my mass produced American truck.


As with past orders on etrailer I received nothing but superb service, advice and recommendations for this project; replacement and upgrade to automatic self adjusting brakes on a two axle travel trailer. Parts were top of the line and installed flawlessly. Highly recommend etrailer once again.


It’s just like the wiring in your house. Very thick and abrasion resistant insulation. Ran it from my 7 pole plug through the frame to the front of my truck behind the front drivers side wheel well.


I think E trailer is the only place to get this. Perfect for trailer wiring and brake controller feeds.

In the video it said get the 10' of this wire. My fault, I didn't notice when I bought it that it was by the foot. It shows a roll so I never put two and two together. So I received a 2'section which is completely worthless.


I purchased this cabling to replace existing trailer brake wiring that had failed due to a short circuit. It is heavy duty by sill easy to work with. I would certainly order it again if I have a need. As always provides excellent products and customer service.


Good quality wire, works well and easy to use.



Still working well, no issues, seems to be very high quality.


Great product! I was able to complete my electric brake controller installation with ease!!! Great instructional video.


Services fantastic.


Heavy duty wire that will last the truc k!!!


Products I received were fine. The shipping was very quick, and arrived quickly. Where etrailer really shined was in their contact help. My email was answered quickly, with alternate suggestions (which were both a closer match and cheaper alternative to my pick) and clearly explained by my online contact. They were a very big help.

I'm a repeat customer of etrailer, and never had an issue. Good people there, period.


Great for trickle charging my trailer winch battery


These things are major time-savers! Bolt the whole assembly on, wire it up, and go! Can't beat the price either - would cost quite a bit more buying the parts individually. Made a huge difference in stopping power on my 18' Dively car hauler, 9990 GVWR. The brakes were 6 years old at the time, and had tens of thousands of miles on them - abusive miles too, with shoes seizing and dragging, electrical failures causing some to work 3x as hard as others, stop and go MA traffic, etc.

While I was at it, I also grabbed 30' of Deka jacketed 2-wire 10 gauge brake wiring, and redid the whole system from the plug back. I also removed the drums, had them turned at a local garage, and installed brand new bearings, races, & seals. The improvement in stopping power was nothing short of amazing.

I went from having my Tekonsha P3 on boost level 3 at 11 volts +, trailer UNLOADED, to running boost level 1 at 6 volts with 4,000 lbs. on the 2k lb. trailer! BIG difference in stopping power!

Seems my brake backing plate installation review got posted under the Deka wire ... but anyway ... the wire is working great a year later. Gone roughly 2k miles with several hundred miles in corrosive road salt. I ran the wire through washers I welded to the inside of the frame. Holding up well with the constant abrasion on our endlessly potholed roads here in Massachusetts. Well worth the price - brakes have been working perfect ever since!


Great place to buy trailer supplies!


Wiring has been good I would recommend it. When I order 33ft however, I received 30 foot roll and another 3 foot piece, not a continuous roll of 33ft. Disappointing.


My tow vehicle does not have factory connections for trailer wiring. Used this cable for trailer brakes and auxillary power. This cable is just what I needed to run from rear to front of my vehicle on the underside. The sheathing protects the wire from the elements. The shipping was quick.



After one year of use, no problems what so ever.


Good gauge of wire and well insulated would buy again


I had a great experience. Got the product with no problems.


Hello, this is my second order from the guys at, and let me tell you they ship SUPER FAST, and the constantly keep communicating about your order. These guys don't play around, hats off to y'all. This product worked out great, i did have to cut about 1/3 of the 10ga wire though to get it to fit in my Bargman 7-way. But at least i wont get a current drop though. Very nice insulation jacket too. (Not the hard plastic crap) thanks again guys for great customer service

Great product!


This item was recommended to use with electric brakes. Made sense. When arrived, I found that the wire was to large to fit in the axle tubes and trailer conduit. Recommend that you check to make sure it fits before buying. The product is high quality, and would work great for the application if it fit.

Everything has worked flawless


etrailer products and service are excellent! With their helpful videos and staff (plus a little help from Curt Manufacturing and our teardrop trailer manufacturer (CampInn)) I was able to install electric brakes on the trailer, and a controller in my vehicle by myself. I had never installed electric brakes before. Everything works perfectly!


Amazing and professional service! I had to keep myself from completing the job too fast and rushing through steps. Attention to details is a must when working with electrical systems and with some patience I was happy to say I completed a successful job. I will be a repeat customer!



As a military member, I am moving again after only a year and I hooked up my trailer to my truck and all of the components worked! I am very pleased with this product.


It’s wire, worked like it should for the project I had.


I love dealing with Etrailer...Excellent customer service....I ordered the Teconsha prodigy p3 brake controller, the universal installation kit for the brake controller...received it promptly...Instructions could not have been any simpler...Installed it on my 2004 winnebago Itasca motorhome and it works perfectly...I have ordered from you all in the past and just placed another order today...You all are on the ball...Thanks Etrailer!!

  • Gauge Wire Recommendation for Wiring up Trailer Brakes
    I'd recommend using 10 gauge wire like part # 10-2-1 (sold by the foot) for the brake power and ground wires as this will be more than adequate and will ensure you get plenty of amperage to activate the brakes.

  • What Would Cause Voltage Drop Between Front of Trailer and Brake Assemblies
    Typically if there's a large voltage drop like you mentioned the issue is the longer run of wire not being a heavy enough gauge of wire. You'll need to use 10 gauge wire like 10-1-1 to make the run from the front of the trailer back to the assemblies and you'll see the voltage drop be much smaller.

  • Troubleshooting Electric Drum Brakes That Do Not Grip Despite Functioning Magnets
    Based on your troubleshooting efforts so far I suggest that you test the trailer brakes without using a vehicle and brake controller; you can test the trailer brakes directly by applying +12V power and ground to the appropriate contacts on the trailer plug. Please refer to the linked photo. A set of jumper cables and 10-gauge wire like # 10-1-1 or # 10-2-1 make it simple enough to "hot wire" the brake circuit with the full power from your vehicle battery or a well-charged spare.

  • Testing an Electric Trailer Brake Controller
    The ground may be sufficient but it wouldn't hurt to test it using an alternate ground location as well. Perform the test using just the manual override and not the brake pedal. Make sure the controller is set to the maximum output level and that it is mounted within the range specified by the instructions. Also make sure that it is not tilted or turned to the side. If the controller you are using has a leveler knob, you will need to make sure it is properly adjusted according to the...

  • Running Wire For A Brake Controller Through The Firewall Of A Vehicle
    To run a wire through the firewall of your Mercedes-Benz GLK350, you will want to first check for wires already run through the firewall. If you can use the same location, that minimizes any issue. If you need to use a different location, check for grommets first. Often there are rubber grommets that cover a hole that is already in your firewall and removing that grommet, cutting or drilling a hole and replacing it around the wire is the next best option. The last option is to drill...

  • Ideas to Prevent Rodents from Eating Trailer Wiring
    I did some searching around on the internet and came up with a few interesting tips to prevent rodents from eating vehicle/trailer wiring. Here is what I found: Noise will keep the rodent's away. So a portable radio would work for this. Flashing lights, so like a strobe light or any other type of blinking light. Putting a garden gnome near the trailer. Spraying the wires with capsaicin. I normally don't recommend this, but getting a cat might keep them away. Mouse traps. For fish wiring...

  • How to Check Electric Brakes and Wiring on a 36 Foot Gooseneck Trialer with Brakes on Two Axles
    It sounds like you had a short on the electric brake controller wiring at some point, since the wires are black. This indicates the wiring was overheated. The first thing I would do is check the 7-Way connector on the trailer and the truck for proper wiring. I attached a link to our wiring page for you. This page shows the correct placement of wires inside the vehicle and trailer side 7-Way connectors about 1/2 way down the page. Once you are sure the vehicle and trailer connectors are...

    You actually don't need an adapter. The two 4-way types are perfectly compatible with each other. The one 4-way having 5-wires is a wish bone setup that has a wire ran for the running light circuit for each side of the trailer.

    If all the other functions for the 7-Way on your 2015 Ford F-250 are working correctly, but you aren't receiving any power at the 12V pin, then I recommend checking for any missing or damaged fuses on the truck. I took a look at the online owner's manual for your F-250 and found that there should be a 25 amp cartridge fuse located in the #90 position inside the engine compartment power distribution box. This particular fuse is for trailer battery charge/12V power. Make sure this fuse is...

  • Where Does Brake Output Circuit on Trailer Wiring Run to On Trailer Magnets
    You are super close to having the brakes functional on your trailer. Run the blue wire from the brake output pin to either one of the wires that are coming off of the brake assemblies and then ground the other and you'll be done. Brake magnet wires are not polarity sensitive either so either can be ground or power.

  • How To Order Deka Jacketed 2-Wire 10 AWG Brake Wire
    The Deka Jacketed 2 Wire, 10 Gauge, Brake Wire # 10-2-1 is sold by the foot, so you'd need to order based off the footage needed. For example, if you needed 4 feet you'd need to order 4 and so on. So if you're two feet short, you'd need to order two more sections. A good rule of thumb is to order more than you need, it's always better to have a bit too much than not enough.

  • What Gauge Wire Should be Ran When Installing Brake Controller
    For all of the circuits you mentioned you would want to use 10 gauge wire like our part number #10-1-1 which we sell by the foot. For the power and ground for the controller that runs to vehicle battery a double bonded wire setup like part # 10-2-1 might be a better option for a neater install. This is essentially two wires bonded together so its like running one wire but then you split them off at the ends.

    I have a solution for you, but I checked with one of our contacts at Freightliner, who manufacture the chassis that the 2003 Fleetwood Providence is built on, and they mentioned that the pre-2004 chassis does not have an included adapter plug for the easy installation of a brake controller like the Tekonsha Prodigy P2 # 90885.

  • Is 14 Gauge Wire Too Small for Electric Trailer Brakes
    Yes, 14 gauge wire seems too small. I would go with 10 or 12 gauge. For 10 gauge you can use # 10-1-1 and for 12 gauge use # 12-1-1. These wires are sold in increments of 1 foot. So if you needed 20 feet of wire you would enter 20 in the quantity box. The 12 gauge would be the best option. You mentioned replacing the brakes with the Nev-R-Adjust a year ago. It has probably been long enough, depending on how many miles were put on the trailer, but just to be sure even Nev-R-Adjust brakes...

  • What Gauge Wire Should Be Used to Wire Up Trailer Brake Assemblies
    If it were me I would go with 10 gauge wire. For that you would want part # 10-2-1. Some people use 12 gauge wire and have success, but honestly I would rather have to heavy of gauge wire than not heavy enough. So to be on the safe side I would go with the 10 gauge. The 10-2-1 is sold by the foot, so you will need to order a quantity of how many feet you would need. I attached an FAQ on trailer wiring for you to check out as well.

  • Which Wire Sized Should be Used for Electric Trailer Brakes
    You should use 10 gauge wire for electric brakes which is pretty much the standard size for electric braking applications because it can handle the amperage better over the long distance from a brake controller to the electric brakes. For a nice duplex cable with two 10 gauge wires you can use # 10-2-1 which is sold by the foot. I have also included a link to our help article on adding electric drum brakes to a trailer.
