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.

Great, no problems

Good quality wire, works well and easy to use.


Works as expected. Good company to deal with.


Outstanding customer service.. parts delivered promptly and better quality than expected.. I have recommended your company to anyone working on a trailer, and look forward to my next project..


Way to thick to be used for electrical brakes

The Deka Jacketed 2 Wire part # 10-2-1
Deka Jacketed 2 Wire, 10 Gauge, Brake Wire - per Foot
is designed to install an electric brake controller where one wire is connected to the brake controller and the other wire is connected to the vehicles battery. I recommend 10 gauge primary wire part # 10-1-1
10 Gauge Primary Wire - Blue - per Foot
to install brakes on the trailer which is the standard gauge for trailer brakes.

good brake wire in a heavy duty jacket


Just what the doctor ordered!


Great service.


Great utility wire


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!
Smitty S - 11/05/2017


Wire is average. Nothing good or bad to note.


Great for trickle charging my trailer winch battery


Sales lady was terrific and very helpfu l.


Heavy wire, jacketed is perfect for under a trailer where the water spray, dirt and dust is heavy. I did shrink tube everything just so no corrosion gets in where it doesn't belong. Great wire!


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.
Richard - 12/26/2014


Great quality!


I appreciate the phone call to let me know the parts I ordered were on back order. Other parts were available immediately and so I switched up the order. This saved time in finishing my project and the parts worked perfectly. Excellent quality parts. Excellent customer service! Thanks


Haven’t installed yet but came in in good condition and in’s timely manner


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!
Michael F - 04/01/2015


Quick to fulfill order and ship.


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
Patrick P - 10/11/2017


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!


So easy to order and so fast shipping. Got it sooner then they said. Glad I found this site.


Fast shipping good product

  • 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.

  • 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. If you...

  • 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...

  • 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...

    The temperature rating for the 10 Gauge Jacketed 2 Wire is 105 degrees celsius. According to the information I found, 10 gauge wire with a 90 degree celsius insulation is rated to 40 amps. With 105 celsius insulation, it should be able to handle over 40 amps.

    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...

    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...

  • 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.

  • Electric Brake Controller for 2003 Fleetwood Providence on Freightliner Chasis
    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

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.

  • Parts Needed to Rewire Trailer Brakes to Junction Box
    The only parts you need is the wiring, butt connectors # 05732-2, and ring terminals # DW05705-1. The wires coming from the brakes do not have polarity so either can be used as the ground or power wires. Depending on how you have the brakes grounded you can run individual wires using # 10-1-1. We also have 2 wires jacketed together, part # 10-2-1. This may be an easier solution. Both are sold by the foot.

  • How to Wire Electric Trailer Brakes on a Boat Trailer
    To run the brake lines on the trailer, you don't need the dual cable. I'd recommend using 10 gauge wire, part # 10-1-1 which is sold by the foot. Run the wire from the trailer connector back to the axle, cut the wire and strip the end. Use a butt connector like part # 05732-2. Run a lead to power each brake assembly out of the other side of the butt connector. Use some liquid electrical tape, part # SWC50122 to seal the connection. At each brake assembly, the brake magnet has two leads....

  • Can Several Strands of Wire be Combined to Make a 10 Gauge Wire
    You would have to remove all the insulation from the wire that you have and then braid the strands together and find a way to re-cover it with the properly rated insulation. It would be easier to just get new wire and avoid all of that work and hassle trying to find, purchase, and re-bond insulation for the wires. It is also possible that the various wires you have are not all the same type. Some could be made of different materials, grades of copper, or rated for different amperage draw....

No fuse will be needed for the solenoid center pin as its function is really only to close the circuit to let voltage pass through the other two pins.

I suggest using a circuit tester like # PTW2993 to test your wires. You have a closed circuit on your brakes that should be an open circuit.
