Video Transcript for Deka Wiring 12-2-1 Review

Today, we're going to review part number 12-2-1. This is the Deka Jacketed 12 Gauge 2 Wire Brake Wire. This is sold per foot. This duplex brake wire is made with 2 plastic insulated primary wires right here. You can see it at the end. They are laid parallel and they are covered with this high quality plastic jacket which protects the insulated conductors.

Now each conductor is color coated. You can see black and white. Usually when this is used on brake applications, the black would be your power, the white would be your ground. It gives nice, easy identification. This is designed for use with 50 volts or less. Now each wire gauge is a 12 gauge measurement and this wire is sold per foot.

As you can see right here, I do have 1 foot pulled off but you can order as many feet as you'd like. That should do it for the review on part number 12-2-1. This is the Deka Jacketed 12 Gauge 2 Wire Brake Wire sold per foot. .

Just started to install the new brake assembly on the trailer and so far so good. The product is of good quality. The only problem so far is the brake wire you sent is larger than the wire that was on the trailer and now I am going to have to find larger scotch lock connectors to fit the wire. The shipping was real good and fast. Will order from you again when I need anything for the trailer, thanks again Ray 445984

I did not use this wire for a trailer but I did use it to run power from my trucks battery through the engine bay under the cab and into a vent on the back of the cab for a ham radio. The jacket is tougher than I expected, wire soldered great. Great value. 138641

I needed to retrofit my twp axel trailer to get it state inspected. I bought everything I needed from etrailer. I love one stop shopping! I was very pleased with the delivery time and the high quality of parts I bought. The brakes work like a charm. The only thing that I would suggest for the company is to recommend break away automatic braking device when selling these brakes. It was required by law in Pa and I had to buy an automatic brake locally. I would do business with these folks any day. I highly recommend. 361736

Thank you John C. 423008

by:

I didn't buy anything special, just some #12 and #10 brake hook-up wire. etrailer was one of the very few places that I was able to find the wire I needed. They sell it by the foot rather than by the bulk coil like most places, so I was able to buy only the amount I needed. Also, the price was right and I was able to rewire my entire trailer and all four (4) breaks for a very reasonable cost. 58112

E trailer did a fantastic job. Before order: Technical support / help was excellent. Goal, conversion of a 1998 Floe snowmobile trailer from surge to electric brakes. Problem, due to time and corrosion, I could only supply partial part numbers, spindle diameter. etrailer did a fantastic job, researching, and getting me the correct part numbers, so I could order. Julie did a great job. She was very timely, communicated clearly and honestly, and just “kept me in the loop”. I received the order came on the projected date, complete and undamaged. Excellent. I would highly recommend etrailer, for your part needs. 439112

  • Adding Trailer Brakes to a Timbren Axle-Less Trailer Suspension System
  • Yes, it is possible to add brakes Timren Axel-Less Trailer Suspension System. The Timbren Axle-Less Trailer Suspension System - 4" Lift Spindle w/Flange - Off-Road Tires - 2.2K, # ASR1THDS03, that you were looking at has the brake flange mounted, so it is ready to add brake assembly and hubs to. I'd recommend getting the Electric Trailer Brake Kit - Self-Adjusting - 10" - Left and Right Hand Assemblies - 3,500 lbs # AKEBRK-35-SA . You would then pair these with the Trailer Hub...

  • Complete Electric Brake Installation for 2,000 lb Trailer Axle
  • With the axle measurement and the bearing number, I can confirm that you have 2,000 lb capacity axles on your trailers. You will want to get the Brake Mounting Flange, # 4-34, to weld onto each side of each axle. With that flange in place, you will want to mount the 7 inch Electric Trailer Brake Assembly # AKEBRK-2L on the left side of the axle and the # AKEBRK-2R on the right side of the axle. These are nearly identical parts, but installing on the correct side is very important....

  • Recommended Parts For Dual Axle Trailer Complete Rebuild
  • For your trailer rebuild, I recommend the Dexter Trailer Axle w/ Electric Brakes - EZ-Lube - 5 on 4-1/2 Bolt Pattern - 89" - 3,500 lbs for your tandem axles, # 35545E-ST-EZ-89. You will also want the U-Bolt Kit for Mounting 3,500-lb, Round Trailer Axles - 5-1/2" Long U-Bolts, # APUBR-1. For suspension I suggest the 4-Leaf Double-Eye Spring for 3,500-lb Trailer Axles - 25-1/8" Long, # SP-212275. You will then need a kit with mounts for your equalizers and shackle straps. The Tandem-Axle...

  • Electric Brake Conversion from Air Brakes on 15,000 lb Axle Trailer
  • The Dexter Electric Brake Kit w/ Cast Backing - Self-Adjusting - 12-1/4" - Left/Right Hand - 15K # 23-446-447 will fit any 15K axle that have the standard 7 bolt mounting flange. These are self-adjusting brakes so there is no need for manual adjustments after the initial installation. They are labeled left-hand (driver's side) and right-hand (passenger's side) to ensure proper placement. If you need the mounting hardware, I recommend # BRKH122510 for each axle. You will also need...

  • Installation of Solera Manual Pull Style to Power Awning Conversion
  • The Solera Manual Pull Style to Power Awning Conversion Kit, Black # LC329251 will simply require changing the heads on your awning frame and then wiring the unit. I've attached the photo from the installation manual that specifies how to wire the awning. There are specifics, but the biggest aspect not included in the kit is the wire to the battery and ground. You will want # 12-2-1 sold by the foot for your wiring. I've also attached a link to the instructions to assist.

  • Recommended Wire to Extend Length of Power Cable on Master Lock Electric Trailer Winch
  • The Master Lock Electric Trailer Winch - 2,000 lbs # 2953AT comes with power cables that are 20 feet long and does not have other lengths available. If you wanted to extend that length 5-10 feet, you would need to use 12 gauge wire like # 12-2-1 sold by the foot and heat shrink butt connectors like # DW05745-5.

  • 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.

  • Recommended 7-way Wiring Harness for Upgrading Trailer to 7-way by Adding Brakes and Reverse Lights
  • I recommend the # ET7WK junction box kit for your trailer. This kit includes a 7-Way trailer connector, a wiring junction box with mounting hardware, 8 ring terminals for 12- to 10-gauge wire, 8 ring terminals for 16- to 14-gauge wire, 10 foot of wire loom, and 1 self-tapping ground screw. You will also need an appropriate length of duplex wire # 12-2-1 to connect your brakes. The 7-way trailer plug # H20046 included in this kit will have the auxiliary wire that is used for reverse...

  • Recommended Wet Shackle Bolt And Shackle Strap For 1-3/4 Inch Double-Eye Leaf Spring
  • We do have a wet bolt that will work with the # SP-218275 leaf springs you said you are going to use. I recommend part # 34007-187-00. This bolt measures 3-7/16 inches long and the usable length is 3-inches. The locknut for that can be used with this wet bolt is sold separately and is part # 192600. For the shackle straps, the closest we have to the 2-1/2 inches you said you need is part # 115052GALV. This strap measures 4-inches overall and the center to center for the holes is...

  • Recommended Brake Controller and Wiring for 2003 BMW X5
  • Don't worry I can help, but for a boat trailer with a 4-way you shouldn't need a brake controller because they do not have electric brakes. A standard brake controller is not recommended to install on your vehicle due to low voltage brake light switch. A standard brake controller like the Voyager will not be able to be used on your X5. If your planning on adding electric brakes to your boat trailer then you will want the RF brake controller # 90250 (mounts on the trailer) and the 7-way...

  • 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.

  • Do all 3,500 lb Trailer Axles Have the Same Bearings
  • In almost all cases 3,500 lb axles will all use the same bearings. If your trailer has a Lippert or Dexter 3,500 lb axle then yeah they would be the same. But to be safe it won't hurt to pull them off and get the numbers. If you are sure you need a 5 on 5 inch bolt pattern we have the part # AKHD-550-35-K which would work and fit the spindle. This hub uses bearing numbers L68149 and L44649. I attached a help article on bolt patters for you to check out as well.

  • Installing a 7-Way Connector at the Rear of a 5th Wheel Trailer with a 4-Pole Connector
  • To get a functioning 7-Way at the rear of your 5th wheel trailer that has a 4-Pole you will want to install the Adapter 4-Pole to 7-Pole and 4-Pole # 37185 which can be mounted to your bumper using the No-Drill Mount Bracket # 18140. To get the 12V Power and Brake Controller signal from your Chevy Duramax you will then need to run Jacketed 2 Wire (Brake Wire) # 12-2-1 up to the 7-Way on your Duramax and splice it in. If Butt Connectors are needed use part # DW05745-5. If the Auxiliary pin...

  • Why Use 10-Gauge Wire # 10-2-1 Rather Than 12-Gauge # 12-2-1 for Electric Trailer Brake Circuits
  • You are correct that Deka Jacketed 7-Wire # DW04914-1 uses 12-gauge conductors for all but the ground wire, which is 10-gauge. There are several variables with trailer brake wiring that we generally do not know when our customers ask about the wire gauge that should be used for re-wiring a trailer's electric brakes. The length of the trailer (and the required wiring) and the number of axles (and brake assemblies) can vary and when we do not know all of the particulars for every installation...

  • Can Electric Brakes be Used on a Boat Trailer
  • Traditionally, trailer manufacturers did not use electric brakes on boat trailers because the brake magnet wiring and trailer wiring did not always have the best insulation or water protection. These days, more and more manufacturers are using electric brakes on boat trailers due to improvements in wiring insulation and heat shrink connectors. If you are going to use electric brakes, I strongly recommend using heat shrink butt connectors, like part # DW05745-10, when splicing the wires...

  • What are the Dimensions of # 12-2-1 Jacketed Brake Wire
  • I went to our warehouse and pulled some of this Jacketed 2 Wire, part # 12-2-1, to measure for you with a pair of digital calipers. The width of the 2 wires with the jacket measures .364 inches. It measures .209 inches thick. Each individual wire when removed from the jacket measure .122 inches thick. I have also attached links to some of the connectors that can be used with this wire. For wiring brakes on a trailer, I would not recommend using 12GA wire. Instead I would recommend...

  • Troubleshooting an OS and a CS Code On Electric Brake Controller
  • On the Valley Journey brake controller, the OC code indicates that the manual override lever is being applied and there is no trailer connected. The CS code indicates there is a detected short circuit. Often the cause of this is corrosion at the trailer connector. Check the vehicle side and the trailer side for corrosion. If corrosion isn't the issue, then I would start on the vehicle side. First, do you have those codes without a trailer connected? If not, then we know the problem...

  • Installation Of ETBC7 Kit Based On Diagram
  • You technically can run one hot lead from the battery and split it out before the circuit breakers and it will work. I prefer to use the separate wires like # 12-2-1 just to keep from splicing an additional time. Basically you would be taking the surface area that the current runs down and splitting it instead of giving it the entire pipeline to save a foot or two of wire depending on where you place your circuit breakers. If you want to save that amount of wire, it will work the way...

  • Recommended Junction Box For Individual Trailer Brake Wiring
  • My recommendation for the junction box is the Pollak 10 terminal Junction Box, # PK52248. This will give you individual terminals for your 8 contacts. I'd suggest using the other two for a hot supply line and a ground line so you can just add jumper wires within the junction box itself. Your application will be a customized one, but this additional junction box will allow you to have the simple troubleshooting you desire. I would not go smaller than 12 gauge wire for trailer brakes,...

  • Brakes on My 5th Wheel Are Not Working But Trailer Lights All Work Fine When Connected
  • If you have electric brakes or electric over hydraulic brakes, the first thing to do in either case is take a circuit tester like # PTW2993 to test your signal from the brake controller to the trailer connector at the rear of your 2015 Ram or the bed if you have the relocation attachment like # 41157. With the alligator end of the tester clipped to a clean ground, touch the probe to the 5 o'clock position while hitting the manual override on your brake controller. You can also use a 7-way...

  • Installing A 12V Outlet For Running A Portable Refrigerator In SUV
  • To run your portable fridge in your SUV, I recommend you use the Roadmaster 12 Volt Outlet Kit, 20 amps # RM-9332. This will connect directly to your battery and will then help your smart alternator to kick in as needed. You may want to consider using # 12-2-1 for any wiring length you need to add.

  • Wiring Needed to Power MaxxAir MaxxFan Trailer Roof Vent From Trailer Battery
  • If you were to run your MaxxAir MaxxFan Trailer Roof Vent w/ 12V Fan - Manual Lift - 14-1/4" x 14-1/4" - White # MA00-04000K off of a deep cycle battery you'd just need to run a power and ground wire from the battery to the vent motor and you'd be set. We have a bonded set of 12 gauge wire as part # 12-2-1 which you can run from the vent to the battery and you'll be set.

  • Troubleshooting 5th Wheel Gooseneck Wiring Installation on 2004 Ford F-350 with Factory 4-Way
  • For your 2004 Ford F-350 you will utilize your factory 4-way and then wire in an adapter and the wiring for a brake controller. For your application, I recommend the Hopkins Endurance Multi-Tow 4-Way Flat to 7-Way RV Trailer Adapter w/ 4-Way Vehicle End Plug # HM47180. You will plug your 4 way into this, then use a screw to ground the white wire with ring terminal. Then you will use the # 12-2-1 wire to run your 12V power wire to the red wire, the brake controller output wire to the...

  • Replacing Factory 4-Way on 2006 Ford F-150 with 4-Way/7-Way Connector
  • Yes! The Hopkins Plug-N-Tow # 40185 is a plug and play solution for replacing the factory 4-Way on your 2006 Ford F-150. To add a 7-Way/4-Way connector you would then need the Hopkins # 37185. This connects directly to the 4-Way and then has additional wires that you can connect to wiring run to the rear of your pickup for it to be fully functional. You can mount the Hopkins connector with part # C57202 to avoid drilling into your trailer hitch. If you want to permanently install...
