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. .

Ask the Experts about this Deka Accessories and Parts

  • One Side of Trailer Brakes Work But Other Side Does Not But Uses Same Wire
    It sounds like the left side may have a bad ground in the system or a loose ground. I would check over the complete wiring system and make sure all grounds have a good metal contact and no rust. Also check the wires to make sure the protective coating is not worn and that there are no bare wires exposed. The connector from the vehicle to the trailer could also be corroded, you will want to check inside the connector to make sure. If there is not corrosion, it would be a good...

  • 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.

  • 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.

  • What Wire Gauge Should be Used for Electric Trailer Brakes?
    It would be fine to use either 12 gauge wire # 12-2-1 or 10 gauge wire # 10-1-1. However, we generally recommend using the 10 gauge wire for running the 12V power to your electric brake to avoid the wire potentially overheating.

  • 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...

  • 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.

  • 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...

  • Troubleshooting One Brake Assembly Locking Up On Trailer When Other Three Work Fine
    For the trailer brake on one of side of your tandem axle trailer to lock up, the malfunction is in the brake assembly or the wires leading to it. I recommend checking the wires for power, to make sure you are getting correct voltage and amperage that would not lock that one assembly up. I recommend using a meter like the Powerbuilt Digital Multimeter # BTMT15. I'd then check the magnet itself. I've attached an article to assist. If everything there checks out, I'd check the bearings...

  • Is Deka Wire Available in 10 and 12 Gauge?
    We have both of the Deka wires you were searching for. Deka 12 Gauge Jacketed 2 Wire # 12-2-1 and Deka 10 Gauge Jacketed 2 Wire # 10-2-1. Each of these products is going to be available by the foot; simply input the total number of feet you need of each in the "Quantity" box. I've added links to a couple review videos of these products for you to look at.

  • Trailer Running Lights No Longer Working with 2015 Dodge 2500
    I would suggest using a circuit tester, like the Powerbuilt Circuit Tester - 6V, 12V, and 24V Systems # 40376, to check your vehicle side connection first. If you have a 4-way flat connector, check the brown wire directly next to the ground post with the probe while the clip is connected to a clean ground. If you have a 7-way connector, the brown tail light wire will be at the 11 o'clock position. If you have a power to that connector, then the vehicle is working correctly. If you do...

  • 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....

  • 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...

  • Trailer Brakes Not Working On A 2016 Chevrolet Silverado 3500
    The first thing you will want to do is check the inside of both the vehicle's and trailer's connectors for debris or corrosion. If corrosion is present, you will then want to spray some electrical parts cleaner on the inside of the connectors to clear the debris. The next thing you will want to do is test the 5 o'clock pin at the back of the vehicle's trailer connector to make sure it is receiving power when the manual override on the brake controller is activated, you will need to have...

  • 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.

  • 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.

  • 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...

  • 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 7-way Wiring Harness for Upgrading Trailer to 7-way by Adding Brakes and Reverse Lights
    I recommend the # e99011 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...

  • 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...

  • 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,...

  • 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.

  • 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...

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...

    For your Greystone 26" Curved Electric Fireplace with Remote Control # 324-000066 (model F2611E) the trim simply lifts up to allow access to the mounting screws. I've attached a video to assist. If unplugging the unit doesn't work, then I recommend checking the function of the unit in another outlet. Not all manufacturers use the proper wire gauge for the outlets required by the manufacturer and that can be an issue. You want 14 gauge wire minimum like # DW02408-1 for that particular...

    I can certainly help you determine what parts you need to add electric brakes to your 2015 Quicksilver 10.0 tent trailer. Based on my research, it looks like your trailer has a 2,000 pound axle. If that is the case you can use the following part numbers: Brake Mounting Flange - # 4-34 Brake Assemblies - # AKEBRK-2L left-hand side # AKEBRK-2R right-hand side Hub and Drums - # AKHD-545-2-EZ-2K for 5 on 4-1/2 inch wheel bolt pattern or # 8-173-16UC3 for 4 on 4 inch Breakaway Kit...

    I would certainly recommend the 1/2-inch wire loom # 459075-1. It will hold two jacketed 2 wire 10-gauge wire and three jacketed 2 wire 12-gauge wire. See pictures to the right. In addition, I was able to fit comfortably eleven individual 16-gauge wire # DW02359-1 into the 1/2-inch wire loom. I also took a digital caliper to measure the exact radius of each type of wire: 10-gauge is .17 of an inch, 12-gauge is .14 of an inch and 16-gauge is .09 of an inch. The 10, 12 and 16-gauge...
