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. .

Average Customer Rating:  4.8 out of 5 stars   (174 Customer Reviews)

This wiring has held up phenomenally over the past year of installation. I have been underneath the vehicle changing parts and have inspected the insulation jacket while there. Everything looks as good as the day I installed it after a full year of use in Central New York weather. Would highly recommend.


Comments
Two years in and the wiring has been switched through three different vehicles and still holding up phenomenally! It was really worth its weight!

The wire was awesome to use to wire my trailer tail lights with.


Comments
The wire was installed on a 1960 TourAHome and is working well under the trailer, I have not noticed any weathering of the wiring jacket. I still have some in stock for future use.

Used this wire to go from front of vehicle to rear, one conductor for the 12-Volt power, the other for the electric brake control.

I use one wire for 12-Vdc and do not use the second wire in the cable. I am using the Curt 7-way Bluetooth controller instead of a cabin mounted controller.

etrailer has been my “go to” for a few years now. Communication is always a top priority and their customer service is second to none! Regarding this Echo, I use it all the time when pulling with our 2019 Subaru Accent and often use it on other vehicles that have older/delayed brake controllers.

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.

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.

by:

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

The right wire, wired right makes for Very Right Stopping... I'm very Allrrrighty!!!



- 12-2-1
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.



- 12-2-1
by:

I am very happy with the items I received, everything went together with ease. This was the first time I attempted installing brakes on a trailer, your videos made it very easy to choose the items I needed and assembling. I will recommend etrailer to my friends in the future. Thank you John C.

Ask the Experts about this Deka Accessories and Parts

  • 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.

  • Will 30 Feet of # 12-2-1 Deka Wire be One Wire
    When you order 30 feet of # 12-2-1 we cut it to length in our own warehouse so it's going to be one 30 foot wire and not several shorter wires cut into pieces.

  • 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.

  • 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.

  • 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 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...

  • 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...

  • 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 # PT89ZR. I'd then check the magnet itself. I've attached an article to assist. If everything there checks out, I'd check the bearings...

    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...

  • 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...

  • How to Repair Sheared Brake Wires on Magnet of AxleTek 10 Brake Assembly
    As long as there is still a bit of wire still attached to the brake magnet on your # AKEBRK-35-SA, you can use a butt connector like the Deka Heat Shrink Butt Connector # DW05745-5 to connect a jumper wire from the sheared off end to the brake wire on your trailer. Brake wires are typically 12 gauge wire and if you need a jacketed 12 gauge 2 wire you can use the # 12-2-1 which is sold by the foot and has the positive and negative wire jacketed together.

    Yes, the HydraStar Disc Brake Kit w/ Actuator for Triple Axle Trailers - 13" Hub/Rotor - 8 on 6-1/2 - 7K Item # HSE7K-TR1 is a complete kit for swapping the brake components. Since the current bearing grease has to be removed during instillation the new bearing need to be packed.

  • Parts Needed To Install 7 Way Plug on Trailer
    Since a 4 way connection does not provide you with the capabilities to control the trailer's brakes, you would need to convert your boat's 4 way connector into a 7 way using something like the Epicord # 277-000143. In order to make wiring a bit easier and more organized, I also recommend using a Junction Box like the # 38656 so that you can connect all of the trailer wires to the box and then neatly wire the Epicord to the box. This will help ensure that all of your wiring is cleanly installed...

  • Recommended Air Distribution Box for Advent Air ACM135
    When it comes to roof top air conditioners, the air distribution boxes that are compatible with them are going to be fairly specific. The Advent # ACM135 is compatible with only 2 specific air distribution boxes: the Air Distribution Box and Thermostat # ACRG15 or the Air Distribution Box with Built in Thermostat # ACDB , so you would need to use one of those. You may also need some 12 gauge double wire # 12-2-1 and Heat Shrink Butt Connectors # DW05745-5 to complete the installation.

    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.

For the license plate light you would want to use the Optronics LED License Plate Bracket Light # LPL56CB.

  • Adding Interior and Exterior Work Lights to Livestock Trailer
    Considering how you'll likely be using this, if you don't already have an auxilliary battery on your trailer, you'll need to add one. You'll want a 12v battery, which can be sourced from a number of different places, but I recommend something that can at least handle around 50 amp hours. This eliminates the chance that you run your vehicle battery down and get stranded somewhere, in addition to straining that battery and creating the need for replacing it much sooner than you normally would...

  • 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....

This is pretty comparable, maybe slightly less, in weight compared to a traditional axle and leaf spring suspension. If you ever want to add electric brakes to this kit, I suggest picking up the following parts: Brakes - # AKEBRK-35-SA qty 1 Drums - # AKHD-545-35-EZ-K qty 2 7-Way Wiring Kit (If you need wiring for brakes) - # e99011 qty 1 Brake...

    I have a solution for you, but the Curt Echo Mobile Brake Controller # C51180 requires 7 way connectors on both the vehicle and the trailer to be used. I recommend using the Hopkins # H20044 and a junction box like the # 3375601101, which has color coded terminals to make wiring a breeze. This Hopkins connector will be compatible with both the Curt Echo and the 7 way on your truck if you need to tow without the use of the brakes.

  • 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...

These are self-adjusting brakes so there is no need for manual adjustments after the initial installation.

  • 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,...

  • 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.
