Video Transcript for Review of Deka Wiring - 16-14 Gauge Butt Connectors - DW05744-10

Hello everybody. This is [email protected] Today, we'll take a look at the DECA blue butt connectors, for the 16 to 14 gauge size wire. It is for a quantity of 10. Now, these blue butt connectors will join two lengths, of 16 gauge or 14 gauge size wire, and they'll insulate the connection with the heat Shrinkable nylon, for adjustability and durability. Now, the blue color will indicate the size wire that this connector will fit, which is the 16 to 14 gauge size.

And if you don't remember what size the color is, you can just look on them and they're stamped on there, 16 to 14 AWG. Now, to install your wires in this, What you'll do is, get your two wires you want to connect, and you'll strip off about a quarter of an inch of the insulation on each end, and you'll take the first wire, and you'll slide it into the tubing, all the way until it won't go any further. Basically, there's this metal casing in the middle, and right in the center is a stopper. So when you push the wire in, it'll hit that and stop, so then you just make sure your stripped wire is underneath the metal casing. Take your crimper, crimp down on that metal casing, to make your connection.

And then, you'll do the same for the second wire on the other side, take the strip, then push it all the way until it'll go no further, make sure it's under the metal casing, take your crimper, crimp down on it, and then they'll both be crimped. And then, what you'll want to do is probably grab each wire, and just pull on both of them or just tug on it slightly, to make sure you have a nice, good connection. Once that's all done, you have a good connection, then you'll take a heat source, like a heat gun and then you just apply heat over this whole installation, and that'll cause this heat shrink insulation to completely shrink and seal around the connection, and prevent the elements from causing any problem with your wire connection. Now, this part number is for a quantity of 10 connectors. We do also sell this in a single piece, which is part number DW05744-1, and a five-pack, which is part number DW05744-5.

But that should do it, for the review on the DECA blue butt connectors, for the 16 to 14 gauge size wire for a quantity of 10..

Average Customer Rating:  4.8 out of 5 stars   (359 Customer Reviews)

This blue butt connector joins two lengths of 16-14 gauge wire. Insulated with heat-shrinkable nylon for adjustability and durability.


My order was delivered quickly. Everything looks in order, but the packaging leaves a lot to be desired. The thin cardboard box was crushed in two corners. The interior packaging seems to have protected the contents but I'm not sure that it would be useable if I needed to return the product. An exterior box with air cushions was needed.


I used these on one of my trailers the day I got them. They worked great!


I want to thank you for all your help with my trailer you were more helpful than you realize. So this is my trailer for a 22' Flats Cat shallow draft Catamaran. I totally dismantled my trailer and buffed by hand with a wire buffer and sand blasted in some spots and applied multiple coats of some very expensive galvanize paint (Z.R.C.). I installed all new C. E. Smith Carpet (about 80'), seven new LED waterproof lights, new springs, new equalizers, new tongue jack, new wench, new safety chain, new chain brackets, all new SS hardware and a 35' long wiring harness.
I was able to send only one review with a picture of the safety chain and brackets. I'm having a little trouble with the rest..oh some of these items were bought locally or from your competitors, until I found ETRAILER. Your prices were cheaper for the exact same things. Your helpful how to videos were helpful. And Rose, your personal helpful knowledge made my buying experience very pleasant, I actually enjoyed talking to you! Thanks to ETRAILER and specifically to Rose G.


Considering the package was a disaster when it arrived and many pieces missing I am not a happy customer. Only two of this item was received and not in a package of 10 as ordered. Two, two separate tossed into the open box.

I am sorry to hear that your experience with us has been less than easy and efficient. I will pass this along to our customer service team and get you those missing connectors as soon as we can.

Just upgraded to a 2016 Odyssey and need to tow my camper.
Purchased the OEM hitch and OEM custom harness (from car to 4 pin on hitch. OEM Hitch comes with nice beefy flange where the 4 pin connector mounts. But I needed a 7 pin for electric brakes and bought this ETBC7 kit to do the job.

I ended up cutting a custom hole in the bumper cover and figuring a way to mount the bracket in this kit directly to the OEM hitch. Wanted to share photos of the install for anyone else in the same boat. Advantage of my install is that the 7 pin is mounted above the bracket, protecting it from injury from low clearance obstacles on the road. One Con, is I had to mount it upside down so it didn't interfere with the metal bumper under the bumper cover.

One issue I remember is that the Ground wire on the 7 pin harness didn't come close to reaching an available frame member, at the side of the car. I had to cut off the ring lug and extend it out to the edge of the car to complete the install. But it is done now!


Didn’t end up needing these but I have no reason to not rate them 5


Look great so far


Worked very well on a trailer tongue replacement rewire.


I don't usually do product reviews but wanted to post this one. This was my first purchase from etrailer. I purchased all four brake assemblies for our 5th wheel which I felt was the easiest and best way to go and had my drums machined. It was a very easy transaction, the parts came quickly and fit as they should. Very pleased with the product although I have not put the trailer on the road yet.
BUT- The packaging was very poor. The assemblies were in a carton twice as big as it needed to be without adequate packing and the items rattled around to the point that two shoes were knocked out of place on the backing plates. I was able to correct it and no damage done, this time. Please improve your packaging.
I would definitely buy from etrailer again.

all good, over 6000 mi and no problems. thanks

With the instructions provided, a left handed monkey could hook it up. Works perfectly


Have to have a helper ride in tow vehicle to adjust the sensitivity to match the RV breaking force. Example, you don’t want the tow vehicle trying to stop your RV. Just want it to stop it’s own forward motion. Once that’s done it’s ready to tow with no worries. Had 2 radio remote braking systems fail us which is why we went with the permanent one that’s wired up to RV.


I purchased a 5th wheel wiring harness and heat shrink butt connectors,
for my 2015 GMC Sierra. I installed a tail gate light bar and did not want to cut the factory wiring. With the harness I was able to plug into the factory trailing plug
and butt connect to the light bar, while still being able to use both the 7 blade and flat trailer connectors. It made for a easy and very clean connection. thank you to
Steve and the E trailer web site for helping make this a easy job.


Was sent the splices by etrailer to replace the ones sent in the Factory Kit, They are more heavy duty and resistant to wet climates. The Reps at etailer always make every effort to help the customer.

Durable & Great

High quality parts, expert guidance from eTrailer, competetive pricing!


I bought these based on an installation video on etrailer for RVST50 (trailer brake/signal lights). In the video they used these. They are for 16-14 gauge wire. The wiring in the lights is 18 gauge. I’m not an expert, wasn’t sure if I could use them, so I just ended up going to Home Depot and getting the correct size. The product itself is as described.


Being a new boat owner I was quickly overwhelmed by what I didn't know. Re-wiring, re-lighting my trailer was my first project. etrailer has a wide range of products, but most important to me, was their added product information and instructional information which helped me make the right selections to get this done. Add to that is their very competitive prices. etrailer will be my go to source for my future trailer needs.


Received my towbar, Airforce One and lighting kit in less than a week! Great videos and knowledgeable people, can't wait to get everything installed this week and get on the road. Thanks Susan and George for such a wonderful experience.


I wish I found these sooner, great for rewiring trailers and old vehicles too!

Still solid. No issues!
Gregory - 04/23/2020


Everything arrived in good condition. Only thing that could have been better for me would have been installation instruction sheet. I was able to get that information from the web site. Have bought from etrailer before and never have had problems.

worked fine
Edward S - 08/23/2016


I like them.


I thought it took a little more heat than they should to melt. Other than they work fine.


I found etrailer a few weeks ago while searching for items to repair my boat trailer. Since then, I've made 4 or so purchases from them. Each transaction was perfect and stress-free. They respond promptly with emails updating the progress of the transaction, respond quickly to any email inquiries, ship almost immediately, and follow up after delivery. I've since recommended etrailer to friends who have the need for their service. It's a pleasant surprise to stumble across an awesome internet site such as etrailer, where reasonable prices and customer satisfaction are important to them.


Easy install, nice quality set up.


Used these to install led lights all around boat trailer. They made installation a breeze and a year later no issues. Only regret is that I did not install led lights years ago.


I like the concept of these connectors, but they have a few faults.
1. They don't seem to be a "standard" size. When crimped with my Triplite ratcheting crimp tool, they don't always crimp all the way. I had to move to the next smaller die, and that mashed the tubing a lot.
2. Even when using the correct Die, the tubing seemed to be significantly damaged during crimping. It made me wonder if the moisture proof nature was compromised.

I think I'll just go with standard crimps, and put a piece of heat shrink over the connection. I know it is a extra work, but these don't impress me.
etrailer is great though. great prices and service.

  • Can I Wire My Backup Camera System into the Vehicle's 7 Way Trailer Plug
    There isn't a specific product for this application but you could splice into your trailer wiring harness to provide power for your backup camera. The best solution for you on this is going to be to splice into the running light circuit on the 7 way connector, so that all you'll have to do is turn the lights on the truck on in order to activate the camera; using the 12v aux circuit would draw power from the battery constantly and likely drain the battery. The running light/tail light circuit...

  • Troubleshooting Trailer Wiring Without Typical Color Wiring for Lights
    As you noted, the typically wiring colors for a 4-Way connector is white for ground, brown for tail/running, yellow for left stop/turn, and green for right stop/turn. The confusing part is that even though this is the typical way that the wiring is configured, not everybody uses the same color schemes. It sounds like either your F-150 or your trailer has different wiring colors than what we just talked about so you will simply need to use a circuit tester like part # 40376 to verify the...

    The Jensen RV Stero part # JWM10A that you referenced requires around a 11" wide x 3" tall cutout which is fairly standard for single din stereos so there should not be much issue here. In regards to wiring, you will need to remove the pigtail you have used to install the Jensen RV Stero JCD3007 and replace this with the one that comes with the above using butt connectors part # DW05744-10 and part # DW05744-5.

You would install the white wire to white wire, brown wire to black wire on each tail light, green wire to red wire on the right side light, and...

  • Reasoning To Reinstall T-Connector that Has Sides Reversed
    I was able to pull up your order to see you have the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector C56150 which has since been discontinued. Connecting the green side of this T-connector to the drivers side tail light won't effect the stop light function on your trailer, but will reverse the turn signal functions on your trailer.

    Your Tekonsha Prodigy P2 Trailer Brake Controller # 90885 thinks there's a short somewhere in the wiring. My first recommendation is to check the ground, as this is usually the cause of nearly all wiring issues. Ensure that you have a proper ground (i.e touching bare metal). Next would be to check all the connections to ensure there isn't any loose wires that could potentially be touching and pulling apart and then touching again, giving you the "S.H" error code.

    To install a 4-pole connector at the rear of your 5th wheel, the easiest option would be to tap a 4 pole vehicle end harness like # 18002 into the taillight circuits of the fifth wheel. In most states towing a trailer behind another trailer is illegal in many states, and we do not recommend doing it for safety reasons. You will also need to determine if your 2018 Ford F-250 Super Duty's tow package has a sufficient rating to handle the draw of the lights on both the fifth wheel plus the...

  • Wire Gauge Used for Low Profile RV Combination Tail Light # RVSTL61
    I went out to the warehouse and used our wire gauge measuring tool to measure the wiring on Low Profile RV Combination Tail Light # RVSTL61. It falls between 16 and 18 gauge wire so at the tightly wound ends it would measure a little smaller. So in other words 16 gauge. For heat shrink butt connectors for 16-14 gauge wire we have # DW05744-10 for a 10 pack and # DW05744-5 for a 5 pack.

  • Recommended Wire Gauge to Wire 8 Marker Lights and 2 Taillights on a Homemade Camper
    You can use 14 or 16 gauge wire for your marker and tail lights on your camper. I recommend using the Deka 14 gauge jacket wire # DW04923-1 because it's insulated for abrasion and chemical resistance. Having more marker lights means more draw on your circuit, and the reason I would go with the 14 gauge wire is because it can handle more amp draw. You also may need heat shrink butt connectors like # DW05744-10 to join lengths together. I included an installation video and video review...

  • Do Boat Trailer Wiring Connections Need to Be Waterproof
    Ideally, you'd unplug the trailer before backing into the water but you'll be a lot happier in the long run if you'd solder your connections and use heat shrink tubing like part # DW05451 followed by some electrical tape. If you don't solder, you can use heat shrink butt connectors like # DW05744-10 followed up with some electrical tape.

    You would need a larger size heat shrink butt connector to fit two 14 gauge wires together in one end. The largest we have are for 10 to 12 gauge wire, # DW05745-10, and that size would likely work. There isn't a specific gauge wire used for the color of the insulation around the wire.

But in a 4-Wire set up on a trailer where the functions are running lights, turn signals/brake lights, and ground...

    That is an excellent question and is asked more often than you think. Electric brakes like what come in the Electric Trailer Brake Kit # AKEBRK-2 can be submerged in water when you are loading/unloading your boat. Since water and electricity don't play nice together you do need to disconnect the wiring to your tow vehicle before backing into the water.
