Video Transcript for Review of Deka Wiring - 16-14 Gauge Butt Connectors - DW05744-5

Jeff Hello everybody this is Jeff at Today we're gonna take a look at the Deka blue butt connectors for the 16-14 gauge size wire and this is for a quantity of five connectors. Now these blue butt connectors will join two lengths of 16 gauge or 14 gauge sized wire and it will insulate the connection with the heat shrinkable nylon for adjustability and durability. Now the blue color on this will indicate the size wire this connector will fit. This one will fit the 16-14 gauge sized wire. And if you forget what color size fits what, it is also stamped on here.

16-14 AWG. Now to install the two wires, what you'll want to do is take your two wires that you're going to connect together and you'll strip off about a quarter of an inch of insulation on each end of the wire. Take your first wire, stick it into this end right here, and push it all the way until it stops. Basically there's a metal casing right there in the middle and in the very center is a little stopper. So when you push the wire in it'll stop and that should put that in the metal casing.

Once you make sure that the stripped portion is under the metal casing, take your crimper, crimp it all the way down until you make a good connection. And then you'll do the same with the second wire. Take the stripped end, stick it all the way in until it goes no further. Make sure it's under the metal or the stripped portion is under that metal casing. And then use your crimper and crimp that side down.

With both of them crimped, then what you'll wanna do is just tug on them, hold both wires and just tug on them. Make sure you have a good connection. Once that's good then what you'll do is get a heat source, like a heat gun, and then just apply heat over this insulation and it will cause this nylon insulation to shrink and it will completely seal around your connection and prevent the elements from causing a problem with your connection. Now this part is for a quantity of five connectors. We do also sell it as a single connector, its part number DWO5744-1.

Or as a ten pack which is part number DWO5744-10. But that should do it for the review on the Deka blue butt connectors for the 16-14 gauge size wire for a quantity of five..

The new axle we purchased from you is under this parade float. The float consists of a dedicated SUV and a heavily modified snowmobile trailer , the unique part is that it can bend in the middle to negotiate turns and the sail can be lowered to clear low obstacles on the parade route. This has been in parades in Seattle,Portland ,Calgary and Chicago .The art work changes every three years per parade rules. It takes about 6 hours to assemble the float at each parade and after, it all breaks down and stores in the trailer that forms the back half of the float.


Quality heat-shrink butt connectors. Easy to install with the right torch and one year later they are still working well.


I first learned of heat-shrink butt connectors in the aviation industry. I now use them for all of my automotive and outdoor wiring projects because they're designed to seal out moisture. Resultant splice is about as close as one can come to uncut wire using common shop tools.


made the trailer light installation very easy to install by removing the old light and install the new led light so using these butt connectors made it easy and painless. Also they were not badly priced so one stop shopping allowed me to order them with my new lights...



Everything is working perfect and thank you for the follow up. I will be buying more when the time comes that I need something you carry and I recommend you to all of my friends and colleagues,


I have found that the 16-14 Gauge Deka Heat aren't quite as good as their larger 12-10 Gauge counterparts. They still work very well, but the heat shrink shielding is a bit thinner and seems to split easier when making a crimp, and had experiences where the connecter wouldn't grab a 16-gauge wire on the first try. All total I've had an approximate 20% failure rate with this gauge connecter which I feel is a bit high considering their price point. I will use them again in wet use applications, but would like to see some improvements.

Brett F.


No additional failures once installed after one year.


Great, brand name products and some hard to find LED side marker lights. Refurbished an old EZ Loader boat trailer for carrying kayaks. Old incandescent lights were rotted off of the frame and the side marker lights in the fiberglass fenders were inside rubber grommets that were dry rotted. Etrailer had all the replacement lights, available in LED, and beat the price of any other option. Quality products. Delivered in 2 days under a free shipping promo. Etrailer is saved to my favorites for any trailer needs. Pic of the Yak project attached. New tail, fender and side marker LEDs!


I installed the pop and lock on my 2017 Honda Ridgeline. It was easy to install and it is wired to remotely open or use a key. It has worked without any issues. I'm very satisfied.

Juris R.


I wired the Pop &amp Lock to open remotely and it has worked every time. I used a different approach than what the Utube video had demonstrated.


My order was simple, some heat shrink and a few heat shrink butt connectors, no surprise that what I ordered is what was sent. The surprise I did get it how fast the order was processed and shipped. Shipping throughout the country right now is hit or miss- I’ve got an order from a major U.S. distributor for some simple tools, placed 2 weeks ago and still being “processed”...this order with etrailer was like 4 days, including a weekend, from when I clicked submit til it was in my mailbox. That’s outstanding! Thank you!


Quality products...excellent follow up to solve problems in shipping ,as a lens was cracked in box when I received email and pic to etrailer and replacement was in mailbox in two days!!!...small problem with license bracket LP10sb, very good quality for price but mount holes had to b redrilled higher to fit properly with light # STL9rb...overall great service and quality products ...about to order more parts after this review!!!...twisty


I would like to really thank the team at etrailer for making my order correct. George, Amy and Carol all worked well with communication with me when there was a small issue with the amount of connectors I ordered. They made things right and I have nothing but appreciation for their work and attention to detail to help me out. Thank you again and I will be doing business again!! A+


I purchased electronic trailer breaks for my camper. These breaks are an excellent product at a great price. The tutorials that etrailer offers are incredibly helpful and a superb resource. Their customer service is also spot on. When it comes time to work on my boat trailer I know where I'll be going for parts and/or help.


It’s just a satisfactory product. The vinyl shrink connector did shrunk after being heated but it didn’t shrink tight enough. Only time will tell if I will have corrosion in the connected wires when I start launching my jet ski trailer again. My jet ski and trailer has been stored since the pandemic.


Just received my order of new backing plate assemblies and some misc small parts. Ordered on line late Sunday night, confirmed I had ordered the right parts Monday morning before shipment went out. Customer service by phone was superb and the gal I talked with was perfect. Shipment was on my porch Friday afternoon. I did open box and inspect shipment that arrived completely intact/good shape and all looked good at this point. Not sure when will get to the brakes on the trailer but will post again when the job is done. So far nothing but good to say about Regards, John.


Order arrived very quickly. Placed on Friday, arrived on Tuesday from Mo to Pa. Items were packed well and arrived in good condition. Upon initial inspection all items appear of good quality. Ordered tires, brakes with backing plates, hubs ,seals and grease. Haven't installed any items yet, but I am sure I will have no issues. Free shipping is a plus. Additionally unlike other free shipping offers that are out on the back burner for a week, order was processed and shipped promptly. I have recommended etrailer to friends and would highly recommend them to anyone.


eTrailer is my go-to for boat trailer parts and I've always had a great experience using them. Everything works as anticipated. These connectors did the trick!


Lights are Bright and easy to install. I completed the job in 20min. The Deka Heat Shrink Butt Connectors made a nice water tight seal. Appreciate the prompt shipment of my order


etrailer has always been a pleasure to do business with. The products are easily found on the site. The product offering is broad. The information and videos about product application and use are terrific. Shipping is always on time. I have three trailers and shop here several times a year at etrailer.


Great customer service. Prices are good.


Had to buy an extra at local auto parts store. Could not get wires to stay in connector long enough to crimp properly.


Worked perfectly. I used them to wire in new LED boat trailer lights and wanted the shrink wrap effect to keep out water.


Does what it's supposed to, but pay attention to wire size when ordering, as some trailers have larger wires than 16014 gauge for their brakes


Good connectors and I haven't any problem with my trailer wiring. They have been on my trailer since 07/17.


Used these connectors for a lawnscaping trailer lights that sits outside. Shouldn't have any issues with weather. Easy installation and used a heat gun for the heat shrink ends.


All items were packaged great and arrived in excellent condition. Fast shipping and super service. Items will replace all of the existing brake components on my Casita trailer.


These are really nice and reduce the amount of time wrapping electrical tape around connectors.

  • Troubleshooting Running Lights that are Blinking When Turned On
    Whenever we see lighting issues it usually stems from a bad ground or a short somewhere. This can be the result of a bad 7-Way connector or wiring. Since you have exposed wires where you have done your splicing I highly recommend using some heat shrink butt connectors to get your wiring all sealed up properly. You can use part # DW05745-5 for the bigger 12-10 gauge wires and part # DW05744-5 for the smaller 16-14 gauge wires. These are heat shrink connectors which will seal around 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 Wiring Connectors for 14 to 16 Gauge Wires to Protect From Weather
    I have a solution for you, but the # 05731-5 are not heat shrink style butt connectors, so heating them isn't going to provide any protection. Instead I recommend using the Deka Heat Shrink Butt Connector - 16-14 Gauge - Nylon Insulation - Blue - Qty 5 # DW05744-5, which can be heated up to provide some insulation from the elements. This would be the best solution it sounds like and would be my recommendation.

  • Is a Breakaway Kit Required on an Old Trailer
    In order to determine if a breakaway system is required on your trailer you will need to contact your local DMV. This will vary from state to state. However, it is a good ideal to add a breakaway system regardless of your state's regulations as they will help to protect others on the road and your trailer in the event of an accident. Breakaway systems are relatively inexpensive and can easily be installed with minimal effort. I recommend the Hopkins Engager Push-To-Test Trailer Breakaway...

  • Best Option Installing the Wesbar 403075 Tail Light on a Jet Ski Trailer
    If your current light assembly is not a sealed unit, then you should be able to just replace the bulb as long as both bulbs are interchangeable. If the light assembly is a sealed unit, I would not recommend trying to change out the bulb. Breaking the seal could cause a risk of water contamination in the light when submerged. In this case, you can install the new light using heat shrink butt connectors, like the Deka # DW05744-5 in 14-16 gauge wire. Just cut off the plug and use the butt...

  • License Plate Light Compatibility with Tekonsha T-One Wiring Harness for 2018 Jeep Cherokee
    A relocated license plate bracket light will work with the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118605 you reference. You will simply splice into the brown running light wire after the converter box to get that running light signal. You most likely will need to ground the light to the bracket if it is metal or to the frame of your vehicle. I recommend using heat shrink butt connector like # DW05744-5 for that connection and weather seal.

That said, you could indeed simply remove them and hardwire the wires using butt connectors like part # DW05745-5 and part # DW05744-5.

    We do not offer a longer version of the Tekonsha Plug-In Wiring Adapter for Electric Brake Controllers part # 3040-P which is 32" long. The black 12 volt power wire and blue brake output wire are both 12 gauge so part # DW05745-5 is correct for these and the red stop light switch wire and white ground wire are both 16 gauge so part # DW05744-5 is correct for these.

  • How Long Are The Wires on the Hopkins HM11141144 Wiring Harness?
    The wires on the Hopkins wiring harness item # HM11141144 are 6" long. I recommend using butt connectors instead of splicing the wires together so you have plenty of room. I have linked an install video. You will need 2 different size butt connectors because there are both 12 gauge and 14 gauge wires in the harness. I recommend item # DW05744-5 for your 14 gauge and item # DW05745-5 for your 12 gauge wires.

  • Trailer Wiring Harness Installation on 2015 Acura MDX
    I'm sorry that happened. According to Tekonsha, they haven't changed the plug used on their 4 pole trailer connectors in many years, so I suppose it's possible that either the drain hole diameter might not be consistent across the vehicle line or there might be another larger opening in the floor pan. What I'd do in your situation is use a rotary tool like a Dremel to notch one edge of the hole just enough so you can slip the trailer connector through. Reinstall the plug using silicone...
