Hello everybody, this is Jeff at etrailer.com. Today we take a look at the Deka yellow butt connectors for the 12 to 10 gauge size wire. And this is for a quantity of 10 connectors. Now these yellow butt connectors will join two lengths of 12 gauge or 10 gauge size wire and they'll insulate the connection with this heat shrinkable nylon for adjustability and durability. The yellow color will indicate the size wire that this connector will fit which is the 12 to 10 gauge size. And if you're not sure or remember which color fits what it is also stamped on the connector itself 12 dash 10 AWG.
Now to install these connector it's pretty simple. All you have to do is take the two wires you're wanting to connect. And at the end of it, strip off about a quarter of vincent quarter inch of the insulation, so you have a bare wire on each end and then you'll take the first wire and you'll stick it all the way into this side and push it until it goes as far as it will right in there's this metal casing in the center here, right in the middle there's a stopper. So when you put your wire in, it'll stop automatically. So just push it in all the way make sure your strip portion is under that metal casing and then take your crimper and just push down on that to crimp that wire to that side.
And then you'll do the same with the second wire. Take the strip den slide it all the way into it'll go no further make sure it's under the metal casing, crimp that end. And then once they're both crimp what you probably want to do is pull on the wires to make sure you got a good connection. Once that's good, then what you'll do is take a heat source, like a heat gun and then just apply heat up and down along this nylon here and it'll shrink over the insulation to completely seal around the connection and it prevents the elements from getting into that connection to cause a problem. Once that's all done, you're all set.
It's all ready to go. Now this part is for a quantity of 10 connectors. We do also sell it in a single pack which is part number DW Oh five seven four five dash one. And we also sell it in a five pack which is part number DW Oh five seven four five dash five but that should do it for the review on the Deka yellow butt connectors for the 12 to 10 gauge size wire for a quantity of 10..

Excellent product, very durable, heavy duty looking, high quality. Not expensive and it comes with excellent instructions that are available on youtube on how to wire it to your truck. They give you so much details that anyone with proper tools can do it. Working with them was easy and enjoyable. They are knowledgable and professional to work with. Thank you eTrailer!
This part is a unique bundle etrailer has put together that is exactly what any Colorado/Canyon owner needs if their vehicle came without a tow package. The installation video was excellent and makes it possible for anyone to self install in their driveway.
Most pleased with the action taken regarding a slight issue with my original order. Well done!
Performs exactly as described and would highly recommend them for someone looking to give their trailer protection while operating during freezing temperatures. Easy to install and wire!
I had ordered a wiring harness but it didn't fit my truck,called etrailer got the right one on order ,and they emailed the return shipping label so I could send it back. These people are great to do business with, plus being very helpful in finding the right part.
Product worked as described.
connectors and breakers to hook up my brake controller arrived in order, installed easily, and lasted 1 year so far...
Ordered 3 parts: RM-156-25; RM-156-75 and DW05745-10. All received very quickly, as is the case when I purchase from etrailer. More importantly, I get a 'live person' when I call for assistance and the service rep. is always knowledgable ( not an answering service that "will have someone call back". Time was spent with me answering all my questions and providing suggestions and opinions when I as for them, related to my project. Great company, great service - keep up the great work!
I really like the idea of any outdoor wiring connector that has self-sealing heat shrink. I don’t agree with the suggestion of using a lighter to activate the heat shrink—use a proper heat gun designed for this.
Was a great recommendation buy etrailer.com in their installation video for my wiring harness. Glad I took their advice. Product was much cheaper than the local stores I looked at.
I changed my trailer brakes to electric the NEV-ER-ADJUST brakes are good quality as is the heat shrink butt splices, 12-2 cable for the brakes. Glad I purchased new seals as there easy to damage when removing Very satisfied Thanks
I had very little room between my spare tire and the socket. It's probably listed somewhere but I couldn't find it for the two I was looking at. I made an online inquiry and Michael H. got right back to me with all the dimensions and clearances needed, which convinced me to go with the HM48470. Ordered it, some wire and a receiver lock, which arrived today. Will wait for the snow to melt before I crawl under there to install them. Thanks again for the great service!
Order was complete and delivered in a timely manner. Only problem (minor) was the 7way pigtail was not wired to color code. Had to use test light to get 3 of the wires in correct location. Could be a problem if someone wasn't comfortable with ringing out wires.
Great website, easy to locate and order the right parts, fabulous delivery speed. Love eTrailer.com's videos to guide you through the installation -- THANKS!!
I agree with previous reviews that the packaging needs to improve. I had one brake assembly that had damage electric wires during shipping & I needed to repair. That is the only gripe I have. Other than that, THANKS!
The product arrived promptly as scheduled. The installation is simple: bolt the unit on the trailer frame with the supplied star washers and hook up the single power wire. The jack worked as advertised. Speed was typical for an electric jack.
The quality of the jack could be better. The three housing screws were pushed thru the plastic cover. Repaired by removing the screws and reinstalling with small washers. The fuse holder, which is already installed on the power wire below the housing, is not water proof, which should be for an exterior application. Time will tell if the unit is better than my initial observations.
Suggestion: the manual jack handle needs to be longer so it clears the top the of the propane tanks.
100% will and have ready reccomended etrailer!! I called because I truthfully had no idea what all I needed so I was hoping an expert would help me. My hold time was long, the recording told me approximately how long and it was accurate. Also, it's three weeks before the Fourth of July and everyone wants something to get road worthy. No big deal.
Once Geoffrey was on the phone I was absolutely blown away. He was patient, understood exactly what I was looking for (even though I didn't) and was incredibly helpful in the phone. He took his time to make sure we were going to have everything we needed to get the job done and get camping. He checked to make sure we were ordering the right size, even when our owners manual was super confusing he assisted in how to figure out exactly what we needed.
Shipping... Wow. We placed our order and less than 13 hours later it had been picked, packaged and was on its way to a shipping facility. We received it 2 days after placing the order at 7pm. We are close, but still, that's incredible!
Completely satisfied with every aspect of this experience.
Received all the parts to rebuild my travel trailer brakes in a short time. Everything from lug nuts, heat shrink splices, drums, bearings, seals, brake backing plates with complete brake assemblies. All in two boxes, albeit two heavy boxes... Total rebuild time from bare axles to tires on and torqued, about 2.5-3 hours. Everything I needed was there. Thanks to Sam G. for the great customer service.
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.
etrailer products and service are excellent! With their helpful videos and staff (plus a little help from Curt Manufacturing and our teardrop trailer manufacturer (CampInn)) I was able to install electric brakes on the trailer, and a controller in my vehicle by myself. I had never installed electric brakes before. Everything works perfectly!
The heat shrink butt connectors worked as advertised. Great Product.

All is well!
Same exact brand that was on my trailer. Easy replacement of the brakes. A full $50 cheaper than the exact ones at the dealer where I purchased the trailer. Very happy.

Aaron is top-notch! I will make sure he sees your review. Thank you so much!
Easy to use
Recommended for better moister protection on bare wire connections. Kits dont come with the heat shrink that this product has incorportated. I wanted to use a lighter for the heat shrink but found that the cheapest heat gun provided on this site works much better in the hard to reach areas.
Used to connect new 7 pin rv plug/cord to trailer.
Much better than standard butt splice from auto parts store.
