Video Transcript for Review of Deka Wiring - 12-10 Gauge Butt Connectors - DW05745-5

Hello everybody, this is Jeff with Today, we're gonna take a look at the Deka yellow butt connectors for 12-10 gauge size wire. This is for a quantity of five connectors. Now, these yellow butt connectors will join two lengths of 12-gauge or 10-gauge size wire. It will insulate the connection with the heat shrinkable nylon for adjustability and durability and the yellow color of this connector indicates the size wire the connector will fit which is 12 to 10 gauge size, and also if you don't remember the color, what size it fits, it is stamped on the connector, 12-10 AWG, which it's telling you. But basically when you install this, what you'll do is get your two wires and enough you'll strip about a quarter of an inch of insulation off the end of each wire that you're wanting to connect, and then what you'll do is insert the end of the one wire all the way in into the metal casing until it stops right in the very center, they do have a stopper, so you push the wire in there, once it stops you make sure it's in the metal casing there and then what you'll do is take your crimper and you'll just crimp down on that metal casing until it holds the wire in place, and then you'll take your second wire and do the same on the other side, slide it all the way in, the part that you've stripped off, slide that all the way in 'til it stops, make sure it's in the metal casing, take your crimper, crimp it all the way down.

Once your two wires are in there, what you might wanna do is pull on both wires just to make sure you do have a good connection, that they've been crimped correctly. If that's all fine, then what you'll do is you'll take a heat source like a heat gun and then just apply heat over the whole insulation and what'll happen is it'll cause this nylon insulation to heat to shrink and it'll completely seal around your connection and prevent the elements from causing any problem with your connection. Now this part is for a quantity of five connectors. We do also sell this in a single pack which is part #DW05745-1, and also as a ten-pack, part #DW05745-10. But that should do it for the review on the Deka yellow butt connectors for the 12-10 gauge size wire for a quantity of five..

Worked great 11 days to receive, E trailer should not use USPS for delivery.


The products were ordered on Sunday night late, delivered by Wednesday. Converting drum surge brakes to disc, electric over hydraulic on a boat trailer for 26ft Sea Ray boat. I had everything including Titan brake actuator, 4 kodiac rotor and caliper conversion kits with bearings, and new lines installed by Thursday evening. Installation was straight forward, everything fit perfectly. One of the calipers was malfunctioning (not releasing). I called customer service and I had a new one within two days, it's now installed and working great!! Great product! Awesome service!!


My parts arrived on time. The shipping was very prompt.
The parts ordered were all there and looked good. Haven't installed the brakes yet, as I have to weld on flanges first. Also I have to replace the SS sleeves that the seals runs on with a slightly larger one, as the new seals are larger.
I may send you a picture with the new flanges and SS sleeves in place, when I'm done.
Thank you for the great service.



These brakes were installed on a boat trailer, which is not used very often. The brakes are working fine.


all the wiring products worked out great .all new connections from the truck to the trailer and the lights are a lot brighter now .new brakes next.

Ron G.


had no problems all the parts are working fine


Made a firm connection and shrunk down to seal up the wire nicely. While these connectors are a little on the pricy side, I think they are well worth it for any wire connections that will be exposed to the elements.

Brett F.


It’s been a year and the connections are still working without fail.


Use these for a weathertite connection. These are well worth the money to prevent electrical problems from corroded connectors.



I have never regretted using the weather proof electrical connection, because the heat shrink tubing ensures a tight, dry seal. Absolutely no problems electrically.


All wire kits and connectors worked well and made for a quick install



Works great, no problems


Did what they were supposed to do.


The right tool for the job. I used the heat shrink butt connectors to install a DYI trailer hitch wiring harness for my '15 Chevy Colorado. They worked great and are keeping my wires dust, dirt, and most importantly - water - free. Thanks etrailer!


I found a how-to video from etrailer online. Without the video, I would have had to pay someone to install (more for the wiring). Went directly to etrailer to buy the hitch for my Jeep. Very satisfied and very grateful for the service-


I basically ordered enough parts to replace the eitire magnetic brake / hub assembly on two (2) 3500# Dexter Axles after I replaced the bent axles that were underneath my 2011 Surveyor SP280 Travel Trailer. It turned out to be a better deal to replace the assemblies rather than rebuild / resurface what I had.
The parts that I ordered arrived quickly but were a little scuffed up due to the packaging materials used but in general the parts were not severely damaged.
The fit of the parts has been very good and to this point I am satisfied with the purchase. I suppose "the rest of the story" will be told when we go camping for the first time and see how the parts perform when "the rubber hits the highway".


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.


Great quality connectors, and heat shrink insulators worked great.


This is a standard Heat Shrink Connector. The clamp type connectors would be a better choice for connecting brake wiring.







This 7pin RV side fit my 2018 View perfectly. Factory plug had the ground wire not connected. This product allowed me to butt splice the ground wire to the new wiring and complete a trip. Thanks to Bryon for helping verify fitment and fast service. All is working right now.


Excellent products, shipped as promised and arrived on time. I have installed all the products. Although it took me longer then a professional installer, I had little to no issues. The online installation videos for all the parts (which were attached to the online order status sheet) made it extremely easy to install. The videos were of a professional actually installing the equipment step by step. has a customer for life.


Good heat shrink connector. Makes for watertight connection.


The parts and service I received from etrailer exceeded my expectations. I am a very satisfied customer that with gladly return in the future. My thanks go out o the entire etrailer team!


Changed horse trailer brake assemblies and wiring all fit perfect. No problems at all!!!! Great service! Thanks.


I ordered this controller and additional parts from Laser. Before committing to buying, I asked him many questions. He answered them all in about a clear and concise way as possible while presenting a picture of how to install the device. It arrived today and I haven't started, but he also emphasized that I could call if I ran into any difficulties. I'll follow up when the job is complete. My experience in this context could not have been better.


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


Used these when putting a wirer harness on my truck to make wire connections


I've used your site several times for my boat trailer needs ,everything is always delivered within a few days of placing my order. The tutorial videos help with details when I need a reference


Worked great to install the trailer connector on our Chevy Colorado. Shipping was fast, had the order in 2 days!

  • Troubleshooting Boat Trailer Where All Lights Stopped Working
    Since the connector on your vehicle is functioning properly you are correct in assuming that it is likely a ground issue causing your lights to no longer work. There should also be a main ground on the tongue of the trailer as you mentioned. I recommend seeing where the white wire comes out of the frame, and looking for any loose ground connections. I also recommend cutting the white wire before it goes into the frame and adding a length of # 12-1-1 with a ring terminal # 44-5310A to ground...

  • Availability of Extension To Relocate 7-way Trailer Connector
    We don't offer a dedicated extension, but I have a couple of alternatives that can be used to do that for you. The least expensive option would be to use a 4-foot pigtail like # HM40985, but you'd need to cut off the factory round US CAR connector that's currently plugged into the rear of your 7-way and wire in the pigtail. The wire color function is shown on the linked product page. I'd recommend using heat shrink butt connectors like # DW05745-5 to protect the connections from moisture. An...

  • Parts Needed to Add Brake Controller to 2015 Infiniti QX70
    It sounds like you're pretty well set up! I'd recommend the Curt Echo wireless brake controller, part # C51180. The Echo communicates wirelessly with your smart phone, allowing you to control and monitor the performance of your trailer brakes from the vehicle cab whiteout needing extensive wiring and drilling any holes in your dashboard. All you'll need to do is install the # HM11140805 and plug the # HM47180 into it. Ground the white tire to the vehicle. The red wire would be extended...

    I have another option for you, but the Trailer Idler Hub for 2K E-Z Lube Axles # AKIHUB-545-2-LFEZ-2K you were looking at are not designed to be used with brakes. Since your spindle uses inner and outer bearing # L44649 the only hub and drum assembly that will fit is the Trailer Hub and Drum Assembly - 2K E-Z Lube Axles - 7" - 5 on 4-1/2 - L44649 - Pre-Greased # AKHD-545-2-EZ-2K which is only compatible with wheels up to 12" in diameter, and would use Electric Trailer Brake Kit - 7" #...

  • Recommended Electric Trailer Brakes For Dolittle 6x12 Cargo Trailer With 2990lb GVWR
    We do not have a kit with all of the components needed to add electric trailer brakes to your Dolittle 6' x 12' cargo trailer but I would be happy to recommend the products needed. Since your trailer has a GVWR of 2990lbs it more than likely has 3500lb axles but you will want to check the axle tag located on the center of the axle to be sure. First you will want to make sure that there is a brake mounting flange installed on the axle. This is a 4-bolt flange that will be located directly...

  • Can I Install a Tekonsha Primus IQ Brake Controler on 2018 Jeep JKU
    Yes. The Tekonsha Primus IQ # TK90160 is compatible with your 2018 Jeep JKU, but there are no available adapters to make it an easy plug and play installation so you will need to hard wire it into your vehicle. I've linked the installation of a similar Tekonsha brake controller for you to use as a guide during installation, since the process will be identical. You will use some of the wiring that you've run when installing your 4/7 way connector during this process, but you'll also need...

  • Converter To Provide Separate Brake And Turn Signals Functions On Trailer From A Standard 4 Pole
    On standard trailer wiring the right and left wires run as a combined signal. So the brake and turn signal for one side will be combined and the bulb itself acts as a brake and turn signal depending on the signal current. Since you are wanting to use separate brake and turn signals from a standard combined wired 4 pole plug you are going to need the Vehicle to Vehicle Tail Light Converter Item # 118158 as well as the 4-Way Wishbone Trailer Wiring Harness with 42" Ground Wire - 40' Long...

  • Troubleshooting Trailer Wiring for Fleetwood Pop-Up Trailer and 2003 Mazda B3000 Pickup
    A potential cause for your issue is a weak ground connection. Trace the white ground wire from your 4-pole back to where it attaches to the vehicle frame. This ground must be secured to a clean and rust-free spot on the frame. If necessary sand off the rust/dirt from that grounding point and reattach the white ground wire or relocate it a new spot. If this does not correct the problem then I suggest you next test your existing 4-pole trailer connector on your Mazda to confirm it is functioning....

  • Parts Needed to Add Brakes to 2000-lbs Axle on Fleetwood Pop-Up Camper
    We've got the parts you're looking for! You will need to swap the hubs for a hub and drum assembly; based off the spindle measurements it looks like you've got a 2000-lbs axle, so you'll want to start with the Dexter Trailer Hub and Drum Assembly for 2,000-lb Axles - 7" - 5 on 4-1/2 # 8-257-5UC3 for the hub and drums. These do have the 5 on 4-1/2 bolt pattern to match your current wheels. The caveat is that this is the only drum available to fit your spindle but it looks like (based off...

  • Troubleshooting Trailer Brakes Not Engaging But Brake Controller Is Working
    Since you are confident that the issue is not with the brake controller itself, I recommend starting by checking that the connector on the trailer does not have debris or corrosion in it causing the brake output signal to not make its way to the trailer's brakes. If the connector checks out, you will need to check the brake output wire coming from the 7-way connector to the brake assemblies for any damage or loose connections. If you find any damage, you will need to replace that section...

    The MaxxFan Deluxe 12V Roof Vent # MA00-06200K will do a great job of moving air through your truck topper since it outputs a healthy 900-cubic-feet-per-minute (CFM) air flow. This vent should be able to cool effectively in your topper well below its maximum speed capacity which should mean quiet operation a long working lifespan.

  • Recommended Wire Gauge for Installing Breakaway Battery Kit
    We typically recommend going with 10 Gauge Wire # 10-1-1 and Butt Connectors # DW05745-5 for the battery 12V power just to allow as much power to "flow" through it as possible. That's what I recommend using for the installation of your Tekonsha Breakaway Battery Kit # 20020. You won't need to place a fuse or a circuit breaker on your trailer side of things.

  • Is There a Brake Controller Plug On a 2011 Chevrolet Silverado 1500
    The 2011 Chevrolet Silverado 1500 does not have a brake controller plug under the dash nor do any of them from this generation. However, it will have all the wires ran for you which is almost just as easy as using a plug because there are only four wire connections that need to be made. The Tekonsha Primus IQ Trailer Brake Controller part # TK90160 is an excellent option and one of my personal favorites. The only other items you will need to install this brake controller are butt connectors,...

    Since the trailer is working just fine with your buddy's pickup, we know that the problem is isolated to your 2007 Dodge Ram 2500. What it sounds like to me is that you have a bad ground or some corrosion in the 7-Way connector on your pickup. Take a look at your 7-Way and clean out any debris or corrosion for starters. Once that is done it is beneficial to add some dielectric grease like part # 11755 to help protect against that happening again. If the problem still persists after that...

  • 7-Way Wiring Harness for 2015 Ford F-150
    There is a simple solution for you, but there is no trick to getting the wires of the # 118283 back out since the wires are different gauges due to the brown wire being for the right turn/stop functions and the blue wire being for the trailer brakes. What you can do is cut off the 7-way on the # 118283 and replace it with 7-way connector # HM47210 that has a pigtail; you'll only need butt connectors # DW05745-5 and # DW05744-5 to connect your splices.

    It sounds like you are looking for the wiring harness portion of the Hopkins Endurance Multi-Tow 4-Way Flat to 7-Way RV Trailer Adapter part # HM47180. If that is the case then this part is not available separately but you can obtain something similar with the Pollak Wiring Harness Extension part # PK11-934 and the Quick Fix 4 Pole Flat Trailer End part # HMC20031. If you need butt connectors to finish up your connections you can use part # DW05745-5.

    As you already have the 7 Way on your vehicle, you are most of the way there.

In-Line Circuit Breaker # 38630, and some wiring, # 10-2-1. 20 feet of wiring should give some excess if needed, and you may need some butt connectors, like the Deka # DW05745-5, if you do not already have any.

    I am sorry to hear you are having a problem with the Curt T-Connector Vehicle Wiring Harness # C56331 on your 2014 Dodge Grand Caravan. Since you are not getting power, I recommend first checking that the black wire that was run to the positive terminal over your vehicle's battery is securely connected to the battery terminal, and the fuse is fully inserted. Next check that this wire did not get pinched or burnt causing the power loss. If the wire was damaged in any areas, you will need...

    You've done a great job troubleshooting so far. Since you've ruled out the trailer and have replaced the brake controller, the issue has to be somewhere in the truck itself. You will need to sever the blue wire going into the brake controller approximately 6" back from the brake controller to test the output there. If there is a short somewhere on the blue wire, probing the wire without cutting it will not give an accurate reading. The best solution may be to replace the blue electric...
