Video Transcript for Review of Deka 3/8 Ring Terminal - DW05705-1

Michael: Hi there, I'm Michael with Today, we're going to take a very quick look at this Deka ring terminal. This ring terminal is going to allow you to easily connect your wires to a stud, so like on a battery or something like that where you need a nice solid connection. This does allow you to crimp the vinyl installation down onto your exposed wire. This is going to have an internal diameter right about 3/8 of an inch. So it's going to be good for your 3/8 inch diameter studs, will fit right up in there.

This is going to work for your 12 and 10 gauge wires, will fit right in there, allow you to crimp down on them and give you that nice secure connection to attach to your stud. That's going to complete our look at the Deka ring terminal. Again, I'm Michael with, thanks for watching.

I just purchased a Ranger Bass boat and the wiring is very old and the lights don't work. I found everything that I needed to completely replace and install new wiring and lights. This is a very good website to find and get exactly what I needed. I would highly recommend that people shop this site for all their trailer wiring needs.


Worked great


connectors and breakers to hook up my brake controller arrived in order, installed easily, and lasted 1 year so far...

  • Both Turn Signals Flash at The Same Time
    The cause of both turn signal lights flashing together would almost certainly be attributed to a poor ground. There are several grounds you will want to check which include one for each light, the trailer side trailer connector and the vehicle side trailer connector. One of these locations will more than likely contain the problem you are experiencing. It is important to make sure each ground is attached to a bare metal surface. It may be necessary to undo the ground wire and then use some...

  • Can 7-Way of Electric Trailer Jack be Cut Off and the Wiring Run to Trailer Battery
    If your electric trailer jack has a 7-Way built-into it for power, like the Buyers Products # 3370093500, then it is completely acceptable for you to cut off the 7-Way and run the power to the positive terminal on your 12V battery. Instead of running your ground to the negative terminal on your battery though I highly recommend grounding it to the frame on your trailer. This will be a much better ground option that running it to the battery. You do want to check and make sure that your...

    The third cable you mentioned for the Truck Bed Cargo Camera # 3460010 will indeed plug in between the camera and module cables also included with the kit. The red and black leads are for the camera's power and ground. The module also includes extended leads for power and ground. I have labeled the picture you attached accordingly. The ground leads (black) from the module and camera need to be attached to a bare metal surface using ring terminals like # DW05705-1 and a screw. The...

  • Tips for Getting a Large Trailer Wire to Fit into a Small 7-Way
    If you are having a hard time getting the connector wires from your trailer into the replacement 7-way that you have there are a couple things you can try. The first thing I would try would be to twist the end of the exposed wire until it will not twist anymore. This will make the wire as skinny as possible and give it the best chance at fitting in the slots. Or you could use ring terminals like our part # DW05705-1 to attach to the wire, and then attach the ring terminal to the 7-way....

  • Grounding Trailer Lights That are Mounted to Wood Rather than Metal
    If the lights you are using have wires coming out of the back like the Optronics Camping Travel Trailer Stop, Turn, Tail and Back-Up Light, part # RVST56, then you can simply connect an extension wire like part # DW02359-1 from the ground wire on the light to the trailer frame and ground the white wire from your trailer connector to the trailer tongue. If the lights you are using ground through the mounting hardware, then you can simply run a jumper wire from the post on the light that...

  • Using Battery Charger Included With HM39530 Brake Buddy When Negative Battery Cable is Disconnected
    We've got a solution for you. You'll want to use a Deka Quick Disconnect Battery Terminal, part # DW05312. On the terminal end that remains on the battery once disconnected, you'll attach the ground wire for the charger using a # DW05705-1 ring terminal. This leaves the charger grounded once the negative battery terminal is disconnected. I've provided a photo showing where to place the ring terminal.

  • Power To Brake Controller and Trailer Connector on a 2006 Chevy Silverado 2500 Cut Out
    The power for the brake controller and trailer connector on your 2006 Chevrolet Silverado 2500HD is feed from two studs on the power distribution center (PDC) which is located under your hood, in the engine bay. The only thing that I can think of as to why both the power for the brake controller and trailer connector suddenly went out assuming there were no blown fuses is if the ring terminals on these studs somehow came loose. Therefore, you will want to check the flange nuts on both of...

  • Trailer Tail Lights Dim When Brake Pedal Is Depressed
    The most likely cause of the tail lights dimming when the brake pedal is depressed will be attributed to a poor ground. Therefore, in order to fix this issue you will need to either try and clean the ground point or run a separate ground wire from each tail light up to the trailer connector. This should then fix your issue but if it does not then please just let me know and I would be happy to further troubleshoot this issue for you. If you need extra wire to run the separate grounds and...

  • Recommended Trailer Winch Wiring Options for 1994 Ford F-250 XL
    To add a trailer winch to your 1994 Ford F-250 XL, the factory 12V power supply will not be substantial enough for the power draw of your winch. You will need to have a separate trailer battery for that function, but you can charge that trailer battery from your vehicle 7-way when you hardwire it. You will need # 10-1-1 wire along with circuit breaker # 9510 and ring terminal # DW05705-1. This will allow you to get the length of wire needed to connect directly to your vehicle battery,...

  • How to Create an Electrical Grounding Plate on DIY Truckbed Camper for Running Lights
    The short answer to your question is, no. You're going to be best served by running your ground wires together and grounding them at a single point on the trailer using a ring terminal like the # DW05705-1 and a junction box like # 38656. Since aluminum not is a great conductor of electricity, that wouldn't be a good choice to create your grounding plate- if you can ground it to steel instead that would be optimal. If you need wiring to run all these grounds together you can use 16 gauge...

  • Connecting Electric Trailer Jack Directly to 12V Battery
    To hook up a trailer jack to a 12 volt battery you need to make the connection from the jack's power wire to the positve post on the battery using a ring terminal, like part # DW05705-1. If you don't already have a battery on the trailer you can add one. You'll need to power it by connecting it to the trailer connector's 12 volt power circuit. You can use part # HS381-9000 if you need to add a 7-way on the trailer. You'll also need a 7-way connector on the tow vehicle, which I can help...

  • Replacement 7 Way Connector for Use with 10 Gauge Wiring
    The Optronics 7-Way Connector, # A7WCB, can be used to replace your current connector which has 2-10 gauge wires. When connecting the 10 gauge wires, as well as the other wires, you can use a ring terminal like part # DW05705-1 if you prefer.

  • Trailer Warning Lights Flash in Vehicles Message Center
    The trailer warning lights flashing in your message center sounds like either a ground issue on the trailer or a corrosion problem between the trailer connectors. I would first start off by disconnecting the trailer connectors and using a bit of electrical spray to clean the pins. Once done, I would also use a bit of dielectric grease like part # 11755 between the two connectors before mating them back together to prevent future problems. Before you move onto the trailer wiring, I also...

  • etrailer Electric Tongue Jack With Footplate Compatibility With a 2005 Artic Fox Travel Trailer
    The Electric Jack w/ Footplate # EJ-3520-WBX will work on your 2005 Artic Fox travel trailer as long as you have a 2-1/4" center hole in the A-frame jack mount location. It is important to check this as some older campers have a smaller diameter center hole. There is only one electrical wire for the jack that will need connected to the battery on your Artic Fox. The ground connection is achieved through the mounting hardware that is included. A 3/8" Ring Terminal # DW05705-1 will make...

  • How To Wire Together Four 12 Volt Batteries To Output 24 Volts
    If your intent is to have 24 volts of output, you can wire 4-12 volt batteries together. In order to connect your 4-12 volt batteries to get 24 volts of output you need some wiring and ring terminals like parts # 10-1-1 and # DW05705-1. You're going to connect your power wire to the positive post on one battery and run a wire that connects that same post to the positive post on the second battery. Then connect the negative posts on both of those batteries to the positive posts on the...

  • Troubleshooting a Tekonska Sentinel Controller
    According to my information the Sentinel Brake Controller does have to be connected to a trailer to operate. There will be a green light that comes on when the controller identifies that the trailer is connected to the truck. After you have this then you will be able to set the gain. If you continue to have no power to your controller after you connect the two, then it sounds like you are missing the 12 volt power wire being routed from your brake controller to the battery used in combo...

  • Troubleshooting Ground Circuit on Trailer
    Good job in testing using a different trailer! You've effectively eliminated the tow vehicle as being the problem. You are absolutely on the right track in suspecting a ground problem to be the cause of the issues you're having. The fact that none of the lighting functions are working would tend to rule out a loose connection or broken wire. A trailer connector will typically ground to the trailer tongue. From the trailer connector, trace the white wire to where it attaches to the trailer...

  • What Amp Breaker Should be Used to Install Brake Controller Towing Trailer with 4 Brake Assemblies
    The diameter of the stud on the Battery Side Bolt Extender # DW05416 that you mentioned is 3/8 of an inch. For a ring terminal designed to fit that you would want the part # DW05705-1. I would also recommend you go with a 20 amp breaker like part # 9506P if you plan to tow a trailer with up to 4 brake assemblies. Otherwise the warranty of the controller would be voided.

  • How to Add Always-On 12V Power Feed to 7-way on 2015 Toyota Tundra
    Since your truck is wired to shut off the 12V trailer power feed when it is not running (to save your truck battery) you will just want to install a separate 10-gauge power wire and 40-amp circuit breaker between your battery and the power wire on the trailer connector. You can use wire # 10-1-1 and breaker # PK54540. You will also need ring terminals # DW05705-1. The linked wiring article will help you confirm which 7-way wire to connect to. Keep in mind that the connected trailer will...

  • How to Ground Optronics Trailer Light ST60RB When Mounting to Wooden Surface
    In order to make a good ground connection with the Optronics Jeep Style Universal Trailer Stop, Turn, and Tail Light # ST60RB you can install a ring terminal and separate ground wire on one of the mounting posts. You can use ring terminal # DW05705-1 and a length of wire like # 10-1-1 to connect to a metal portion of the trailer frame. Any of the three mounting studs can serve as your ground.

  • How to Bypass Trailer Connector 12 Volt Circuit on 2016 Toyota Tundra so it is Hot All the Time
    The 12 volt circuit on the 2016 Toyota Tundra trailer connector must shut off with the vehicle instead of staying live all the time like it was on your Silverados. This feature can probably not be turned off so what you can do is bypass it. To bypass it you will need access to the 12 volt circuit at the back of the trailer connector. On the back of a 7-Way it is located in the 11 o'clock position. You can either remove the wire that is in that location and attach a new wire or you could...

  • Installing a Fuse Circuit Tap and Best Location to Install a Battery Isolation Solenoid
    The Firestone fuse circuit tap # F2526 plugs directly into your fuse box. It provides ports for your original fuse and the accessory system fuse. I attached a diagram for you as well. For the 12V ignition, a good source to use is the vehicles radio, powered antenna or ignition switch. The solenoid will allow the 12V feed to remain active only when the vehicle is running; when the vehicle is turned off the 12V feed will also shut off. You will need ring terminals to connect, such as # DW05705-1. I...

  • How To Install a 7-Way on a 1996 Chevrolet Suburban
    The blue brake output and orange 12 volt power wires are already ran on your 1996 Chevrolet Suburban however, as you suspected they are not yet connected. The rearmost point of the wires near the trailer hitch will need to be connected to the 7-way. Once the rearmost point of the wires are secured to the 7-way you will then need to connect the forwardmost point of the wires to the brake controller and 12 volt power. The forwardmost wires will end in a gray connector under the brake booster....

  • What Gauge Wiring Comes on the 12 Inch AKEBRK-7-SA Brakes?
    The wiring on the Electric Trailer Brake Kit - Self-Adjusting - 12" - Left and Right Hand Assemblies - 5.2K to 7K # AKEBRK-7-SA will be 10 to 12 gauge. I prefer the Deka 10 gauge # 10-1-1 (sold by foot) paired with the Deka Heat Shrink Butt Connectors # DW05745-5 to complete the install. As a side note, with both wires being black, either can be the power wire. It is always a good idea to ground each wire that is not used to its own specific source as well.
