Video Transcript for 3M Wiring 44-5310A Review

Today, we're going to review part number 44-5310A. This is the 3M ring terminal for 12 to 10 gauge sized wire with a ring inside diameter of 3/16ths of an inch. These ring terminals are used for all types of electrical work where wires need fastening. This one is for use with a 10 or 12 gauge sized wire. It does have the vinyl insulation sleeve, which is yellow, and then the ring terminal, the inside diameter is 3/16ths so it is designed to fit on a stud size of 3/16ths of an inch. Basically, want to show you here, I got an example right here of a 12 gauge sized wire. What you would basically do is just side this into ...

You don't really want to have it sticking out. You could, but what I like to do is put it right there. Then, you're going to crimp, have a set of . This is a wire stripper with, down here is the crimping portion. If you just stick that in the very .. Put it right over there and then all you have to do is push down just like that.

Once you push down and hard enough, you can see that it crimps that wire to this ring terminal. You can see that you have a good connection. That's the reason I don't like to have the wire stick out too much because you don't want any of that exposed so if you just keep it under that insulation sleeve, you should be in good shape. That should do it for the review on part number 44-5310A. This is the 3M ring terminal for 12 to 10 gauge sized wire with the 3/16ths inch ring inside diameter. .

Exactly as described. Great to order from one supplier and have all the pieces arrive together for our project.

Worked well with everything downstream of the primary wiring. Just wasn't big enough for the primaries, got that at a local hardware store.

Replaced trailer wiring over a year ago and lights still work great. No issues with these connectors. Used them in new junction box.

Had this sent to the person I purchased my Used Lance 1030 from before picking it up. He said this was a Super High Quality Product! Nice and Color Coded Heavy duty terminals. His Electrician is removing the end of the Lance plug so I can just use the 7 bladed plug at the end of the bed of my truck next to my License plate (2017 F350 PSD, DRW Super Cab, 8 Foot bed)

  • New Side Marker trailer Lights are Very Dim
    It sounds like a bad ground connection. Ground problems normally show up when there is more draw on a system such as when you have the running lights on and then use another function like a turn signal or brake light. But can also appear when changing out lights. Make sure that the vehicle side and trailer side connectors are clean and free of corrosion inside and out. The main connector grounds should be attached to clean and corrosion free bare metal surfaces. The light grounds should...

  • Troubleshooting Poor Trailer Brake Performance After Replacement of Brake Drums and Assemblies
    There are some things you can do. First, I'd make sure the brakes are properly adjusted. Even if the brakes are self-adjusting, you'll need to manually adjust them initially, or find a large parking lot and run through several braking cycles at 20 or so mph to adjust the brakes. Also, regardless of if you have manual adjust or self adjust, the brakes will need to be burnished in or broken in, if you will. If you click the provided link, you can take a look at a help article that explains...

    Grounding an electrical wire, which is all this is, entails finding a paint and corrosion free spot on the frame of the vehicle that you can connect the wire to.

The steps for pairing the remote are listed below for you to use as a reference in the event that you want a quick place to refer back to. 1. Turn ignition...

  • Junction Box To Wire Lighting on Flatbed Trailer
    Yes, the Pollak 10-Terminal Junction Box part # PK52248 will work to wire up the lights on your flat bed trailer. The posts on this particular junction box are not labeled so you can connect your functions to the box on any of the posts. Since you are just doing lights, you can just leave the rest of the posts unused without any issues. You will need ring terminals part # 44-5310A to connect your wiring to the terminals.

  • Troubleshooting 7-Way Trailer Wiring with Colors That Don't Match Functions
    Wiring by function is the route to go for your situation. This is done by testing each wire of your trailer individually. The easiest way is to use a 12V battery and connect the negative terminal to the trailer's ground on the frame and then use the positive terminal with a jump wire to connect to each individual wire. One wire in your 7-way will be the ground wire. You will want to find this one first because it will cause a spark if you connect the battery to it. You can trace...

  • How to Upgrade Trailer from 6-Way to 7-Way RV-Type Wiring for Lighting and 12V Power Functions
    The best way to match up your different vehicle and trailer wiring is to install a 7-way on the trailer. It is much easier to work on a trailer's wiring than a vehicle's. And doing this avoids adapters that can often end up being a pain in the long run. A standard RV-type 7-way trailer setup includes all the lighting signals for the trailer plus a brake circuit for the trailer's brakes, a reverse light circuit for trailers that have clear backup lights and a 12V trailer power circuit that...

  • How to Upgrade 6-Way Trailer to 7-Way to Match Connector on 2014 Dodge Ram 1500 Pickup
    The best way to help your Ram pickup with a 7-way to get along with your 6-way-equipped trailer is to upgrade the trailer to a 7-way. This is a simple process of installing a 7-way plug like # H20046 with a junction box # 38656 and ring terminals # 44-5310A. All you need to do is apply 12V power to each trailer wire to confirm its function and then install each wire in the junction box at the appropriate terminal.

  • Troubleshooting Trailer Brakes That Show Intermittent Overload Error Message on Prodigy Controller
    It sounds like your Prodigy brake controller in your 2004 Dodge Ram Pickup is sensing an intermitting short in the trailer wiring. Since you have checked the brake magnets and have found them to be okay, I suggest tracing the entire brake circuit for signs of damage or corrosion. Follow the brake circuit wiring from each brake all the way to the trailer plug. Look for cracked insulation and spots where it is worn off, especially near points where the wire bends and where it comes into...

  • Troubleshooting Trailer Side Wiring Connection With Smaller Holes
    I'm glad the new Hopkins 7-way was an easy installation. The apparent difference in size of the connector on your trailer is odd as the blades and corresponding connections are industry standard size. It is possible that your trailer doesn't have the industry standard connector, but that would be odd. The only other thing that would cause a connector to not fit is if there is corrosion built up on the inside of the trailer wiring connector. You may want to take a look at that possibility...

These ring terminals work great for a connecting a trailer connector like # H20046 you asked this question from to a junction box like # 38656.
