Video Transcript for Hopkins 12-Volt Power Socket Installation

Today we're going to take a look at and also show you how to install the Hopkins 12-volt power socket with power wire and fuse assembly. Part number is HM5515. Now this can easily be mounted anywhere we need a 12-volt power source. It's great for emergency use, camping or tailgating, but a lot of our customers like to use it as a power source for their supplemental braking system. That's the application we're going to be showing you today, but it installs the same regardless of what you're using it for. This is what our kit's going to look like when we get it out of the package. Here's what we're after: a 12-volt power supply.

This is going to be connected directly to our battery. Whether your ignition causes all the outlets in your vehicle to turn off, or whether you're adding this to a different application, whatever the case may be, this is going to give us constant power. Got a nice dust cover there that's going to prevent things from getting in there. We've got a surface-mount setup here, so we've got a piece of foam tape on the back that's going to help mount it to our surface. We've also got an area on each side where we can put in just a small self-tapping screw to give us a little extra security. The red wire is going to go out to our power source, which is going to be our battery.

The white wire we're going to ground somewhere underneath our dashboard. Now the first thing we need to take care of for our installation is getting our 17-foot length of power wire from inside of the vehicle outside of the vehicle. We're going to be mounting our outlet right here so it's convenient and easy to get to. If we go straight back from there, we've got a grommet on the firewall. Let's use that grommet to pass our wiring through.

We're just going to make a very small slit in the grommet. That should give us plenty of room. Now I'm using just a piece of airline tubing here but you can also use a coat hanger or a stiff piece of wire. Now I'm just going to use some electrical tape here and tape my wire right off to my pull wire or my airline tubing, whatever you're using. Now we're going to leave a little bit of extra wire here on the inside, but we're going to snip off what we don't need. We'll strip the end of that back.

You can see we've already got a butt connector on the end of our outlet there, so we'll just have to stick it in there. Then we can get it crimped down. Now to attach my ground wire I'm going to go to the stud that's located right here. This is the bracket for the emergency brake cable. There's a stud that goes right into the firewall right there. Want to remove that nut. We're going to place the ring terminal right on that stud and replace our flange nut. Now we're going to mount right up here. Got a nice area with nothing located behind it so we don't have to worry about anything we might drill into. We'll pull cover off of that adhesive, get it up in place nice and level. You can see I ran my wires out of the top there. That's going to make it a little bit easier to get everything tucked away. We're just going to use a couple of self-tapping screws that have a round head so they'll fit in properly here. Now we just grab a couple of zip ties and bunch up any excess wire that we might have here. Just make a nice little bunch. This is going to give us excess wire in case we ever need to make any changes or any repairs. Then we'll zip tie it off right up here to a factory wire loom. Now we're just going to route our power wire just down and out of the way. We'll bring it right over here. We're going to be going to the positive side of the battery. Just use a little zip tie there, get it held in place. Anywhere else you think you can get one in to help just keep the wire from moving around is a great plan. Now on our fuse holder here, see we've got our fuse in place. We want to get that out of there, set it aside for now. We'll replace it in just a minute. Since we're making a connection here on the outside of the vehicle, I like to get rid of the standard butt connectors. I'm going to strip that back and what I'm going to add is . this is a heat-shrink butt connector. This is going to provide us with superior moisture protection in the event that water we're to get up in here and stuff like that, we won't have to worry about any corrosion. We'll cut off just a little bit extra. That way, if we ever need to change it or make any repairs, we'll have some extra wire to do so. Get that other side stripped off there. That's going to go right into our fuse holder. Give it a good pull, make sure it's solidly connected. Then we can just use a heat source. I'm using a lighter. You can also use a heat gun. You could use a little mini-torch, whatever you've got handy. You'll see how that shrinks down. There's actually a little bit of gel that comes out of that end. That acts as a sealant or as a glue to keep our connection free of any moisture that might want to try to get in there. Now we'll pop the cover off our battery. You see we've got a little open hole right here. Some of them will have a stud that's already in place. This one doesn't, so what I'm going to do is just use a small screw, place that on, place my screw down through. Then on the other side I'm going to thread on my nut. That's nice and secure. Pop that cover down closed and now our excess wiring. We'll tuck that right underneath and we'll use a zip tie to secure it. Let's take our fuse here, slide it in place. Then we'll go in and test that outlet and make sure it's working. Now to test it out we just want to pop our cap off. I'm going to use just a charging port. It's got a light on it. If we've got 12-volt power, we'll have a green light come on. Working as it should. That's what we're looking for. That's going to complete our look at the Hopkins 12-volt power socket with power wire and fuse assembly, part number HM55115.

Good as advertised

Have not installed this as it is larger than I thought.
Looks to be good quality!

Decided to use a different connector as this was too big for my intentions.
Chuck - 01/27/2022

Used this to add a 12 volt power outlet for my RVi Tow Brake System in the overhead console of my Winnebago View for the remote monitor. I have a 2016 Winnebago View and there was no good place to put the RVi plug in monitor on the dash console. This worked great!




by:

Put this on dash panel of our Sprinter 3500 frame class A RV for a plug-in on our new wireless towing device sync box to vehicle brake box. Easy to install on dash could set power socket were I could see information on wireless box and plenty of wire and fuse link to be able to hook up direct to RV batteries not the main vehicle battery.




by:

I’m giving it 5 stars but truthfully I didn’t need it and returned it for refund so your on your own with it ..




by:

Just what I needed, it is well made and will work great with my supplement braking system I use when pulling my jeep with the RV. As always E trailer sent it quick, and knew what I needed.


Comments
Still working great and looks like it just came out of the box.

The power socket arrived quickly and came packaged as advertised, installed easily in our camper. A simple product that will add much convenience to our camping. Just installed so we don't know the long term reliability of this product yet.

  • Troubleshooting Hopkins 12-Volt Power Socket # HM55115 Only Supplying 8V of Power
    I would start off by making sure that the ground of the Hopkins 12-Volt Power Socket # HM55115 is secure and connected to a clean, bare-metal surface. Even some paint could potentially cause issues. Aside from that I would just make sure that none of your wiring is damaged. Let me know if neither of those solutions work and I can help you troubleshoot further.

  • Where to Attach Ground Wire on RV to Install Hopkins 12-Volt Power Socket # HM55115
    The Hopkins 12-Volt Power Socket # HM55115 can be installed with the white ground wire attached either to a clean bare metal surface on the RV frame or directly to the negative terminal on the battery, as you suggested, since the battery negative terminal grounds to the RV frame anyway. The battery terminal ground is the best option since the socket must be securely grounded to operate properly. The kit includes 17-feet of 14-gauge primary wire for the positive terminal connection to...

  • Wire Size and Amperage Rating of the Hopkins 12-Volt Power Socket with Power Wire and Fuse Assembly
    The wire size of the Hopkins 12-Volt Power Socket with Power Wire and Fuse Assembly # HM55115 is 14 gauge and the amperage rating of the fuse is 20 amps. So as long as you stay under 20 amps this product should work well for you.

  • How To Install 12 Volt Power Outlet In Truck Bed
    The best option I have to install a 12 volt power outlet in a truck bed would be to use the Hopkins 12-Volt Power Socket with Power Wire and Fuse Assembly part # HM55115 and wire this directly to the battery. This would need to be wired directly to the battery as it will provide the outlet with constant power. I am not aware of any adapter that would pull power for the other circuits which likely aren't rated high enough for what you need anyway.

  • Dimensions of Hopkins 12-Volt Power Socket # HM55115 and # HM55125
    Hopkins 12-Volt Power Socket # HM55115 and # HM55125 have the same dimensions. The base has a diameter of 2-3/4 inches. The overall height is 2-1/2 inches. On both the wires exit at the bottom (or the side with the light if using that model). So if the wording on the cap was facing right side up, the wired would exit from the base at the bottom.

The only real difference between the Hopkins 12-Volt Socket with Utility Light with Power Wire and Fuse Assembly # HM55125 and the Hopkins 12-Volt Power Socket with Power Wire and Fuse Assembly # HM55115 is the utility light with on off switch.

  • Needing a Heavy Duty 12v Power Outlet
    The best option would be to use the Roadmaster 12-volt Outlet Kit, # RM-9332. This kit is was designed to be used as a way to connect the 12-volt connection on supplemental braking systems used when flat towing a vehicle behind a motor coach. What I like about this kit is it has a 20 amp fuse wire inline of the outlet. The outlet has a two wire application, one to ground and the other, with the inline fuse, to 12-volt power. Power supply to the trailer can be run through the 12-volt...

    A very simple solution would be the Battery Adapter - 12-Volt DC Cord to Battery, # RM-9332. Connect the battery terminal ends to the battery and plug in your electric blanket in the 12 volt end. Depending on where you will have a battery, the 3 foot cord may or may not be long enough.

It comes with an extra 17 feet of wire to connect to a battery and includes an in...

  • Can This Unit Be Installed With An Auxiliary Switch To Function When Truck Is Off?
    The Performance Tool 12-Volt Heater and Defroster can be left on between power cycles with an auxiliary switch if you desire. It will draw about 13 amps at 12 volts which equals out to about 156 watts, so you will want to take that into consideration for your application. I don't recommend leaving it on for long periods of time as it will eventually drain your vehicle battery and the manufacturer states that the heater shouldn't be ran for more than 20 minutes at a time with 5 minutes...

  • Recommended 12 Volt Accessory Socket Rated For 30 Amps or More
    For a 12V socket with fuse, I recommend the Hopkins 12-Volt Power Socket with Power Wire and Fuse Assembly, # HM55115. This socket will allow for a larger fuse if you upgrade the 14 gauge wire to 10 gauge like # 10-1-1. This will take some customizing as these 12V systems are typically made for 20 amp capacity. You will add the red wire to the battery and use the inline fuse assembly and then attach the white wire to ground. I've attached a review video as well as an installation video...

  • Recommended Camera to Use for Inside of Motorcycle Trailer
    The Rampage Wireless Backup Camera # RA7710 that you referenced is a great option for a wireless camera, since it has the magnetic base it can be mounted in a variety of places around your vehicle or trailer. My contact at Rampage said that you can use the camera while it is plugged up to power, but since it is compact you will get feedback through the microphone. The video will work fine, but you will need to turn the volume down because of the feedback. The best way to use this camera...

  • Camera for Use Inside Enclosed Trailer
    Since you do not want to run wiring the best thing you can do is install a 12 volt battery in your trailer like you mentioned, and you can connect the Rampage Wireless Backup Camera # RA7710. This would be the easiest method and what you will do is use 10 gauge wire # 10-2-1 to connect to battery power and ground to the Hopkins 12-Volt Power Socket # HM55115, which will connect to the Rampage camera. This camera does have a light, making this the best option for you. I have added links...

  • Can MaxxFan Deluxe Roof Vent # MA00-07500K be Wired Directly to Battery
    There is no reason why you cannot power your MaxxFan Deluxe Roof Vent # MA00-07500K from your battery using a 12-Volt DC Outlet # HM55115. You will then just need a plug for the socket, rated properly for your power application. You may want to install a 10 amp fuse with a Fuse Holder # SWC9538 as well to help protect the circuit.

  • Recommendation to Add 12V Power Socket on 2018 Honda CR-V
    To add a 12V power socket for you to draw 1-2 amps you will need to add a separate wire because you can't tap into your trailer connector # 118741. You can use the Hopkins 12-Volt Power Socket with Power Wire and Fuse Assembly # HM55115 or Roadmaster # RM-9332. Your other option since you will need to run wire anyway is to use an adapter like # ETBC7L which will give you a 7-way connection but only the 4-way and 12V power functions you can tap into. It will come with wiring and circuit...

  • How to Add 12V Socket Wells Cargo Enclosed Trailer
    It's extremely likely that the taillight circuits on the trailer won't have enough power to run your ice chest and the taillights simultaneously, so you wouldn't want to power the cooler from your taillight circuits. However, if your enclosed cargo trailer uses a 7-way trailer connector, there should be an active 12-v feed directly from the tow vehicle battery that could be used for this purpose. I'd recommend using the Hopkins # HM55115. The red wire from the outlet would connect to...

  • Current Capacity of Hopkins 12-Volt Power Socket with Power Wire and Fuse Assembly HM55115
    The Hopkins 12-Volt Power Socket # HM55115 uses a wire gauge that can safely support up to 20-amps and that is the value of fuse supplied with this kit. I can't recommend using a 30-amp fuse in this item. What I can suggest is making your own 30-amp capable outlet by using a 30-amp auto reset circuit breaker # PK54530, 12V power outlet part # DG6112VP and 10-gauge duplex wire # 10-2-1. You'll also need some ring terminal connectors like # 44-5310A, push-on connectors like # DW05709-1...
