Video Transcript for Spectro 12-Gauge Mini Fuse Holder Review

Shane: Hey everyone, Shane here with Today, we're going to be taking a look at the Spectro Mini Fuse Holder.This fuse holder is designed to give you a fuse circuit if you're wiring up anything. We're actually going to be installing this for a power wire going to a Furrion charging station. This is for mini fuses. So, whatever circuit you are running through this, you want to make sure you're getting a compatible fuse to go in it. And this is a mini fuse, what it looks like.

It does not come with your fuse holder, so you want to make sure you pick one of those up. It's got a nice durable, rubber construction. The wire is coated, and it's going to have a nice cap when you install your fuse to help protect it. Being a mini fuse holder just makes it nice for if you have small areas that you need to fuse up to a battery, like we have here, it makes a little bit easier to fit this in there rather than one of the bigger size ones.So, let's go ahead, go down here and we'll show you how to get it hooked up. Here, we have our power wire coming from our charging station for our Furrion speaker.

We'll go ahead and strip it back. We're going to add on our butt connector. If you don't have butt connectors, you can find them here at etrailer. We'll take our fuse tap or our fuse holder. We're going to add one end into our butt connector.

That current's on. Our other end, we're going to add on a ring terminal. We can go ahead and connect to our battery. Once we have it connect to our battery, we'll go ahead and add in our fuse. Once you have it connect to the battery, you have your fuse in place, then you're ready to go.That's going to do it for a look at the Spectro Mini Fuse Holder..

Ask the Experts about this Spectro Accessories and Parts

  • Is a Fuse Necessary When Wiring a 7-way If 12V Wire Already Is Fused
    If the truck has a 12V power wire dedicated to the trailer wiring that is already fused, you do not need to add an additional fuse. For example, on newer GM trucks, the 12V power wire from the factory tow package is ran to a 40 amp fuse in the fuse box. In this instance, it is not necessary to add an additional fuse. If you have to run a new 12V power wire, then we recommend adding a 40 amp circuit breaker, like # 9510, before the battery. If you would like to let me know the year,...

  • Roadmaster Stop Light Switch Kit For 2018 Jeep JL Wrangler Unlimited
    The Roadmaster Stop Light Switch Kit # RM-751490 will work for your 2018 Jeep JL Wrangler Unlimited. As you know the fuse tap does not work with the Jeep JL because it will not fit in the spot in the fuse box. All you need is a fuse holder # SWC9545 and the 10 amp fuse that comes with # RM-751490. That connection will go right to the battery. I have a video attached that shows this product being installed on the 2018 Jeep JL Wrangler Unlimited. The part about the fuse starts at the...

  • Availability of a 4-Flat and 5-Flat Wiring Harness to Power an Air Compressor on a Trailer
    With the set up on your 2013 Lincoln MKX, you best option will be to install the T-One Vehicle Wiring Harness, # 118519, and then use the Tow Ready 4 Pole to 5 Pole Wiring Adapter, # 20036. This the adapter will connect your 4 pole vehicle plug and 5 pole plug on your trailer. The trailer lights will be connected to your vehicle. The extra wire then can be wired up to the battery to power your air compressor. Depending on the amp draw of your compressor, I also recommend you wire in a...

  • Replacement Fuse Holder or Circuit Breaker for Use with Husky Brute Electric Trailer Jack HT87247
    You can use either a fuse holder such as Spectro # SWC9545 along with a locally-sourced mini fuse, or you can use a 30-amp auto-resetting circuit breaker # PK54230 to protect the circuit that powers your Husky Brute Electric Trailer Jack # HT87247.

  • Wiring Additional LED Lights On Yahama Royal Star Tour Deluxe Motorcycle
    You would need to install a switch for the lights from the 12V battery. Since you are installing LED lights, you should not have any problems with power draw. We do not carry switches that are specifically designed for motorcycle lighting but you may want to take a look at the product page I attached for the switches we offer. You can add an inline fuse holder like part # SWC9545. Each of the lights will need to be grounded to the motorcycle so I recommend ring terminals like part #...

  • Stop Light Switch Wiring For 2021 Jeep Wrangler Unlimited
    For your 2021 Jeep Wrangler, you actually can not splice into the brake wire. For this reason, you will want to use the Roadmaster Stop Light Switch Kit # RM-751490 instead. This kit will connect to an inline fuse to your vehicles positive terminal on your battery, and the other wire would route up to the front of the vehicle by the electrical connector. You will need to use the Spectro 12-Gauge Mini Fuse Holder # SWC9545 and the Ring Terminal # DW05705-1 with the included 10amp fuse...

  • Replacement 30 Amp Fuse Holder for Husky 3K Electric Trailer Jack
    The Husky 3K powered trailer jacks use a 30 amp fuse. What I recommend instead of replacing the fuse and wiring is to use a circuit breaker, # PK54530, so that it will auto-reset. Then you just need some 10 gauge wire, # 10-1-1, sold by the foot. Or for a fuse holder you can use # SWC9545 with a 30 amp mini fuse obtained locally. This is a 12 gauge wire but given the short distance from the jack to the battery this small piece of 12 gauge wire will work perfectly fine. This will not auto-reset...

  • How to Install the Peak Backup Camera Part # PKCOBU7 on a Horse Trailer
    The first step for installing the Peak Backup Camera Part # PKCOBU7 would be to mount the rear view camera somewhere inside the horse trailer. You can use the Self-Tapping Fasteners for License Plates and License Plate Frames part # CR80430 to install the bracket/camera. Once the camera is in position, you will have two wires to connect. One will be red for the 12 volt power and the other will be black for the ground. Strip about 1/4" of the jacket off of each wire. Once done you will...

  • Wiring Options for Installing MaxxFan Deluxe 12V Roof Vent MA00-06200K
    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. Since this unit draws a maximum of 5-amps current you'll want to ensure you install it on either an existing lighting circuit that is rated for that much power...

  • What is Needed to Install Interior LED Lights in an Enclosed Trailer
    Installing the Optronics LED RV Interior Light, # RVILL34, should be a fairly easy project. The two wires on the light are 12 gauge. The white wires can be grounded to the trailer body, the black wires are your power wires. Using # 12-1-1 you can connect to the black wires and run this wiring to where you are going to install your battery. Using a 12 gauge wire nut, found at any hardware store, connect all the light wires and the power wire from the battery together or you could use...
