ESUPPORT 12V 24V Standard Add A Circuit Fuse Tap Piggy Back Blade Holder Plug Socket Car Pack of 5

Worked like a charm. So much easier than tryingto find a wire to splice into, and can be removed without a trace. Found the circuit I wanted (switched, on key) pulled the original fuse, placed it in the add-a-fuse (bottom slot), put a fuse for my new accessory in the top slot, plugged the add-a-fuse into the now vacant slot in the fusebox. Insert the power lead from my new device into the provided crimp connector, crimp and Done! Just be sure to check the polarity (which side is hot) and plug the side of the add-a-fuse that is AWAY from the accessory lead into the hot side of the fusebox. Otherwise you will be adding the load from the new accesory to the original fuse. The easy test is to install the add-a-fuse with only a fuse for the new accessory in the top slot. Test for voltage on the pigtail. If there is power on the pigtail you're good, if not rotate the add-a-fuse 180 degrees and test again. Don't forget to install the fuse for the original device you're "piggybacking" onto in the bottom slot of the add-a-fuse, and the total load (original plus new accessory) should not exceed 30 amps or you might melt the connector in the fusebox.

Easy to add power source and sturdy.

Excellent product. Fit perfect, worked perfect but 2 of them were cracked on the plastic

This is a great way to tap into your fuse box power without having to cut or splice any wires or lose any fuses by dedicating them to another purpose. I have used these several times and are especially handy for taping into a power source that is only on when the headlights are powered on without having to do much thinking. For example, I purchased a compass that has a built-in light, but I didn't want it on 24/7 and only wanted that light to come on when I needed it, so I was able to use the fuse location that protects the head lights, allowing the compass light to only come on when the head lights are on. Your owners manual will describe what each fuse protects, so finding the appropriate fuse to "tap" into is easy. One note, the product description in one place says "Compatible with mini blade fuses", which is in error. This particular set of fuse taps are for the standard size blade fuses, which is mentioned in several areas of the description, but I noticed one line was in error. To be clear, these "fuse taps" allow for two fuses in one fuse location, so each of the two fuses can be matched for their individual load.

These are really smart to keep on hand and easier to use than trying to fuss with running wires all over your car just to get power to something. They are good quality and long lasting. With proper installation, you can easily add circuits to your car that are properly fused. I would definitely recommend these to others.

Great product and a must for installing auxiliary lights and switches. Make sure you order the right size. Toyota 4Runner’s take the smaller fuses.

Boy what a great idea, This product was easy to use, and safe. I used it to add a power inverter into my RV. I wanted a smaller inverter that would turn off with the key so I would not have to remember to turn it off.This product made the electrical connection very easy. Took 2 minuets to get a safe, fuse protected power connection to my 12 volt fuse panel.5 starts,

These are good quality, they lay nice and flat on the fuseblock, and have thick wire and a ready-to-go wire crimp on the end. Hard to beat for the price, and with the double fuse design, these little guys are a good source of "spare" fuses for if you blow a fuse on another more important circuit.
