Review on 󾓦 ESUPPORT 12V 24V Standard Add A Circuit Fuse Tap Piggy Back Blade Holder Plug Socket Car Pack of 5 - Efficient Power Solution for Car Electronics by Jimmy Bores

Runs like clockwork. It's a lot easier than trying to find a wire to insert and remove without leaving a trace. I found the circuit I needed (key turned on), pulled out the original fuse, put it in the extra fuse (bottom slot), put the fuse for my new accessory in the top slot, put the extra fuse in the now vacant slot in the fuse box. Plug the power cable from my new device into the supplied crimp connector, wrap it around and you're done! Just check polarity (which side is hot) and plug the side of the extra fuse away from the accessory cord into the hot side of the fuse box. Otherwise, add load from the new accessory to the original fuse. The simplest test is to install an extra fuse by just installing the fuse for the new accessory in the top slot. Check the voltage on the pigtail. If there is power to the pigtail then everything is fine, if not, rotate the auxiliary fuse 180 degrees and check again. Make sure you put the fuse for the original device you are "plugging in" in the bottom auxiliary fuse slot and the total load (original plus new accessory) must not exceed 30 amps or you could melt yourself. socket in the fuse box.
