This may not blow at the correct amperage or fast enough to protect what ever is attached to that circuit. Fuse taps are clever pieces of metal and plastic that can turn 1 fuse position on your fuse box into 2 separate fuse positions. They are a good generic way to separately power an additional circuit. Step 3: Identify the type of fuse,so you can get the right size fuse tap and accessory fuse. The owner's manual should identify the type of fuse used in your vehicleSo with this in mind, the diagram on the left shows how the fuse tap is configured (ignore the 4 dots). A fuse can go in either way around because it’s just a link in the circuit. However, because you are taking a live feed from the fuse box to use it elsewhere, it’s of upmost importance that you put the fuse tap in the correct way around. Experienced dash cam installers will know there are plenty of other options, but they’re car model-specific and may involve splicing into existing looms. If in doubt get a competent and qualified auto electrician for that type of installation. Dash cam installation: no more suction cups

If you put the fuses in the wrong positions, you may get fuses blowing or electrics getting damaged. This is because the items will be protected with incorrectly rated fuses. So lets have a look at how a fuse tap is configured - This will help you understand how to install it.

The following pictures show how each fuse affects the circuits, starting the the fuse tap in the correct orientation. (note that in my example, the red wires are positive and the yellow wires are negative). The fuse you remove, it must be placed in the slot nearest to the metal prongs. This part of the circuit replaces the original position of the fuse.

Using two feeds tells the camera which mode it should be in. In most cases, it also avoids flattening the car battery. This is because dash cam parking modes are usually designed to switch off at a pre-set voltage. a>
