Utilising the piggyback fuse

[keithmerc220]

I will be use one of the options listed below to install my reversing camera into Fuse position 73. Richard recommended replacing the current 15A fuse with a 5A fuse for the camera, taking into consideration the thickness of the cable. Could you possibly provide information on the specific location of each fuse in the piggyback? Thank you.

There is a 5a wire next to another wire, and a 15a wire located in close proximity to the blade.

Ensure that you insert it into the socket with the right orientation.

Unfortunately, it is still in Chinese. Do you possess a response for a Bear with a significantly limited intellect, if you please? I possess expertise in both culinary arts and computer science. However, automotive electronics...

Connect it by inserting the red wire into the fused side of the fusebox, specifically on the side where the old fuse is removed, known as the 'dead' side. If that is comprehensible.
The original car fuse is inserted into the two connections that are furthest away from the red wire.
The new circuit fuse is inserted into the connections that are in closest proximity to the red wire.
Note that the two fuse connections are distinct and might contribute to the state of being perplexed.

If I maintain the orientation of the fuse that I remove, would it be correct? The situation is somewhat perplexing. Laughing out loud
Indeed, you have keenly seen that they are distinct. How peculiar!

To add extra complexity:

Whenever I want to add an additional component to a car, I simply get the necessary power supply from an available, but unused, fuse connection in one of the fuse boxes. Most vehicles have unused connections that provide a continuous or ignition power source, which may be used for this purpose.

On several instances, a crimp on spade connection with an inline fuse inserted into the live side of a connection has proven effective without requiring any additional load on an existing circuit.

I am experiencing cognitive overload.

There is no specific orientation available.
When the fuse is removed, one connection will have an active electrical current on either the auxiliary or ignition circuit - depending on the circuit you have selected - while the other connector will not have any current.
When inserting the add-a-fuse, ensure that the red wire is connected to the side of the fusebox connection that does not have an active electrical current.
Next, insert the original fuse into the socket that has two spade connections, except the one with the red wire (a case of negative logic). This will reactivate the original regulated circuit. Insert the new 5 amp fuse into the alternate circuit, ensuring that it is connected to the red wire. This will activate your 'new' circuit and provide it with protection.
Alternatively, you may follow Kenny's approach, which is my favourite choice if there happens to be an open slot in the fusebox.

The one I want to use is the 15a bottom one 71 (Front cigarette lighter with ashtray lights - Front car interior power outlet). The car is a 2011 S204 model.

Unless I get other advice, I will proceed as planned. Laughing out loud

[Chrishazle]

That is the circuit I would most likely use. However, I would do a thorough examination of those 'extra' slots by use a testlight in combination with a fuse diagram, and if possible, following Kenny's approach.
To maintain simplicity.
