Once again I am using the Engineering chat as I think my question is more theoretical rather than 'diy advice'. If I am misusing the forum, please let me know.
This question is back 'in the car' again, but I think it is a fundamental question about 'how electricity works', more so, a circuit (as I understand it, the flow of negative charged electrons to a positive terminal).
My project is to install another car accessory, but I don't want to use the cigarette lighter as I am fed up with wires spewing from the console. As with hardwiring kits, I want to piggyback into the fuse board, thus hiding my 'wiring in'. Given just about everything has a USB-A plug at this end, I am surprised there isn't an off the shelf 5V 'female USB-A to piggyback fuse' product.
There are a few hard wire USB sockets, but they all appear to have two wires, instructed to connect to the positive and negative terminals of a battery.
Most are styled like 'cigarette lighter barrel', but I like the simple version, picture included (my only hesitation being that I can't find a reputable manufacturer).
So, how do I wire in a positive and negative wire into a generic piggyback fuse? Not wishing to insult you guys, but I have included some pictures for clarity (perhaps more so for any others viewing this question).
Can I simply twist the positive and negative together, then crimp directly onto the single wire coming from the generic piggyback fuse?
Bearing in mind my total lack of understanding of electricity, and therefore not knowing if it is a really stupid question, I will attempt to explain my reasoning ...
TBH I haven't given much thought to circuits when using hard wiring before, but it has occurred to me that the fuse has two spades, which I am guessing are inserted into positive and negative 'sides' of the fuse board. My question comes from the fact that the piggyback fuse has a single wire, used to connect the accessory that it is powering. As the externally powered...
