installing 12v items

[ATARI]

plug one end into empty fuse
other end to ground

is it that simple?

That's ghetto but yes
You can use wire splicers and tap into a 12v source as well. Ignition, cigarette lighter, radio just to name a few.

Is it sensitive electronics that need 12Vdc exactly, or "car" stuff that can handle the dirty, fluctuating 11 to 15V "DC" that your car actually puts out?

This. Car electronics are designed to work on the 11volts your battery will dish out under a minor load, or the full 15 volts the altrenator will crank out once the car is running.

Another problem for electronics is that alternators don't put out DC, but this half-assed rectified shite with lots of ripple:

ghetto?

how should i do it?

Run a properly fused wire of sufficient gauge from the positive terminal of your battery to a switch, then to the positive connection of the device you want to power. Run the negative lead of the device to a piece of bare metal which connects to the car's chassis to complete the circuit.

how do properly fuse something

[sr20s14zenki]

Get a fuse kit from canadian tire, its a simple wire with a fuse receptor in the middle. Voila...fused.

so an inline fuse... alright what ones do i use?

[punky]

find one that is a bit higher than the max current rating of whatever equipment you are using.

the current rating? ok

thanks

it says you drive an 06 jag, why not either pay someone to do it for you or pay someone to teach you?

whats that have to do with it?

maybe id like to learn by asking

[TurboD]

lets start with this, still you haven't explained WHAT it is you are trying to wire up, or WHAT car it is in question (these are very key points)

second, leaning by searching > learning by asking

the internet is a vast ocean.

questions about nothing will give you answers related to nothing ;)

if it's pulling any decent amount of current (like an amp or foglights) then USE A RELAY don't just run it through the switch!

(someone else can explain how to properly wire that)
