wiring How do I wire this? Is this correct?

[ThomJV]

Sup folks,

Yesterday I made a post about my LED Ford emblem which I'd like to put in my case. The emblem requires +/- 12 volts to work, so I decided to connect it directly to a molex-connector, as I believe the yellow wire is used for 12 volt output (or so I read on the interwebs), so I drew this astonishing schematic before assembling it, and asking you - yes, you! - to check whether this is correct or whether I'm going to break the emblem like a Windsor engine block (Ford joke, haha).

Thanks in advance,

Cheers

TJ

 

PS, I'm a noob at wiring so this might seem like the stupidest request ever, but I'd just want to be sure before I do it, if it means preventing an accidental camp fire

 

PPS, I suck at jokes.

 

Here are the schematic and a puppy

yea you can also just wire it right to the power supply without the connector but yeah your ms paint diagram seems correct

thats the neat thing about computers and cars they are both 12v so lotsa stuff is compatible back and forth

Yellow is +12V, black is GND. +12V goes to +, GND goes to -

Ain't rocket surgery

I dont think puppies come with molex connectors. This will be a bit more work than you think.

Something else to note i didn't know long ago , but EVERY black wire coming out of the power supply is ground for every voltage , so a lighted thing that needs 12v , 5v , or 3v all use the same ground wire.

So technically speaking it doesn't matter which ground wire I use, as long as I use the yellow one for 12 volt?

Correct. 

 

Ground is ground, no matter what the voltage of the other wires.

Gotcha, thanks

Do not do this a vehicle usually runs at 14 volts not 12 and its not well regulated.

Erhm, this isn't for a vehicle.

It's a vehicle badge that will be put on a PC case <___<

Well … that'd be weird since car batteries are 12V. More complex electronics might run on different voltages, yes and very modern cars do use other voltages as well, but I have my serious doubts that a simple emblem is running on anything else than 12V.

Your logic is reversed. Indeed a car's power rail has lots of noise and wide voltage ranges from down to 8 volt when you're starting the engine up to 14.5V while charging from the alternator. That means the badge is designed to be able to able to cope with all of that. Supplying it from the, relatively, clean 12V computer power supply should make it extra happy then.

Fully charged lead acid can be as high as 16V

The box says 12 volt, so surely 12 volt from a molex should be fine right? Also, it's an LED light, it should be perfectly fine running on a slightly lower voltage, I tried a 9v battery and, although a bit dim, it works fine.
