There is no simple way to explain it. But you should know whether it fits as the plugs are either 6 pins, 4 pins etc. and they only fit for a specific jack. It doesn't matter which wire you use but keep in mind that the neater they are the easier it is to fix things later on. I did a quick google and found this:

Hope it helps!

SOURCE: Power supply

HI Pierre,

I am going to have to go draw something up real quick for you.
In words, The main big connector goes to the only connector on the motherboard that it will fit in.
The smaller connectors rectangular connectors plug into the Hard Drive and another in the CD/DVD drive. Als you may have another connector for a Disc drive.
All the Connectors are specifically shaped not to fit where they do not belong.

There is no wiring diagram.

you simply hook up the motherboard with the coded connectors and hook up your drives. they all plug right in, you cannot mess up the connections

Not really, the best way to tell is to use it, no damage will come from something NOT being there, usually most PSU are compatible. In saying that though. HP are bad, for using proprietary "Bits" so you have to buy "Theirs" So check that it isn't just some wire that is used, for something. get a Service manual for your unit.

SOURCE: I am installing a new

Basically each connector is made so that it can only go where it should go unless you do some modification or really force the connector in.

All in all you should have one 24pin brick of wires. This is made up of 20pin block plus 4pin block.
If your computer mainboad requires 24pins of power then take the 20pin block and add the 4pin block to it. If not then just use the 20pin block.

Then there is the 4pin CPU power brick. Can only go in one way.
This 4 pin block is not to be confused with the other 4pin block found on the 24pin brick.

Lastly there are 4pin Molex, SATA and stiffy connectors, they can also only go in one way.

If it all fits in then you should be alright.

CPU: 4pin
Mainboard: 20+4pin
Hard drives: Molex or SATA power

The secret: all the wires are oriented (you cannot plug the in backward), and your replacement
power supply must have a connector for each of your peripherals.
Even the connector going to the motherboard is oriented.
Make sure everything on this list has a power connector plugged into it, then
power up the desktop system and compute.

1. motherboard
NOTE: everything below in the list resides in a peripheral bay
2. HDD (hard disk drive) (there may be several)
3. FDD (floppy disk drive)

If you run out of connectors, buy a "Y-connector" at your local "Computer Goodies" store.
As you connect these devices try to utilize proper anti-statis techniques - meaning, if you don't have an anti-static strap to clip onto the Pavilion A810N frame, then be sure to ground yourself
by touching the frame with a forearm or something as you make/unmake the power connections,
while at the same time try to avoid touching the (CMOS-based) IC chips or PC board surfaces.
External drives (incl tape drives) get their own power - not from your 400W Dynex.
Your computer monitor will also gets its own power (from a 120VAC 3-prong CEE cord)

Put on a new power cord wiring diagram

If you need a wiring diagram for this task you should not be doing the work. Please don't dis-assemble the fan, or try to work on it unless you already know what you are doing, you could easily use the wrong cord or not connect the (rather simple I admit) wires correctly.

I bought a power drivers seat from a 1998 dodge ram. I have the wiring out of the truck but need to know where the wires connect. I have a 1997 dodge ram with manual seats and it's not wired for power...

The wiring should be mostly self contained in the seat. All you should need to provide is a power source and a ground. There are many places to tap into a 12V source.
I have linked to a nice wire key for that truck:

Pentair WhisperFlo Wiring Help

If you just bought this then there will be a diagram on the motor nameplate and/or under the terminal cover where you connect the wires. Generally speaking, there are two wires inside the motor that change positions depending on 115 or 230 v connection. If one of the wires is on a post common to one of the line leads, that usually means you have the motor set for 115V. Is that the voltage you are supplying to the motor? If there is no diagram you can make out on the motor, post what brand motor and the motor model number for a diagram.

I need a diagram of the atx pwr connector for an ASUS P4V8X-MX

If you mean power to the devices themselves, the 4-pin connectors coming from the power supply plug in to the drives. The red wire is +5 volts, the yellow wire is +12 volts and the black wires are ground (earthing) connections. IDE hard drives and CD drives use the same connector. SATA drives may have that same connector as well, but most use a different style. SATA-ready power supplies will have 1 or more plugs available. Adapters to switch from the 4-pin IDE plug to SATA type are available for supplies that don't have the right connector.

If you are asking what power pins from the mainboard power supply connector are supplying power to specific controller parts on the mainboard, that kind of detailed information is not available. Mainboards manufacturers do not supply circuit diagrams or repair information. They simply replace any boards that fail while still covered by the warranty, and expect you wil just buy a new one if the warranty has expired.

Much information about ATX boards including the power supply cable pins is found here:

Wiring for Neff Hob-not supplied/no wiring instructions

The details of how to wire the T1213 hob are printed on the base of the hob next to the terminal compartment. For a single cable installation, Neutral is connected to terminals 4 & 5 which should already be linked with a copper link. Terminals 1,2 & 3 should be linked together using the links supplied (hidden in the side of the terminal compartment) and Live is connected to any one of 1,2 or 3. The Earth goes to the terminal beside the cable clamp.

Dear, friend

When connecting IDE devices in your computer, there are a few rules you need to know about.
First, Master and Slave devices are different for the 80-wire cables and the 40-wire cables.
Inside your computer, you generally have two (2) IDE hard drive controller connections. They look this this 99% of the time:

Need wiring diagram for emachines t2200 motherboard

If you are replacing the power supply and it has 4 pin 12v conector and your motherboard doesn't, just disregard the 4 pin plug. The 20 pin conector will supply sufficient power for the processor. Many of the older motherboards did not have a separate 12v supply for the processor.
