WIRE ASSIGNMENTS



Red: + 5V / Voltage + / VCC
White: D - / Data - / USB -
Green: D + / Data + / USB +
Black: GND / Voltage - / Ground
Black: S-GND / Over Current / Shielding

The S-GND wire is fatter and can be easily recognized. The connection of S-GND wire to the header pin is optional.

HEADER CONNECTION GUIDES


Diagram 1: On most motherboards, the USB header/pin-out consists of 9 pins arranged in 2 rows, which allows for 2 USB connections (i.e. USB1 and USB2). Normally, the pins for USB1 and USB2 are in seperate rows.
Diagram 2: Simply plug the connector onto the 5-pins row, and make sure that the pin assignments and wire assignments are matched correctly.
Diagram 3: Alternatively, you can plug the connector onto the 4-pins row, and leave the S-GND wire unconnected.
You might have to rearrange the wires to match with the pin assignments, or change the header connector if necessary, depending on the layout of the USB header.
On some motherboards, there is a NC pin in the USB header. You can connect the S-GND wire onto this pin. NC simply means "no connection" and NC pin is an "empty" pin.
2X5 PINS HEADER
Refer to the diagram below, for 2x5 pins header, simply plug the connector onto one row of the pins, and always make sure that pin assignments and wire assignments are matched correctly. You might have to rearrange the wires if necessary.


2X4 PINS HEADER
Refer to the diagram below, for 2x4 pins header, simply plug the connector onto one row of the pins. Please note that there is no S-GND pin in this header. You can leave the S-GND wire unconnected. You might have to rearrange the wires if necessary, in such that the wire assignments and pins assignments are matched correctly.



ACTIVE PINS NOT IN THE SAME ROW

On some motherboards, the 4 active pins are not located in the same row, as shown in the example below:

To connect to this type of USB header, you need to change the header connector to 2x5. Simply rearrange the wires within the 2x5 connector to match with the pin assignments. If the green wire is connected to the USB2+ pin, the white wire must be connected to the USB2- pin. The red wire can be connected to any +5V pin, and the black (GND) wire to any GND pin. If there is no S-GND pin provided, you can leave the S-GND wire unconnected.




hope it helps

How do I connect the front usb wires to my fic c51g motherboard header?


How to Install Front USB by Connecting Front USB Ports to a Motherboard?In order to have front mounted USB you must have 3 things.
  1. A case with USB ports in the front of it.
  2. A motherboard that supports front USB (usually)
  3. Appropriate wiring between the USB port and the motherboard
A case can support front USB in two ways: via a pass thru connection, or via a port to header connection. The former, pass thru connection, is compatible with all motherboards that have USB ports. Pass thru front USB Pass thru front USB works by having the ports on the front of the case connect to either a standard USB cable, or a fairly small rounded cable. The cable goes from the front of the case to a special slot cover with either a hole (for the standard USB cable) or a special connector for the rounded cable. If the pass thru USB had a standard cable, then you would simply plug the standard cable into one of your back USB ports. If it had a rounded cable, then you have a secondary attachment with something that looks like an old style SCSI connector. The attachment plugs into both the slot cover, and the back USB ports. The draw back of pass thru front USB is that you lose the ports in the back.

Many 3rd party devices that add front USB to a system use the pass thru system. A good example is this now discontinued Front IO panel
directron_1721_2292726
Front USB via a Port to Header connection In order to hook up a Port to Header connection you have to make sure that the wires from your port will connect to your motherboard's header. To do this you need to know what header you have, and what type of connector you have on the wires. You'll find information on both below.

Almost all motherboards these days have a USB header. Due to size and cost restraints many motherboards only have 2 USB ports on their back panel, but often they can actually support more then 2 USB ports. They will typically support additional ports via the use of a USB header. A USB header is either a single or double row of header pins on the motherboard that can be used to add additional USB ports to a computer via the use of an appropriate set of header connectors, wires, and a USB port. Each pin on the header corresponds to a wire inside a USB cable. These pins must be clearly marked so that you can hook them up to the wiring correctly. There are 2 common layouts for a USB header.

Intel Standard USB header Layout: (used by over 90% of motherboards)

instusb1a.jpg

Gigabyte Style USB header Layout: (used most commonly on Gigabyte brand motherboards)

instusb2b

Now that we know the types of headers we have to take a moment to understand the USB wiring. Understanding the wires First off: All USB cables have 5 wires. 4 of these wires are actively used. Here's a reference from the official USB standard.

instusb3

On a front mounted USB port you'll have either the first 4 wires connected to properly colored wires (red for power, white/orange d-, green/yellow d+, black for ground) or all five wires attached to the port (same as the former, but one extra black wire). Now where it gets tricky is how to attach each of those wires to corresponding pins on the motherboard.

The wires are "tailed" (attached to a header connector) using any one of a number of different types of connectors. Below you'll find a list of the common ones.

Common USB case header connectors 4 joined pins + 1 extra ground.
usbheader

Compatibility: Compatible with both header arrangements because of the extra ground. May not work with some odd arrangements To hook up carefully match each pin. For the Intel hookup you'll have the extra ground wire not attached to anything. For the Gigabyte hookup you'll have the extra ground hooked to ground pin on the motherboard, and the standard ground jumper will be over the missing pin on the header.

All pins separated

instusb6

Compatibility: Compatible with every header. If all the pins are separated the only real issue is lining up the pins with the appropriate places on your header. It should be compatible with all headers. Just make sure you read the writing on each individual connector. Please check the troubleshooting info at the end of the article for important information on this configuration

Power and Ground separate, d-, d+ joined Lian-Li style

Compatibility: Compatible with all common headers. This sort of arrangement is common to almost all Lian-Li cases. Make sure that you get the wires connected to your header in the proper order. If you find that the port does not function the most common cause is accidental reverse of the d-,d+. Try switching it.

All pins joined Intel style easy connector

usbinst4
making the Connection Once you know what type of header you have, and what type of connector you have on the wiring, you need to connect the two of them. In order to do this, you must first figure out what pin goes with what part of the connector. To do this, you should first consult your motherboard manual. Below you'll find an excerpt from a fairly recent motherboard manual for the Asus A7M266 motherboard. It's typical of a motherboard manual for a board using the Intel standard USB header.

instusb5

The first thing you'll probably notice is that the wiring from your case and the names of the pins might not quite match up name wise. This is a common problem. Motherboard makers and case makers really haven't decided on what to call each pin. Here's a rough list of names.

Power may be called: P, VCC, USB Power, Power, and PUSB. On wiring it's always red. Ground may be called: G, GND, Ground, and GUSB. D- may be called: USB-, USBP-, D-, or just -. D+ may be called: USB+, USBP+, D+, or just +.

To complicate things a bit more you'll probably notice that there's a number before each one. Take a look at the picture above from the USB hookup diagram for the A7M266.

You'll see that Asus decided to number the middle pins. On the first row (starting with pin 1, and marked with a 1) you'll find that they list D- as USBP2-, and D+ as USBP2+. The number 2 tells you a few things. First off: It's the 3rd USB port on the motherboard (they started numbering at 0), second it tells you that that D- and D+ must be used for the same port. Case manufacturers are just as likely to number their ports differently.

Take a look once again at the 4-pin joined picture: usbheader

Notice that you're D-'s have either a 1 or a 2 on them. These also tell you that they are part of the same USB port. (Remember, 1 port has 4 required wires). The numbering on the connector and the numbering on the header doesn't have to match.

To connect everything grab the following connectors: a same number D pair, (D-, D+), 1 power, and one ground. If your power and ground are numbered make sure all 4 are the same number.

Tip: Most cases that use all separated pins will bundle these together for you to make it easier.

Now, take your Power, D-, D+, and Ground and line the connector up with the appropriate 4 header pins on your motherboard. The header pins will be in a row under the Intel style, and in the Gigabyte style it will either be a row of 1 pin, a gap, and then 3 pins, or 3 pins, a gap, and then 1 pin. Press the connector down over the header pin and make sure it's firmly attached. Once you have done this go back and grab another set of connector wires (Power, D-, D+, Ground), and hook up your second front USB port. If your case has more then 2 front USB ports, and your motherboard has more then one front USB headers, then repeat the above as necessary.

Example: If you were hooking up the front USB on a A7M266, on a case with the pictured 4-pin joined connector type then: VCC lines up with USB Power, USBP2- lines up with USB1-, USBP2+ lines up with USB1+, and GND lines up with GND. For port 2, VCC lines up with USB Power, USBP3- lines up with USB2-, USBP3+ lines up with USB2+, and GND lines up with GND.

Of The 4 Connections On The Motherboard Is A Specific Pin Connection Critical Regarding Which One The Internal Main Hardrive Connects To?


According to specifications listed on Sony Vaio Support, the Vaio VGC-RA840G desktop computer uses a SATA harddrive.

http://esupport.sony.com/US/perl/model-documents.pl?mdl=VGCRA840G

[Left-click on Marketing Specifications]

If you have four SATA headers on your motherboard, you can plug your SATA harddrive into any one of them.

The beauty of SATA is that once you plug into any SATA header, BIOS will find the harddrive. Doesn't matter which SATA connector. (Connector on a motherboard is referred to as a Header)

1994 Bronco Egr valve doesnt fit into new ****** headers


They sold you a set of headers that don't accommodate the EGR valve line. You can buy headers that have the bung welded into them for the connection. If you do not connect the EGR then you exhaust gas temps will run high and pinging will likely be the result. Excessive preignition can cause valve and piston damage. The lack of the EGR valve may cause you to not pass your states emissions test. I would purchase a set of headers that have the hook up on them. Try Gibson headers. They sell these.

Location firewire input port


There isn't one on the back panel. You must connect the USB/1394 bracket that's included with the board to an empty slot on the rear of the computer and hook up its connectors INSIDE the computer to the appropriate headers on the motherboard: the purple firewire connector would connect to the purple header (DUH!) on the RIGHT in the pic below, it's a DOUBLE firewire header and it's the only place this bracket will fit. The yellow USB connector would go to any open USB header on the board (guess what color...) Very simple, really.

1f72ff6.jpg ed2998b.jpg

Optionally if your computer case has a built-in firewire port on the FRONT panel, as most do nowadays, you can connect that to the appropriate header on the board using the already-installed cable that's connected to that front firewire port (connect this one to the purple header on the LEFT, it's just a SINGLE firewire port.)
However, this header's pins will NOT match up properly with almost all case's front-panel firewire connectors. You would most likely have to switch around 2 or 3 of the little wires that go into the connector so that it matches the motherboard's pin-out.

It's clearly labled in the manual for the board, and isn't really all that difficult to switch the wires around, but I would recommend just going with the first option and connect the included bracket to the back since it was designed to go with this board and requires no modification.

Problem with microphone


most of the old motherboards dont support the audio and mic port to work both in back side(back panel header) and front side (front panel header)simultaneously...

most of the old motherboards dont support multi streaming so you cant make both the back panel header and front panel header to work at a time ie i mean you cant connect both panel header at a time ...

you can just refer to your motherboard manual for the detailed information about it ..

in your motherboard if there is any option to connect the front panel header to the motherboard other than the back panel header you can connect it to that the detailed pin information will be given in the motherboard manual ..

if you dont have the option in the motherboard to connect the front panel header seperately then you must remove the pins connected from the back panel header and you must insert the front panel header pins .
this will disable your back panel audio ,mic,linein functionalities but you will be able to connect in front panel header , this front panel header will work ..

if the motherboard is not compatible then the system assembler will leave the front panel wires not connecting to motherboard ..

like this only one panel can work at a time ,
but in the latest motherboards the multi streaming technology has been introduced so both the panels can work at a time and can play different audio on 2 different panels ...
