You're trying to use a proprietary part on a different computer.

The plug connector you have was made for a 8(?) contact pin plug connector. (Usually 1 pin is missing, for a 'Key' pin)

The Front Panel header on the mobo you're trying to use it on, has a 10-pin Front Panel header. (Again, 1 pin missing for a Key pin)

You need to separate those individual connectors.
Yeah, I know.

This involves trying to slice/saw them out, and there's Nothing dangerous about that! (Sarcasm)

Moving on............

The connectors in that female plug are female metal terminal connectors. Individual connectors. Example,

http://www.mcmelectronics.com/product/28-9420&utm_medium=Affiliate&ref=cj&utm_campaign=CommissionJunction&utm_source=CommissionJunction

The opening in the front, of course goes over the contact pin, in the Front Panel header on the motherboard.
The back of the connector, shown at the top; is crimped around the insulation of the wire.

The barrel shaped connector slides down into the individual socket hole, in the plug connector.

Looking at the Molex connector, observe the two 'Tangs' that stick out on either side. -> /

When the Molex connector is inserted into the plug connector's socket hole, the Tangs press against the sides of the connector.
When the Molex connector is at the correct depth, in the plug connector socket hole, the Tangs 'pop' out.

They pop out in small depressions, in the sides of the socket hole.
See how they angle towards the back?

If you slide the correct diameter of needle, down in the Front of the plug connector, (And in socket hole), you can depress one tang at a time.

Slides into the socket hole, right next to the Molex connector, and pushes down on the Tang.

Once depressed by the needle, lift up on THAT side a little.
Keeps the tang in a correct position.
Then insert the needle on the other side, and depress that Tang.
You can now remove wire and connector.

Takes a little practice on the first one. Second one goes a little faster, then you're on your way. Just sounds difficult explained so detailed.

With the individual wires, and their connectors; you can plug each wire in where you want. Connect to the contact pin in the Front Panel header, that you wish.

Trying to cut that connector apart, and leave individual amounts of plug for insulation; may prove unfruitful.
Most of the time the material in-between two of those Molex connectors, is very thin.

Maybe one connector will come away with enough material, maybe not. Most will not.

Also you risk slicing your fingers.

Or you could find a plug connector that fits that group of 7-pins, and transpose the wires over to it.

The front of your computer is the Front Panel.
The area of contact pins on the motherboard, that the Main wires connect to, is the Front Panel header.

Main wires being;
Power On switch wires
Power On LED light wires
HarDDrive activity LED light wires
Reset switch wires, IF used

Since you have the manual, out of curiosity are pins 2 and 4 Power On LED?
1 and 3 are HarDDrive activity LED?
5 and 7 are Reset switch?

For additional questions please post back in Comment.

MX46-633V CONNECTING FRONT USB


I believe you're referring to the AOpen MX46-533V

The Front Panel USB header is Blue in color, and located in-between the white No.3 PCI expansion slot, and bottom edge of the motherboard;

http://www.ebay.com/itm/AOpen-Model-MX46-533V-Socket-478-Desktop-System-Motherboard-/130774572519?pt=Motherboards&hash=item1e72c59de7

With the motherboard in the installed position;
5 pins across the Top row, 4 pins across the Bottom row.

Pins across the Top row are numbered EVEN
Pins across the Bottom row are numbered ODD

Starting on the Left side coming across to the Right, Top row;
Pins 2, 4, 6, 8, and 10

Starting on the Left side coming across to the Right,
Bottom row;
Pins 1, 3, 5, and 7

There are TWO USB connectors supported off of this USB front panel header.

For one of the USB front panel connectors;

A) Pin 1 is USB PWR 0
Goes to the VCC contact pin on the USB connector.

B) Pin 3 is USB_FP_P0-
Goes to the D- pin on the USB connector.
(Data - )

C) Pin 5 is USB_FP_P0+
Goes to the D+ pin on the USB connector
(Data +)

D) Pin 7 is Ground (GND)
Goes to the Ground (GND) pin on the USB connector

E) No pin 9

F) Pin 2 is USB PWR 0

For the other Front Panel USB connector;

A) Pin 2 is USB PWR 0
Goes to the VCC pin on the USB connector

B) Pin 4 is USB_FP_P1-
Goes to the D- pin on the USB connector

C) Pin 6 is USB FP P1+
Goes to the D+ pin on the USB connector

D) Pin 8 is GND

E) Pin 8 is USB_FP_OC0
Leave unconnected

This is more information on a standard USB connector pinout,

http://en.wikipedia.org/wiki/USB

( A USB connector, and a USB plug are not wired the same.
The plug is wired backwards from what a connector is.
Otherwise you would have power and signal going to the wrong pins, and burn the USB Front Panel header out on the motherboard )

AOpen MX46-533V motherboard manual, but it is in Japanese.
May be one in English out there.
The Front Panel header pinout, USB header pinout, etc, is easily cross identified,

There are two USB headers on the motherboard for the Front Panel,
JUSB1 and JUSB2. (Junction USB 1 and Junction USB 2)

Looking along the bottom of the motherboard, FROM the Right going towards the Left;

JFP1 header; (Front Panel main wires)
Header with 4 pins on the Top row, and 5 pins on the Bottom row.

JFP2 header; (Dual color Power On LED, and Speaker)
Header with 4 pins on the Top row, {Speaker}, and 3 pins on the Bottom row.

JUSB2 header.

JUSB1 header.

EACH USB header will support TWO USB ports in the Front Panel.
JUSB1 supports two,
JUSB2 supports two.

For each USB header there are 5 pins across the Top, 4 pins across the Bottom.
The pins are numbered EVEN across the Top, and ODD across the Bottom.

Starting from the LEFT side going across to the RIGHT side;
on the TOP row for JUSB2 and JUSB1;
Pins 2, 4, 6, 8 and 10.

Starting from the LEFT side going across to the RIGHT side;
on the BOTTOM row for JUSB1 and JUSB2;
Pins 1, 3, 5, and 7. There is NO pin 9.

A) Pin 2 is VCC
B) Pin 4 is USB1-
C) Pin 6 is USB1+
D) Pin 8 is Ground

E) Pin 10 is USBOC

Pin 10 is N/C -> Not Connected.
It is there, and Pin 9 is not there, to key which way a connector can go on. Only ONE way.

F) Pin 1 is VCC
G) Pin 3 is USB0-
H) Pin 5 is USB0+
I) Pin 7 is Ground

There is NO pin 9.

(The USB technology used is USB 2.0)

http://pinouts.ru/Slots/USB_pinout.shtml

Let's read together,
Under - USB pinout signals;

"USB is a serial bus. It uses 4 shielded wires: two for power (+5v & GND) and two for differential data signals (labeled as D+ and D- in pinout). NRZI (Non Return to Zero Invert) encoding scheme used to send data with a sync field to synchronise the host, and receiver clocks. In USB data cable Data+ and Data- signals are transmitted on a twisted pair. No termination needed. Half-duplex differential signaling helps to combat the effects of electromagnetic noise on longer lines. Contrary to popular belief, D+ and D- operate together; they are not separate simplex connections."

See the USB examples in the link above, where it labels the contact pins?
The MALE connectors are shown on the Left side.
The FEMALE connectors are shown on the Right side.

Your USB ports will be FEMALE, on the Front Panel.
They are also the A style. USB A style. The Top example to the Right.

Just noting the following in case for some reason, the wires coming from those contact pins in the female USB connector, are not color coded correctly;

Even after you have the wires sorted out, as to which contact pins they go to, DOUBLE-check again. Do NOT just go by the color code of the wires.
Why?

You do NOT want to accidentally connect the +5 Volts (VCC), to the Ground!

Explaining further;
You connect the VCC wire, (Red), of the USB port in the Front Panel, to the Ground pin on the USB header on the motherboard.

(Which means the Ground wire of the USB port, (Black), will probably also be connected to the VCC pin, on the USB header of the motherboard)

Zzzzzzap! There goes your front USB ports. Both USB front panel headers on the motherboard, will be DONE!

Make sure!

Going on;
1) VCC or Vcc, goes back relating to Transistor technology.
Just think of it as the Positive, or power wire.
It is.
It is 5 Volts DC.

2) GND is Ground. It's a DC circuit, and you have a Positive, and a Negative, or Ground.

3) USB1-
That is -> Data-

USB0 is for one USB port in the Front Panel.
USB1 is for another USB port in the Front Panel.

[ Each USB header on the motherboard can be connected, to TWO USB ports on the Front Panel.
Therefore for the two JUSB1 and JUSB2, you can connect Four USB ports in the Front Panel ]

Data- on one USB port in the Front Panel, goes to USB0-

Data- on the other USB port in the Front Panel, goes to USB1-

4) Data+
Same thing.
Data+ on one of the USB ports in the Front Panel, goes to USB0+
Data+ on the other USB port in the Front Panel, goes to USB1+

EACH side of JUSB1 and JUSB2, will support one USB port on the Front Panel.
Two sides per JUSB1 and JUSB2 = 4 USB ports on the Front Panel.

For additional questions, or clarification to anything I have stated above, please post in a Comment.

USB 3.0 connectivity to front on GA-Z68AP-D3


Hi,

As you said the board got the front pin connectivity.
All you have to do is buy in any comp shop a front USB and sound socket for the casing.
It is up to you where to put it on the front panel, drill a hole to fit that outlet and use hot glue to fix it in that position.

Hope that helps!

I have the same problem!!!


Diagonally opposite to where you connect your mouse and keyboard, there will be pins for connecting front panel connectors. You can identify them by the names like SPK or Speaker written near them. You just have to match the front panel connectors with that of the pins. USB pins will be near these pins and will be labled as USB5 or USB4 on the motherboard. USB front panel connector can be inserted in only one direction.

WHERE TO INSTALL FRONT USB AND AUDIO CONNECTOR


This should help you. There are 2 USB headers located to the left hand side side of the board looking from the front and down. You should see 9 pins on each.. these provide 4 usb ports to front connector.
The audio connector is located towards the back, and sits just behind and between the PCI and PCI Express slots.
You can download the product guide here.

I'm installing a card reader that has 5 wire connector tto the mb. The old card reader has a 7 wire connector that fits the mb. Its an Asus m2n68-vm. Thanks


These card readers normally fit the auxiliary USB socket on the motherboard. They usually take up all nine pins, four on one row and five on the other with a 10 socket plug. One pin missing on the end of a row.Such card readers have an additional external USB port as well as card reader slots. If it is just a straight five pin plug but with four wires it just fits over one side of the nine pin USB socket on the motherboard. The black wire goes at the end with the missing pin.

Extra USB connection


Hi kalimm,

Your motherboard does in fact have special connectors just for these internal USB ports. These are often called "USB headers".

Based on the manual for the board (which can be found here [LINK]), two of these are located on the bottom edge of the board, below the three PCI slots. These are labeled "USB78" and "USB56" and have nine pins in them, which should match the connector that leads to your case's USB ports. Use of these ports is described in detail on Page "1-25" of the manual and I'd strongly recommend reading through this section to verify that things match up properly.

If you need anything else, please let me know!
