Usually the connectors will be marked as in the picture, indicating their usage. CONNECTOR PROBLEM - 07471ce.jpgIf your connectors do not have a label printed on them you can figure out the important ones. You will have a pair of connectors each for the power switch, the reset switch, the power LED and the hard drive LED. 
The two pairs of wires used for the switches are the important ones. They can be identified with a circuit tester or multimeter (Check for resistance/Ohms). When they are pressed, the meter should indicate a connection across the two wires. In the case of the power switch if it's a really old case it will toggle on and off, so watch for the continuity to change when you press it. Otherwise the reset and power switches will only register a connection when pressed, and revert to an open circuit when released. Use your multimeter to identify which pair reacts to which swtich, and label them with some masking tape and a sharpie (or equivalent way). 
As long as you identify these two and connect them correctly you'll be okay. The LEDs are not essential to booting your system and you can figure them out later. LEDs have to be connected the correct way around (usually the white wire is negative), while the switches don't matter which way they are connected as long as it's to the correct two pins. You can connect the LEDs and see which ones light up on your panel to determine which is connected where. If your power-on LED lights when there's hard drive activity, then you know that the connector plugged into the pins for HDD LED is the wires for the power LED, and so forth.

Hope this helps.

Replace RJ45 connector

You have to cut off the bad connector, strip the outer sheath about an inch down, untwist the wire pairs and put the wires in the correct slot on a new rj45 connector and use a crimping tool to crimp it. You could also buy a new cable for a couple dollars on

How to connect the front penal with motherboard

To connect the front panel of your case with your motherboard, it is quite easy.

If you have the motherboard manual, I will help you on connecting the cables to the motherboard.

In summary, the pins or connectors for the front panel are on the same spot of the motherboard.
If you don't have the manual, check on the motherboard, THere are like 8 or 10 pairs of pins which are labeled.

The speaker cable is a 4 pin conector. See the speaker's pin on the motherboard.
The Power cable will fit into a 2 pin connector.
The HDD Cable as well
The reset. too..

The colored cable is always +, the black cable is always -
The + usually goes on the first pin of the assigned connector.

For example: motherboard connector is:

The cables goes on the Jumpers area.

You will see somthing like this:

Hope that helps

There is 4 pair cat5E caple with one pair defective, how can u trace the defective wires. Are you capable of putting connectors on a faulty cate5E cable, having 2 wires defective out of the 8.

To use 8 wires cable for 100BaseTX connection only four wires are used, pin 1,2,3 and 6. You can find defective wires by using wirescope which can detect which wire has problems. If these two wires are not one of these I had mentioned according to standards 568A or B (it depends of the rest of the network) then you can use it if not then take care wher to put these bad wires but not on pins 1,2,3 or 6. Take care to document this. The best solution is to replace this bad cable with good one and do everything according to standard procedure.

Not sure if I have one installed. Which of the 3 slots should it be in. What are the 2 cards I have installed now?

> not sure if have one installed.

One what?

Take a look at the connectors on the 2 cards.

Is one connector a VGA "video-output" connector?
If so, it's a video-card.

Is one connector a pair of sockets, with 4 gold wires per socket?
If so, it's a modem.

Is one connector a single socket, with 8 gold wires?
If so, it's a network adapter.

Is one connector an oval "female", with 25 holes?
If so, it's a parallel-port adapter, for an older-style printer.

Is one connector a thin slot (or a pair of thin slots) ?
If so, it's a USB adapter, for connecting USB devices.

Is one connector a standard coax cable (such as on the back of your TV) ?
If so, it's a TV-input card, to turn your computer into a TV-receiver.

What wiring to use to connect our RJ45 connectors for computer

The order you give is right. Ethernet uses the orange pair and the green pair (1, 2, 3, 6). Phone uses the blue pair (4, 5).

Crossover cable

Unless you have the proper cable crimper for making network cables, it would be faster and easier to just hop down to your local computer store, or even Walmart/Target and buy one.

If you do have the tool and want to make one from scratch, follow the steps listed below.

NOTE: Only two pairs of wires in the eight-pin RJ-45 connector are used to carry Ethernet signals. Both 10BASE-T and 100BASE-T use the same pins, a crossover cable made for one will also work with the other.

*Note: Even though pins 4,5,7, and 8 are not used, it is mandatory that they be present in the cable.

The combination for the pins is:

Connector 1: Pin1 to Connector 2: Pin3
Connector 1: Pin2 to Connector 2: Pin6
Connector 1: Pin3 to Connector 2: Pin1
Connector 1: Pin6 to Connector 2: Pin2

Hi Fi Speaker

Might be your amp dying on you? Overheating and giving up in the end. Open it up and check the output stage. Depending on make/model it's using power modules or a few transistors per channel. The modules are little black boxes screwed onto a heatsink as are the transistors, only a bit smaller and usually two per channel. When one of the pairs feels warmer than the other the problem lies there. Best to bring it into a repair shop.
