My son pulled off the following wires off the motherboard when i was installing a new drive.
power LED +
power LED -
I DO NOT HAVE THE MOTHERBOARD diagram to re-connect the leads.

SiS965L is a chipset designation, not a motherboard model number. That said, most motherboards do label the header pins for the front panel connections on the motherboard, though they are a bit small and sometimes are not adjacent to the pins themselves. The Power Switch and Reset Switch pins are not polarized, and when you determine which they are, the connector plug can be installed on them either way. The Power LED and HDD LEDs ARE polarized. The positive pin is marked with a "+" sign and the Green wore of the Power LED and the Red wire of the HDD LED must be on the "+" terminal.
Not to much information from you . Here is a E-Machine assembly for the motherboard .
The power switch is a 2-wire connection to the Motherboard. The 2 pins on the motherboard it connects to will be labeled something like PW. The polarity on it doesn't matter. There will also be a power LED connection. Usually those wires are green and black. Green is positive. There's also a hard drive activity LED with (usually) red and black wires. Red is positive. Hopefully that polarity will be marked on the motherboard. If not, try it one way and if the LED doesn't light up, try it the other way. The power (green) LED should be on whenever the PC is on. The hard drive (red) LED will be on whenever the drive is being accessed.
There might be pins on the motherboard for reset. Some computers don't have a reset button. In that case you wouldn't connect anything to it. If your case does have a reset button then connect the wires to the reset pins on the motherboard. Polarity doesn't matter for that.
You will need the user's manual for your machine to make sure that you are hooking the wires up correctly. However, most motherboards label these connections directly on the motherboard next to their pins. Look for an area on the mother motherboard with two rows of six to eight pins. Next to them you should labels such as PWR_SW (power switch), RST_SW (reset switch), HDD_LED, PWR_LED, etc. You won't mess anything up connecting something to the wrong pins, but it isn't that hard to figure out as the wires are usually labeled in the same manner as the pins. So HDD_LED would plug into the HDD_LED pins, PWR_SW to PWR_SW, etc.
You shouldread themotherboard manual,for cabling: 1. Power SW 2. Reset SW 3. HDD led 4. Power led - and power led + 5. Speaker Cablingscheme,alsowrittenon the motherboard.
If thePowerSWnotinstalledthe switch ondoes not work. If theResetSWnotinstalled the switch resetdoes not work If theHDD lednot installedthe harddrivelight(red)is not lit If thePower led(+/-) notinstalled thepower light(yellow)is not lit If theSpeakers arenot installed,whenthe computer is onthe beep soundis not heard.
Use a magnifying glass to read the mobo print by the wire connectors. You should be able to spot something. The on/off (power) button will go to the connector marked PWR or PW_SW or similar. The LEDS will be (you should have 2 at least), one going to power led which should be named something like POWER, PWR_LED or PW_LED. And the other should be something like HD_LED or similar. You might have to follow the wire from the case's front bezel if it's purpose isn't marked on it's connector, to figure which LED is hard drive and power. You might have a reset switch on that case, and that would go to RES_SW or RESET or similar.
LED's will not work if attached backwards. You need to connect the positive lead from the case to the positive pin on the motherboard, and the same with the negative. Unfortunately, the case connector almost never has the positive and negative labeled. The +/- is also hard to spot on the mobo. Fortunately, attaching them backwards will usually not cause any damage; the LED just won't work. The LED will usually have the colored wires (blue, green, yellow, red, orange) as the positive, and a 2nd black or white wire which will be the negative. NOT always though.
The reset switch has no polarity, so that won't matter which way it's connected.
After you get it right, make a map of the pin connections and sock it away in case you need to remove/replace the mobo again in the future. I got a map of each of my computers, as they are all different (mobo's), though the cases are the same brand.
The leads on the wires are usually grouped into two's or three's and will have some letters stamped on them (i.e., pwr for power, pwr led for power LED, etc.), on the motherboard, there will be a block of connectors for these to plug on to and they'll usually have the same lettering as well. Just match the leads to the block and you should be good to go.
there is a possibility that you may have pulled off the power switch, to motherboard Connector.
This will be at the bottom right hand-side of the Motherboard.
You should have a 2 cable connector for. pwr/sw Power Switch. hdd/led Hard-Drive led. rst/sw reset Switch.
Check those First. if you didn,t remove the power lead, before attempting any work. you may have arced a current, and damaged the motherboard Or PSU. check the Fuse In The Actual plug lead. to determine the actual power Switch, without a multi-meter. remove the power lead, from the Computer. remove the power/sw connector From motherboard, And Bridge the power/sw with A plastic jumper Block. then replace power lead, and should boot up. If it does the fault is the actual power switch faulty.
