Good luck on finding a wiring diagram. Usually those plugs represent the Power Button, the Hard Drive and the other sometimes represents a reset button. If you remove the cover and sit the computer on it's side, take a flashlight so you can see inside at the motherboard. If you look from where the wires come from on the front they usually stick into little prongs on the side of the motherboard. The motherboard will have little written identifiers such as hdd for the hard drive light, pwr for power or power reset, fan for fan, etc.

Also sometimes if you look on the little piece at the end of the red, white and black wires where it plugs into the motherboard prongs, sometimes it will have writing on it as to which one it is.

there was several different versions the connector is all the same wire colors are different main difference was African vehicles had power antenna switch. need to know which part of the world you from? ill show you the right hand drive one.

radio connector pin locations.

You do not need a wiring diagram to replace the fan. TURN OFF POWER.
The fan will have two wires coming from it to two places. Make a little map of that location. There is usually a quick disconnect, you unplug and swap.

There is 2 main cables you have to worry about to feed power to the system. One looks like a big rectangle block with a mess of wires attached. Make sure he is hooked into the system. Then if its an newer unit you will find a plug that has square look to it with just 4 wires attached and should plug in nearby the processor. (only newer units us this) Also if your dealing with the cant turn it on issue make sure to remove all cards off the board like the NIC, Video Card, and Audio Card. I am unsure as to weather or not your system comes with everything onboard or if its stand alone cards. If you still cant power on theres a bigger issue at hand and that maybe that your motherboard has blown.

If it is a bios password, you can reset by using the jumper which should be located near the cmos battery.

You need to track the wires from the case front panel to thier locations: one will be your power switch, one your reset, one hard drive activity light, and one your power light. You want to note and label which light or switch they go to then go to the new motherboards manual and plan which wires need to go where.
the front panel switches : reset and power switch- these are momentary switches so it doesnt matter which way they go.
hard drive activity and power light- these should have a colored wire and a black or white. the colored wire will be your + side.
