Depending on the motherboard you can find the manual in a downloadable format on the website as long as you have the manufacturer/model name. or just do a quick google search.
Connecting things in the wrong place can cause short circuits which will damage your hardware. Please take precaution.
Thats the thing I only know its a h67 motherboard and it says American megatrends on it and I saw a ASUS logo on it one time
