Using a spare molex connector you will need to determine if you want to use 12v or 5v then you will need to install a current limiting resistor in series with the LED's.

Molex conector is as follows
yellow= 12v
both blacks=ground
red=5v

depending on how many LED's and what colour LED's, the resistor you use may differ

This may also help with calculating the resistor value
