What type of light is it? Like an actual grow light MH or a MH that he nabbed off a building or something? If its an actual grow light than it wont be hard to replace the cord seeing as it plugs into the hood. If its a flood light that he got u, then just connect the colors, electricity is not hard, just understand it. If the colors are different, green is always ground, white is always positive, have fun.
