Hi all, Im new to the forum and i am after some information

I have purchased a large quantity of new Ford parts that I plan to sell on ebay, all are direct from Ford all with part numbers. Many of the parts are easy such as alloy wheels and body panels, but others such as ECU's I have not got a clue on. Does anyone know of a way of finding what part fits what car?

I know some of you reading this will think that i should of found this out before but I will be making my money back on the body panels easily and "Who Dares Wins!"

Thanks
