ok, i am mating this motor(stock 3.8 SC) to a T5 for installation in a 93 Mustang .... Do I want to get the Auto EEC or the Manual EEC? the T5 is obviously not dependent on the EEC, but I don't want to throw a code ... I love 'Lit-Light-Free' dashes .... oh, and should a stock SC cluster fit in a Fox Stang?
