my brother owns a first gen lightning and we decided to order a 408 from coast high performance....so...we needed to do the conversion to mass air flow from the stock speed density...bro ended up ordering the conversion kit from mass-air .com...it comes with a computer to make the transmission work....everything having to do with the engine is done...but we cant figure out how that computer wires up..the truck according to what hes told me is only running on second and third gear it wont use first or overdrive.anyone here ever done this conversion...and if so... can some one point me in the right direction to see what needs to be done to finish it up.....any help is greatly appreciated...thanx
