I was scared of the Fiesta Zetec SE engine in my build but actually, if you work through the electric spaghetti logically it all makes sense. There are various diagrams on the inter web to help, especially madinventions.com. The diagnostic side is pretty simple - it is cheaper to buy a Bluetooth OBD plug in and a smartphone app than have a diagnostic check at a garage! I managed to sort mine out (humble pilot) so someone with your godlike ability should be able to sort it easily!
