i have recently purchased a 97 impreza breighton with a 2.2l automatic. but i have no tach. i have seen many other models of impreza of the same year (impreza l, wagon, etc...) with the tach. now my question is this. is my car's wiring pre wired for a tach like hondas do or do i need to repin/add anything? any help is appreciated. thanks, Rick
