ok adding a/c heaterbox back into a gutted out mav ..got to the vaccuum switch and useing the vacuum diagram provided i really have it all muckered up...why are the vacuum hoses color coded if they dont match the back of the switch..what s up with that? Its a 73 mav and i cant find the right diagram...im thinking that i just ignore the colors on the hoses and go by the way its is on the switch...any ideas
