Im assuming that by dizzy you mean starter? the starter is wired as follows battery to bat terminal and then i have a brown colr wire wich i dont know where it leads but its there then its spliced with a diode between the brown and in comes the r cable from the cab on the other side of diode i wouldnt know why you need the diode but in the starter instructions it tells me to use it if the strter doesnt have a R terminal this diode leads to the Plus side of the CoiL
