-=-WIRING DIAGRAMS___ INTRODUC110NINTRODUCTIONThe wiring diagrams in this section are presented in a continuous rail type format. All the circuits whichmake up the main wiring diagram for a particular model are positioned side by side in three rows one abovethe other and are connected to each other by a common earth line representing the vehicle chassis.The key to each main wiring diagram includes grid references which give the location of components on thediagram. Please note that the location of components on the diagrams bears no relation to their location onthe vehicle.

, ~~ ~. . . .~Interconnections from one circuit to another are identified by a 'num'ber within a triangle. Outputs are shownwith the lead connected to the base of the triangle and inputs are .shown with the lead connected to theapex. A chart giving all the grid references where each connection .point ,appears together with anysupplementary diagrams which contain that connection point is. in.cllAded.

''':'':Earth points are shown as a numbered earth symbol in a box,,"'th. number identifies the position of the earthpoint on the vehicle and relates to an illustration of the vehicle,included in the section. A componentwithout a number identification on its earth poin,t is either earthed through its fixing or through a cablewhich is earthed adjacent to it. ,";,'
