Wiring System
¼ Each connector number shown in the wiring dia-
gram corresponds to that in the wiring harness.
The location of each connector in the actual
vehicle is determined by reading the first character
of the connector (for example, a "F" for F8, "i" for
i16, etc.) and the type of wiring harness.
The first character of each connector number
refers to the area or system of the vehicle.
