Accessory Delay Relay: Diagram Information and Instructions
All wiring connections between components are shown exactly as they exist in the vehicles. It is important to realize, however, that no attempt has
been made on the diagrams to represent components and wiring as they physically appear on the vehicle. For example, a 4-foot length of wire is
treated no differency in a diagram from one that is only a few inches long. Furthermore, to aid in understanding electrical (electronic) operation,
wiring inside complicated components has been simplified.
Complete Circuit Operation
Each circuit is shown completely and independently in one set. Other components that are connected to the circuits may not be shown unless they
influence the circuit operation.
Current Flow (1)
Each set normally starts with the component that powers the circuit, such as a fuse or the ignition switch. Current flow is shown from the power source
at the top of the diagram to ground at the bottom of the diagram. A full representation of the power supply of a fuse or the power distribution from a
fuse to various components is given in the Power and Ground Distribution Diagrams. Full representation of the ground connections are shown in the
Power and Ground Distribution Diagrams.
Switch Positions (2)
Within a diagram, all switches, sensors and relays are shown "at rest" (ignition switch OFF).
Splices directly connecting to the power distribution are best represented on the power distribution diagram in the Power and Ground Distribution
Diagrams. Splices connected to grounds can be seen completely in the Power and Ground Distribution Diagrams. For all other splices, a reference is
