Harness Component Numbers

Connectors





HARNESS CODE + CONNECTOR NUMBER + PIN NUMBER
EXAMPLE: FC7-24 (pin number is separated by a dash)

Where the pin number differs from LHD to RHD, the connector number will be further identified by (LHD) or (RHD).

Splices






HARNESS CODE + S (SPLICE) + SPLICE NUMBER
EXAMPLE: RHS3 (no dash is used)

NOTE: In order to avoid unnecessary circuit complication, multiple splices (more than two wires) within components, in wires leading from input components to multiple circuits and in harness "ground" sides, are simplified so as not to show wires from other circuits.

Splice Headers






Three non-serviceable splice headers are used in the system harness. Splice headers are depicted as components and identified by a connector number within the component. The splice header number appears at the upper left hand corner; pin numbers appear adjacent to each pin.

Diodes





Harness diodes occur at connectors and are depicted as components and identified by a connector number.

Relay Connectors






Relay connector numbers are shown within the relay. The connector number is shown in the upper portion of the relay; the pin (terminal) number is shown adjacent to the pin. Certain relays are paired and share a modular connector. In this instance, the connector number remains the same for both relays while the pin numbers of the second relay are identified by numbers 6 - 10.

Grounds
HARNESS CODE + GROUND EYELET NUMBER + EYELET DESIGNATION (SLR)

Eyelet designation






Two eyelet variations are used: a single eyelet and an eyelet pair. The single eyelet has a single "leg" and can be identified by the absence of a suffix. The eyelet pair has two "legs," identified by the suffix L (left) or R (right).






Where the ground designation differs from LHD to RHD, the RHD ground is shown in parentheses. If the ground designation is the same for LHD and RHD, only one ground designation is used.

NOTE: The XJ Series ground studs are not identified by code. Therefore, multiple eyelets with different harness codes may be connected to a ground stud.


SCP Network





Due to circuit complexity and because space is limited, the SCP Network is, in most cases, shown as a broken grey line indicating that there is network communication between the depicted control modules. Refer to Fig. 19.1 for circuit details. Electrical Diagrams
