XK8 Range 1999 Introduction
Electrical Guide Format
This Electrical Guide is made up of two major sections. The first section, at the front of the book, provides general information
for and about the use of the book, and information and illustrations to aid in the understanding of the XK8 electrical / electronic
systems, as well as the location and identification of components.
The second section includes the Figures, which are the basis of the book. Each Figure is identified by a Figure Number (i.e.
Fig. 01.1) and Title, and is accompanied by a page of data containing information specific to that Figure.
It is recommended that the user read through the front section of the book to develop a familiarity with the layout of the book
and with the system of symbols and abbreviations used. The Table of Contents on the following pages should help to guide
the user.
Standard Abbreviations
The following abbreviations are used throughout this Electrical Guide:
B+ Battery Voltage
CAN Controller Area Network
COUPE Coupe Vehicles
CONV. Convertible Vehicles
DI Direction Indicator
LH Left-Hand
LHD Left-Hand Drive
N/A Normally Aspirated
NAS North American Specification
RH Right-Hand
RHD Right-Hand Drive
ROW Rest of World
SC Supercharged
SCP Standard Corporate Protocol Network
VIN Vehicle Identification Number
Refer to the vehicle Service Manual for a glossary of standard terms and their abbreviations.
Vehicle Identification Numbers (VIN)
VIN ranges are presented throughout the book in the following manner:
➞
VIN 123456 indicates “up to VIN 123456”; VIN 123456
➞
indicates “from VIN 123456 on”.
XK8 Electrical System Architecture
The XK8 system “architecture” features vehicle multiplexing. Multiplexing allows for greatly simplified wiring harnesses,
while at the same time allowing flexibility in programming market variants. Two data networks are used in the system:
a controller area network (CAN) for the engine, drive train and related systems, and a standard corporate protocol network
(SCP) for the body systems. Any vehicle subsystem depicted on the figures with the CAN or SCP included uses data
derived from the network, or transmits data via the network to achieve control. Messages for both networks are cataloged
in the Appendix of this book. When appropriate, the user will be referred to the Appendix by a note on the Data page.
In addition to the two networks, the XK8 uses a serial data bus (ISO) for diagnostics and for the programming of certain con-
trol modules.
The XK8 uses both power and logic grounds; however, it does not use a common logic ground stud connection as in
previous vehicles.

Figure and Data Page Layout
Figure Pages
Each Figure represents a specific electrical system of the vehicle. The Figures are arranged numerically by system
(01 – Power Distribution, 02 – Ground Distribution, etc.) with variations in the system identified by a numeral following a
decimal point (01.1, 01.2, etc.). Refer to the Table of Contents for a complete list of the Figures.
The Figures 01 – Power Distribution detail the distribution of power to each of the systems. Numbered reference symbols re-
fer the user to a specific Figure and from a specific Figure back to the Power Distribution Figures. This method eliminates the
need to include detailed Power Distribution information on each of the Figures. Similarly, the Figure 02 – Ground Distribution
details the ignition switched ground distribution. The reference symbols are defined on page 12.
Each Figure appears on a right-hand page with a corresponding Data page to the left. The Figure and Data pages are folding
pages. The user must fold out both pages in order to access all the information provided.
Data Pages
The Data page includes information to assist the user in identifying and locating components, connectors and grounds. This
information is supplemented by the illustrations in this front section of the book.
When network data is required for the understanding of a particular circuit, the user is directed to the Appendix.
Where circuits include a Control Module, Pin Out information is provided with values for “active” and “inactive” states. The
values listed are approximately those that can be expected at the control module connector pins with all circuit connections
made and all components connected and fitted. “Active” means a load is applied or a switch is ON; “inactive” means a load is
not applied or a switch is OFF. This information is provided to assist the user in understanding circuit
operation and should be used FOR REFERENCE ONLY.

NOTE: In the examples shown on this page, an ‘X’ is used where a number would appear on an actual Figure.
Reference Symbols
Reference symbols are used for three purposes:
• to allow the user to complete the individual system circuit to power supply or ground
• to refer the user to a related circuit
• to identify control module inputs, outputs and signal grounds
Battery Power Supply
This symbol represents a direct battery power supply and refers the user to Figure 01.1, 01.2 or 01.3.
Ignition Switched Power Supply
This symbol represents ignition switched power supply and refers the user to Figure 01.1, 01.4 or 01.5.
The suffix I indicates auxiliary power. Power is supplied in ignition switch key positions I (AUXILIARY) and II (IGNITION).
The suffix II indicates ignition power. Power is supplied in ignition switch key positions II (IGNITION) and III (ENGINE CRANK).
The suffix E indicates engine management switched power. Power is supplied in ignition switch key positions II (IGNITION) and
III (ENGINE CRANK) under ECM control.
Ignition Switched Ground
This symbol represents an ignition switched ground and refers the user to Figure 02.1.
This symbol without a suffix indicates CRANK. Ground is completed in ignition switch key position III (ENGINE CRANK).
The suffix I indicates auxiliary ground. Ground is completed in ignition switch key positions I (AUXILIARY) and II (IGNITION).
The suffix II indicates ignition ground. Ground is completed in ignition switch key positions II (IGNITION) and III (EN-
GINE CRANK).
Figure Number Reference Flag
This symbol refers the reader to a figure number only. It does not refer to a flag with the same number on a different figure.
As used in Figures 01.1 through 02.1, the reference flag refers the user to a continuation of the circuit. In this instance,
the user matches the number to a Power Supply or Ground symbol to trace the circuit.
In most other cases, it is not necessary to refer to another figure for completion of a circuit, as the reference flags are
used to indicate parallel circuits and circuits that share components. Most of the circuits where this situation occurs are
overlapped to avoid the necessity for cross-referencing to another figure. Exceptions to this rule are instances where
signals are transmitted to or received from other system circuits. When circuits are not overlapped, they are noted by
(CIRCUIT CONTINUED).
BPM Because the Body Processor Module appears numerous times, the abbreviation BPM is used in the reference
flags on Figures 01.2 and 02.1 in order to conserve space.
Control Module Input, Output, Data Link, Signal Ground and Network(s)
Input Output Serial and Encoded Signal Ground (SG) CAN (Network) SCP Network
Communications
These six symbols are employed to assist the user in visualizing the ‘logic’ of circuits containing control modules.
The symbols identify control module input, output, data link, signal ground and network pins. These symbols are also
employed on the corresponding data page.

Code Numbering
When numbering connectors, grounds and splices, Jaguar
Engineering uses a three-position format: AC001, AC002,
etc. Because space is limited in this Electrical Guide, the
codes have been shortened. Thus AC001-001 becomes
AC1-1, AC002-001 becomes AC2-1, etc.

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 identi-
fied by numbers 6 – 10.

HARNESS CODE + GROUND STUD NUMBER + EYELET STUD POSITION (A,B,C) + EYELET DESIGNATION (S,L,R)
Eyelet stud position
There may be up to three eyelets on one stud. A, B and C are used to indicate the position of the eyelet on the stud: A
– first (bottom), B – second (middle), C – third (top).
Eyelet designation
Two eyelet variations are used: a single eyelet and an eyelet pair. The single eyelet has a single ‘leg’, which is identified
by an S; the eyelet pair has two ‘legs’, identified as L (left) or R (right).
SINGLE EYELET EYELET PAIR
