Electrical Component Location and Wiring Information in::m3^?
DB7 Electrical Component Location and
Wiring Information
Thefol lowing pages contains electrical component
location and electrical wiring diagrams.
Component Index
The following list details all of the functional
electrical components of the DB7. The list is given
in alphabetical order with component location and
wiring diagram references for each component.
Component Location on the vehicle
To locate a component on the veh
icie,
find its name
in the component index and note the component
location reference.
The component location reference gives the figure
number and item number for each component so
that you can find the component on the following
location diagrams and in the car.
Component Location on the Wiring Diagrams
The wiring diagram reference gives the wiring
diagram number and the location coordinates so
that you can locate the component and its wiring
on the wiring diagrams.
Wiring Diagrams
Each diagram covers a complete loom or section of
a major loom.
Continuations of a loom on another sheet and
connections to other looms are indicated by the
continuation arrow »* and the Sheet Number and
Co-Ordinateswherethecontinuation or connection
is located.
Each connector is illustrated with an end view of
the mating face of the connector. A table beside
each connector gives the pin number, wire colour
and destination of each wire.
Wire Colours
The following key is used to denote wire colours in
the connector wiring tables
B = Black P = Purple G = Green
K = Pink S = Slate LG = Light Green
N = Brown W = White O = Orange
R = Red U = Blue Y = Yellow
Wire Splices
Many wire runs are spliced within the loom
wrapping and additional information is required to
aid in fault analysis. All splices are noted on the
wiring diagrams (e.g. SPL1 = Splice 1). On the
facing page for each wiring diagram, a splice list
gives the splice number and the wire colours and
destinations for each wire coming from the splice.
