SUBARU LEGACY 1999 Service Repair Manual

F: CONNECTOR SKETCH
IEach connector sketch clearly identifies the
shape and color of a connector as well as terminal
locations. Non-colored connectors are indicated in
natural color.
IWhen more than two types of connector number
are indicated in a connector sketch, it means that
the same type connectors are used.
G: GROUND
Each grounding point can be located easily by
referring to the corresponding wiring harness.
H: DIODE
A symbol is used to indicate a diode.
I: WIRE TRACING ON EXTENDED
WIRING DIAGRAMS
For a wiring diagram extending over at least two
pages, a symbol (consisting of the same charac-
ters with arrows), as shown below, facilitates wire
tracing from one page to the next.
A¨A, B¨B
J: SYMBOLS OF WIRE
CONNECTION AND CROSSING
B6M0750A
K: POWER SUPPLY ROUTING
A symbol is used to indicate the power supply in
each wiring diagram.
ªMB-5º, ªMB-6º, etc., which are used as power sup-
ply symbols throughout the text, correspond with
those shown in the POWER SUPPLY ROUTING in
the wiring diagram.
Accordingly, using the POWER SUPPLY ROUT-
ING and wiring diagrams permits service person-
nel to understand the entire electrical arrangement
of a system.
L: S.M.J.
A symbol is used to indicate the terminal arrange-
ment of the super multiple junction. The S.M.J. is
not shown in respective wiring diagrams but is indi-
cated on the next page.
M: SYMBOLS AND
ABBREVIATIONS
A number of symbols and abbreviations are used
in each wiring diagram to easily identify parts or
circuits.

NOTE:
IAlign the cutout portion of one connector with
that of other before tightening the connecting bolt.
IDo not tighten the bolt excessively since this
may deform the connectors.
