Fuse block—Junction box (J/B)
Fuse block—Junction box (J/B) connector number is shown in the
Reference Area of the wiring diagram. For connector terminal and
fuse arrangement, refer to the“FUSE BLOCK—Junction Box
(J/B)”electrical reference page at the end of the manual.
Fuse and fusible link box
For fuse arrangement in the fuse and fusible link box, refer to the
“FUSE AND FUSIBLE LINK BOX”electrical reference page at the
end of the manual.
Electrical units
Electrical unit connector symbols are shown in the Connector Area
of the wiring diagram.
However, when there is not enough space to show the connector
terminal arrangement in the Connector Area of the wiring diagram,
the electrical unit connector number is shown in the Reference
Area of the wiring diagram. For electrical unit connector terminal
arrangement, refer to the“ELECTRICAL UNITS”electrical refer-
ence page at the end of the manual. Most of the electrical unit
connectors on this page are shown from the harness side of the
connector.
Joint connector
Joint connector symbols are shown in the connector area of the
wiring diagram. For connector internal wiring layout and joint con-
nector terminal arrangement, refer to the“JOINT CONNECTOR
(J/C)”electrical reference page at the end of the manual.
