4. How to Use Wiring Diagram
B6M0213A
A: RELAY
A symbol used to indicate a relay.
B: CONNECTOR-1
The sketch of the connector indicates the one-
pole types.
C: WIRING CONNECTION
Some wiring diagrams are indicated in foldouts
for convenience. Wiring destinations are indi-
cated where necessary by corresponding sym-
bols (as when two pages are needed for clear
indication).
D: FUSE No. & RATING
The“FUSE No. & RATING”corresponds that
used in the fuse box (main fuse box, and joint
box).
E: CONNECTOR-2
1. Each connector is indicated by a symbol.
2. Each terminal number is indicated in the cor-
responding wiring diagram in an abbreviated
form.
3. For example, terminal number“C2”refers to
No. 2 terminal of connector (C:F41) shown in
the connector sketch.
