position in the short terminal may be connected to
a wire harness from a different part.)
Wire harness sharing the same short terminal
grouping have the same color. T :Indicates the reference page showing the position on the vehicle of Relay Block Connectors in the system
circuit.
Example: Connector 1º is described on page 16 on this manual and is installed on the left side of the
instrument panel.
U :Indicates the reference page showing the position on the vehicle of J/B and Wire Harness in the system
circuit.
Example: Connector 3Bºconnects the Cowl Wire and J/B No. 3. It is described on page 14 of this manual,
and is installed on the instrument panel left side.
V :Indicates the reference page describing the wiring harness and wiring harness connector (the female wiring
