when the vehicle model, engine type, or specification is different.
[J] : Indicates a shielded cable.

HINT :
Junction connector in this manual include a short terminal which is
connected to a number of wire harnesses. Always perform inspection
with the short terminal installed. (When installing the wire harnesses,
the harnesses can be connected to any position within the short
terminal grouping. Accordingly, in other vehicles, the same 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.
