CONNECTOR INFORMATION
CAUTION: Not all connectors are serviced. Some
connectors are serviced only with a harness. A typ-
ical example might be the Supplemental Restraint
System connectors. Always check parts availability
before attempting a repair.
IDENTIFICATION
In-line connectors are identified by a number, as
follows:
•
In-line connectors located on the engine com-
partment harness are C100 series numbers.
•
Connectors located on the instrument panel
harness are C200 series numbers.
•
Connectors located on the body harness are
C300 series numbers.
•
Jumper harness connectors are C400 series
numbers.
•
Grounds and ground connectors are identi-
fied with a “G” and follow the same series number-
ing as the in-line connector.
Component connectors are identified by the compo-
nent name instead of a number. Multiple connectors
on a component use a C1, C2, etc. identifier.
LOCATIONS
Section 8W-90 contains connector/ground location
illustrations. The illustrations contain the connector
name (or number)/ground number and component
identification. Connector/ground location charts in
Section 8W-90 reference the illustration number for
components and connectors.
Section 8W-80 shows each connector and the cir-
cuits involved with that connector. The connectors
are identified using the name/number on the Dia-
gram pages.
SPLICE LOCATIONS
Splice Location charts in Section 8W-70 show the
entire splice, and provide references to other sections
the splice serves.
Section 8W-95 contains illustrations that show the
general location of the splices in each harness. The
illustrations show the splice by number, and provide
a written location.

Throughout this group additional important infor-
mation is presented in three ways; Notes, Cautions,
