Connector Location
Where the Self-Test connector can be found.
Connector Types
The Code Scanner plugs into the
vehicle “Self-Test” connector which is
located in the engine compartment.
• The EEC-IV computer system (most
1984 & up vehicles) uses TWO test
connectors.
– A large six sided connector.
– A small single wire “pigtail”
connector.
Both of these connectors must be
plugged into the Code Scanner
before use.
• The MCU system (most 1981 – 1983
vehicles) uses ONE test connector.
– A large six sided connector,
identical to the one used with EEC-IV
systems. This connector must be
plugged into the Code Scanner
before use. The MCU system does
NOT use the small “pigtail” connector.
Connector locations
You can tell which computer system is in
your vehicle by noting which connector
type is installed!
The connectors are located in one of six
general areas.
• Near the fire wall (right or left side of
vehicle)
• Near the wheel well (right or left side
of vehicle)
• Near the front corner of the engine
compartment (right or left side of
vehicle)
The connectors are easy to miss – take
your time looking! They are usually gray,
or other dark color, and located close to
a wiring harness. They may be capped
with a plastic cover or shroud labeled
“EEC TEST” or similar wording.
Other Test Connectors
Vehicles made after 1988 may have
additional computer controlled systems
installed, such as Anti-Lock Brakes
(ABS), active suspension and the like.
These systems use a test connector
identical to EEC-IV six sided one. These
systems do NOT use the extra “pigtail”
connector! The Code Scanner is
compatible with most of these systems –
refer to vehicle service manual for
system description and test methods.
