CONNECTORS
Connectors shown in the diagrams are identified using
the international standard arrows for male and female
terminals (Fig. 4). A connector identifier is placed next to
the arrows to indicate the connector number (Fig. 4).
For viewing connector pin outs, with two terminals or
greater, refer to section 8W-80. This section identifies
the connector by number and provides terminal
numbering, circuit identification, wire colors and
functions.
All connectors are viewed from the terminal end unless
otherwise specified. To find the connector location in the
vehicle, refer to section 8W-90. This section uses the
connector identification number from the wiring diagrams
to provide a figure number reference.

TAKE OUTS
Figure 4 – Electrostatic Discharge Symbol
The abbreviation T/O is used in the component location
section to indicate a point in which the wiring harness
branches out to a component.

ELECTROSTATIC DISCHARGE (ESD)

SENSITIVE DEVICES
All ESD sensitive components are solid state and a
symbol (Fig. 5) is used to indicate this. When handling
any component with this symbol, comply with the
following procedures to reduce the possibility of
electrostatic charge buildup on the body and inadvertent Figure 5 – Electrostatic Discharge Symbol
discharge into the component. If it is not known whether
the part is ESD sensitive, assume that it is.

1) Always touch a known ground before handling the

part. This should be repeated while handling the part
and more frequently after sliding across a seat,
sitting down from a standing position or walking a
distance.
2) Avoid touching electrical terminals of the part, unless
instructed to do so by a written diagnostic
procedure.
3) When using a voltmeter, be sure to connect the
ground lead first.
4) Do not remove the part from its protective packing
until it is time to install the part.
5) Before removing the part from its package, ground
the package to a known good ground on the vehicle.
