WIRING DIAGRAMS

WIRING DIAGRAM INFORMATION

Wire Color Codes

Wire traces on wiring diagrams are labeled with alpha codes.
Refer to 

Table B-4

.

For Solid Color Wires: See 

Figure B-16

. The alpha code

identifies wire color (3).

For Striped Wires: The code is written with a slash (/) between
the solid color code and the stripe code (4). For example, a
trace labeled GN / Y is a green wire with a yellow stripe.

Wiring Diagram Symbols

See 

Figure B-16

. On wiring diagrams and in service/repair

instructions, connectors are identified by a number in brackets
(1). The letter (2) inside the brackets identifies whether the
housing is a socket or pin housing.

A=Pin: The letter A after a connector number and the pin
symbol (6) identifies a pin housing.

B=Socket: The letter B after a connector number and the
socket symbol (5) identifies a socket housing.

Other symbols found on the wiring diagrams include the symbol
for a diode (7), a symbol for a wire-to-wire connection (8), a
symbol that verifies that no connection (9) between two wire
traces exists and a symbol identifying two wires that are twisted
together (10).
