Wiring Harnesses
The wiring in the coach is provided in modular replaceable harnesses. The harness contains several spare
wires for replacements for broken wires or for the operator to add features some time after delivery of
the coaches. If only one or two wires are broken or damaged, the spare wires can be used to replace the
damaged circuits. If the entire harness is damaged, however, it should be replaced.
The harnesses are connected by multi-pin connectors. This feature permits service or replacement with-
out the necessity of disturbing adjacent harnesses. Troubleshooting circuits within the harness is facili-
tated by the use of this type of connector. The pin numbers at each connector for the circuit are shown in
the Electrical Schematics Manual .
Wiring Harness Connectors
The following types of connectors are used in the coach:
Terminal Type Connectors
Terminal type connectors are used at the end of wires extending from harnesses to make connections to
battery and ground connections, or to post type junction blocks, and to connect individual switches, such
as those in the rear run box. Terminal type connectors are attached to the unit with a screw or nut, or the
terminal is pushed into a mating terminal on the unit being supplied with current.
Blade Type Connectors
Single and multiple blade type connectors are attached to the ends of wires extending from the harnesses
and are used for making connections to individual units such as horns, relays, and switches on the dash
panels and electrical control panels.
• To remove a wire and terminal from the connector, insert a thin blade screwdriver into the open
end of the connector and push the tang down to disengage the terminal.
• To install a new wire in the connector, align the lock tang on the terminal with the slot in the con-
nector and push the terminal into the connector until the lock engages the slot. Pull on the end of
the wire enough to be sure the terminal is locked in the connector.
Hinge Lock Type Connectors
Single and multiple contact, plastic hinge lock type connectors are used for making connections to a
mating connector. These connectors are usually located at or near the electrical unit being supplied.
The mating halves of the connector are formed so that they can mate in only one position. When the
connectors are pushed together, the lock tangs on one half engage the mating connector of the other half
to ensure a firm contact.
To separate the connector halves, insert a fine blade screwdriver under the connector locks and pry up
just far enough to disengage the lock hinges while pulling the connector halves apart. Do not pull on the
wires when separating the connector halves or terminals or the wires may be damaged.
Weatherproof, Multiple Contact Type Connectors (Weather-Pak
®
)
Several multiple contact type connectors are used on the coach.
Cavities within each of the multiple circuit connectors can be identified by the letter imprinted just
above the pin or cavity when the connector halves are separated. Cavities within each of the plastic mul-
tiple circuit connectors can be identified by a number which is recessed at the end of each row of cavities
