1. (a) All wiring shall conform to current SAE Standard J1292.

2. (b) Circuits

   1. (A) Head, tail, stop (brake) and instrument panel lamps;
   2. (B) Step well lamps shall be actuated when the service door is open;
   3. (C) Dome lamps;
   4. (D) Ignition and emergency door signal;
   5. (E) Turn signal lamps; and

   6. (F) Alternately flashing signal lamps

      3. Any of the above combination circuits may be subdivided into additional independent circuits.

      4. Heaters and defrosters shall be wired on an independent circuit.

      5. Whenever possible, all other electrical functions (such as sanders and electric type windshield wipers) shall be provided with independent and properly protected circuits.

      6. Each body circuit shall be coded by number or letter on a diagram of circuits and shall be attached to the body in a readily accessible location.

   1. Wiring shall be arranged in circuits, as required by SAE Standard J1292, with each circuit protected by a fuse, circuit breaker or electronic protection device. A system of color and number coding shall be used and an appropriate identifying diagram shall be provided to the end user, along with the wiring diagram provided by the chassis manufacturer. The wiring diagrams shall be specific to the bus model supplied and shall include any changes to wiring made by the body manufacturer. Chassis wiring diagrams shall be supplied to the end user by the chassis manufacturer. A system of color and number coding shall be used on buses.

   The follow body interconnecting circuits shall be color coded as noted:

   FUNCTION	COLOR
   Left Rear Directional Lamp	Yellow
   Right Rear Directional Lamp	Dark Green
   Stop Lamps	Red
   Back-up Lamps	Blue
   Tail Lamps	Brown
   Ground	White
   Ignition Feed, Primary Feed	Black

   The color of the cables shall correspond to SAE J1128.

   2. Wiring shall be arranged in at least six (6) regular circuits as follows:

3. (c) The entire electrical system of the body shall be designed for the same voltage as the chassis on which the body is mounted.
4. (d) All wiring shall have an amperage capacity exceeding the design load by at least twenty-five (25) percent. All wiring splices are to be done at an accessible location and noted as splices on the wiring diagram.
5. (e) A body wiring diagram of a size that can easily be read shall be furnished with each bus body or affixed in an area convenient to the electrical accessory control panel.
6. (f) The body power wire shall be attached to a special terminal on the chassis.
7. (g) All wires not enclosed within the body shall be fastened securely at intervals of not more than eighteen (18) inches. All joints shall be soldered or joined by equally effective connectors, which shall be water resistant and corrosion resistant.
8. (h) All wires passing through metal openings shall be protected by a grommet.
