ELECTRICAL PARTS GI SENSORS, SWITCHES, AND RELAYS Handle sensors, switches, and relays carefully. Do not drop them or strike them against other objects. kD YELLOW WIRING HARNESS Wiring color codes Two-color wires are indicated by a two-color code sym- bol. The first letter indicates the base color of the wire and the second the color of the stripe. IGI Green 11 R 1 Red I B BR COLOR FUSE Replacement 1. When replacing a fuse, be sure to replace it with one of the specified capacity. If a fuse again fails after it has been replaced, the circuit probably has a short and the wiring should be checked. 2. Be sure the negative battery terminal is disconnected before replacing a main fuse (80A). CODE CODE Black Brown GY L LB LG 3. When replacing a pullout fuse, use the fuse puller sup- plied in the fuse box cover. COLOR 0 P Gray Blue Light Blue Light Green Orange Pink V W Y - Violet White Yellow - Gartner Banana
