Normal Operation
With the ignition switch in the START/RUN position, the instrument cluster receives power from the central junction box (CJB) fuse 4 (5A), circuit 15-GG1 (GN/BU) and 17 (5A), circuit 15-JA14 (GN/BK). With the ignition switch in the RUN/ACC position, power is received from the CJB fuse 13 (5A), circuit 75-GG15 (YE/GN). With the ignition switch in the OFF position, the instrument cluster receives its keep-alive power from the CJB fuse 20 (10A), circuit 29-GG11 (OG/BU). The instrument cluster grounding is accomplished through circuits 91-GG11 (BK/BU), and 31-AL11 (BK).
