The Instrument Panel Cluster (IPC) receives the ignition RUN state input from Central Junction Box (CJB) fuse 21 (10A). The IPC receives the ignition ACC state input from CJB fuse 19 (7.5A). The IPC receives hot at all times B+ voltage from CJB fuse 22 (7.5A). The IPC is grounded through a single hardwired ground circuit.
