The instrument cluster is a hybrid electronic cluster (HEC), which uses both hardwired circuitry and the standard corporate protocol (SCP) communication network to transmit and receive information. The Mustang instrument cluster backlighting has illumination bulbs that are installed separately from the instrument cluster. The Cobra instrument cluster has a laminated, electroluminescent applique to backlight the cluster . The electroluminescent applique and instrument cluster must be installed as an assembly.
