Police relay outputs and control circuit connections are terminated in 3 connectors at the right front of the equipment mounting platform. Battery power is supplied through two fusible links, one 100 amp and one 60 amp, to three circuit breakers and two control relays located in the trunk relay center. A 50 amp circuit breaker feeds power directly from the fusible links through a 10 gauge (6.0 mm) wire. Two 30 amp circuit breakers

supply power from the fusible links through the contacts of the control relays to 12 gauge (3.0 mm) wires. Each relay is operated by an 18 gauge (1.0 mm) brown or blue/ yellow control lead terminated in the 6 cavity connector. A 8 gauge (8.0 mm) ground lead is provided in the 2 cavity connector. The total current available through the 12 volt power supply is 110 amps (1320 watts).

Ignition controlled power and signal circuits are also included in the 6 cavity and 16 cavity upfit connectors.
• A violet/yellow 10 amp fused circuit, HOT in ACCESSORY/RUN; fuse EF131 is in the end of the instrument panel. • A violet/gray 10 amp fused circuit, HOT in START/RUN; fuse EF26 is in the engine compartment fuse block. This circuit is also located at the RH side of the trunk in a white connector above the rear auxiliary power junction block (see page 13). Total power available for the combined front and rear circuits is 60 watts. • A yellow Park signal from the Body Control Module (BCM). This circuit provides switched 12 volt power when the transmission is not in PARK (P) and the engine is running. The electrical load attached must not exceed 0.5 amps (one relay coil). • A white/black vehicle speed signal (4000 pulses per mile) from the ABS module. Connect only a high impedance load. • A white/violet Surveillance Mode circuit. When grounded, all automatic lighting is suppressed and the radio display is OFF.

When the vehicle lighting system is in the Automatic Mode (Headlamp switch in the AUTO position) and night time conditions exist, the exterior lighting will automatically come ON. In day time conditions, the Daytime Running Lamps (DRL) will be ON. Surveillance Mode is a standard feature in the Caprice Police vehicle. The Surveillance Mode circuit is terminated in cavity 1 of the 16 cavity upfitter connector P277, located at the passenger side front of the equipment mounting platform. When Surveillance Mode is activated by applying a ground to the White/Violet wire in cavity 1, all automatic lighting functions are suppressed. All manually operated lighting controls remain functional, e. g., exterior lamps, turn/stop. If RPO VVS, DRL and AUTO HEADLAMPS Disabled is present, exterior light is manually controlled; all other listed items are suppressed when Surveillance Mode is activated.
An in-line connector in the forward lamp harness permits installation of a compatible flasher module for the exterior lamps Emergency Flashing System. The in-line flasher module connector is located at the RH end of the upper radiator support and includes two wiring circuits to the front compartment foot well. A green wire is intended for customer connection to switched 12 volt power to activate the flasher module. A second blue/green wire permits optional separate control of the headlamp flashing and rear lamps flashing. Separate control of the rear lamps flashing requires opening the blue/green control circuit at the in-line connector terminal P181-F and application of switched vehicle ground to the control wire in the forward compartment, P27716. Power to the blue/green wire must be OFF to flash rear lamps only.
Warning: BCM will be damaged if 12V power is connected to the dark-blue/ yellow wire.
• Radio Display is OFF (If the radio is ON, the audio remains on in the Surveillance Mode). • Instrument Cluster is OFF (PRNDL remains barely discernable per FMVSS 101). • Low Beam Headlamps are OFF; DRL are OFF during daytime. • High Beam Headlamps are OFF, Flash-to-Pass remains functional. • Tail Lamps are OFF (Stop Lamps and Turn Signals remain functional) . • License Lamps are OFF. • Dome Lamps are disabled (inoperative at the lamp switches) and remain off when a door is opened. All interior lighting is OFF, e. g., controls, HVAC, glove box, trunk. • Auxiliary Dome Lamp (RPO 6C7) is functional but locally switched at the lamp base. • Remote lock/unlock audible/visual functions are OFF; horn chirp OFF when a door is open with remote lock requested. NOTE: Wiring diagrams for these options are shown in the Police Package owner’s manual supplement (shipped in glove box).

Two 20-gauge (0.5 mm2) wires are connected to an in-line connector in the horn circuit of the instrument panel harness under the instrument panel. The end of this harness extension is terminated with an in-line connector in a 60-inch coil under the instrument panel. Connection to customer switching permits operation of the horn or siren with the horn button.
The SEO 6J3 wiring provision circuits are terminated in the 16 cavity connector at the front of the equipment mounting platform on the passenger side. The wiring circuits are routed from the passenger compartment to a 2 foot (30 cm) coil secured in the area behind the grille. There are four 16 gauge (1.5 mm) wires for connecting to the grille lights and siren speaker.
