The vehicle modifier can either purchase pins for the mating connector and install them on the wires before they are inserted into the connector, thereby avoiding any splicing, or purchase an optional power pigtail for the interface. The power pigtail (P/N 14A411) plugs into the power distribution connector and provides blunt cut wires ready for splicing by the vehicle modifier. See the Police Interceptor Modifier Guide for more details. Rear power point - police The rear power point is a battery access port for police auxiliary equipment mounted in the trunk. It is capable of supplying 80 amps of battery power. The front power distribution box (PDB) contains two 50 amp fuses, which protects the power point. Battery access is via two studs contained in an enclosure, mounted in the trunk, on the right side fender support. The terminal with the red wires is the battery positive, and the terminal with the black wire is the ground. Remove both fuses in the front PDB before removing the cover to the rear power point. Ensure load devices can be turned off, and are switched off when reinserting fuses. WARNING: Under no circumstance should the rear power point cover be removed without first pulling the two fuses in the front power distribution box. Removing cover without pulling fuses could result in an electrical hazard, and result in personal injury. Shut off load devices before inserting fuses. 273 2010 Crown Victoria (cro) Owners Guide, 2nd Printing USA (fus)
