VSS Interface
Crown Victoria 2002 and up
1. Connect the universal VSS cable to the radar’s power/signal cable.
Locate the vehicle VSS wire (gray with black tracer). The VSS may be available at multiple locations in the
vehicle. If your vehicle is equipped with the optional Front Power Access connector (below left picture) the VSS
wire is located at pin 2 of this connector. The VSS signal is also available at either C175 on the power train
control module (PCM) or at C122 on the speed control actuator in the vehicle’s engine compartment (below right
picture). The VSS wire may also be accessible in the passenger floor kick panel or behind the glove compartment.
Note: A connector with blunt cut wires for accessing the VSS and
other power wires from this connector may be purchased from
your local Ford dealership. Refer to the Ford Crown Victoria
Modifiers Guide available at www.fleet.ford.com for part number
and wiring information.
2. Route the blunt cut end of the universal VSS cable to where you are accessing the vehicle VSS signal.
3. Using a scotch-lock t-tap and male quick-slide terminal, connect the red wire of the VSS cable to the vehicle
VSS wire.
4. Connect the black wire of the VSS cable to a vehicle chassis ground.
5. Secure all cables and proceed to accuracy test.
