I'm not 100% sure that the fairmont(High series BA's)range has police mode configuration in the instrument cluster module(most police vehicles are Low series vehicles). Won't hurt to ask though. One point i must make though, When the police enable thier speedo to a digital reading they then calibrate them to make sure they are acurate. Most police BA's i've seen have a decal on the windscreen that states,"For speed related offences use the digital readout", or something to that effect.
