Just picked up a 2010 Crown Vic, & looking to install a few radios. On my 2005 Impala PPV, there were wires under the carpet by the front passenger's feet. This included 13.8 volts +, -, & ign trigger wiring, so I did not need to go to the battery. These wires were installed by Kerr Industries, the GM factory upfitter along with the other police wiring. So before I rip the Ford apart, are there similar wires in the Crown Vic for 2-way radios?
It's been a few years, so bear with me here.
Regardless of the wiring options ordered, a 2010 model should have the following as standard:
Under the glove box, pass side kick panel area, there should be a multi pin gray connector. It's something like a 14 pin (maybe?). You'll see a bunch of smaller wires and some larger #10/12 stuff. Those are hots and ignition. I believe the pink, or pink with white stripe is your ignition. There is also a large red and black in the same area that terminate to a black 2 pin connector. This is the "light bar" power connector. I think it's fused a 50 amps or there about. Depending on how hacked the wiring is, sometimes the connectors will be completely cut off, but the wiring should be there somewhere..
In the trunk there should be a 100 amp power stud on the pass side area. Fold back the liner just ahead of the tail light and you should see it. It should have a black snap on cover if it's still there and not missing. This is a hot all the time stud.
The car may have more, but that's the bare bones it should have. Again, I'm going off memory here so I hope this helps.
