Yes. Look on the rear axle for a tag. It will be bolted to the rear cover. If it has the numbers (example) 3 L 27, or any combination of numbers with a L as a second digit it should be a locking type differential. These are fairly uncommon in non Police vehicles.
The locking differential can be found on non-Police Crown Victoria and Grand Marquis models which came equipped with the optional trailer-towing package.
Also, if the door sticker is still on the drivers door, it should have something that says "Axle" with some numbers below it. you can see which differential you have with that incase the above mentioned tag is missing.
It was an option.
Not normally, but it was an option.

Not usually. Only if ordered from the factory. But, it does have a anti-slip in the transmission.
That will depend on which differential you have. There is more than one. Find the metal tag located under one of the differential cover bolts on the rear end housing.
They need both a positive connection and a negative connection to function.

You need to remove the fuse for it, for that you'll need a manual for that model and year. The above answer is incorrect, sure you could do that but!!!! Check in the glove box to see if there is a round push button switch. If there is and it wasnt removed- this button will disable the traction control. To verify that it is off there will be a light that says traction control that will light up on the instrument panel. It will reset back to ON everytime the car is shut off. This is on a 1998 p71 Crown victoria, an LX Vic should be the same.
