Only "bigger/different rads" listed at the parts stores is "postal" vehicles. Never seen anything regarding different cams or t-stats. No references in the FSM to "police pkg", iirc. Anyone know if there was a Jeep "Police" code/ID #? Ford has "P71" in the VIN to designate police and Chevy has "9C1" listed on the SPID sticker to identify police. What's Jeep's number/code?

The extended idle switch grounds a wire going to the ECM. The grounded wire is an input to command the idle to approx 1000rpm in park or neutral. If you look at the older xj wiring, it's actually the wire for the power steering pressure switch or the a/c switch on 4cyls. All the xj's have a way to use the extended idle feature.

I have a 99 that was a cruiser for a federal park. I did a little looking around and as far as I can tell there is no true "police" package for the xj, there are just options for the purchaser to put together the vehicle they want, like rubber flooring, rear hard plastic bench seats, extended idle, the oil and trans coolers, trac lock, 10" rear drum brakes...etc.

This is correct based on the research I did.

The first customized Cherokees were unofficial modifications to fleet orders — because fleet buyers of the Cherokee had some problems under severe service with the rear axles, the company substituted Dana 44s from the MJ Jeep comanche metric-ton model. Michael Smith of the Vehicle Development Group was put in charge as Program Manager for the XJ Special Service Vehicle (XJ-SSV); the result was a surprisingly sturdy and capable vehicle, which was almost entirely built using existing XJ and MJ parts.
Former AMC/Jeep and Chrysler engineer Bob Sheaves remembered, “It was an absolute backdoor program — everything done on the Q.T. and at the absolute minimum cost.” He wrote that they used the basic XJ body with the MJ foot operated parking brake and column shifter; the floor-shift for the transfer case had to remain. Tires on early models were the same as the police Diplomat/Gran Fury, Eagle GT 235/70R15 tires; they were put onto the tough stamped steel wheels from the Up-Country option package.
They had to use bucket seats because instead of the Comanche bench “because of the cost of a couple of two-inch spacers for the bench's rearmost track mounts and the cost of recertifying the seat retention in a crash.” The spacers were needed because the floor pan of the truck rose up in front to make room for reinforcements required for the bed attachment; and recertification, which would have cost over $100,000, was required due to the change, as the government needed to know the seats would not be torn out of the floor in an accident. Instead, Jeep engineers had to make do with heavy duty springs and foam in the standard bucket seats with low-line covers.

Front and rear springs and shock absorbers were from the Up-Country package; the front and rear sway bars were heavy duty items from the towing package. The cooling system and power steering pump were from the Laredo towing package with air conditioning, and a transmission cooler was standard. The MJ metric-ton Dana 44 rear axle was retained for years, providing the Cherokees with heavier-duty axles than civilian models, until the late 1990s when Chrysler axles replaced the Dana 44 in both civilian and fleet Jeeps; but, in any case, a new part did not have to be designed, and extra, unique parts did not have to be kept in inventory.
Other than the performance and durability pieces, the Cherokee police package was very basic and bare — an absolute “stripper” model. The results were astounding — the Cherokee easily outperformed other 4x4s in the Michigan State Police tests, even after nine years. Reportedly, according to hearsay, Eagle County ended up retiring their XJs with 300,000 miles on them, while Crown Victorias usually lasted 80-100,000 miles and Caprices were retired at around 125,000. The Cherokee was popular not only with Colorado county police but also with the Border Patrol and even the Marines — when a tough, mobile vehicle was needed for law enforcement or emergencies, the Cherokee was often seen as the best choice.
There were a matchbox-size and larger toy versions made of the Cherokee in the police trims of various departments.

So our SE model with 235/70/15 tires, tranny cooler and locking rear diff is kinda like a highly optioned police XJ? LOL

Well the state police told my grandpa that the motor was not stock in the jeep i got because of the mountain terrain and long open highways so they had to build the motor to keep up with what ever they came across. And even a few of my buddies that are jeepers said that it cant be stock they way it accelerates and top end is.

Kind of hard to believe, case in point, the county sheriffs department has a 1/2 ton GMC pickup, I doubt it's built to take a Z06 let alone a ZR-1. Just because it has the graphics, strobes, siren, there is no reason to think it's anything special, it's "police" not "lemans".

Pictures as requested. Also noticed it has a block heater. It is far from perfect, and I have a long list, but it will be cool when I am done. I got the front end back together from the accident, I think it turned out ok. Things don't quite line up anymore, but I did the best I could. Every single panel is dented in some way, a bummer, but it will keep me from fretting over every little ding! Also, the hood doesn't close all the way because the previous owner put a battery in that is too tall!
