Hi,
I'm writing this post in case someone has to reprogram the PATS system (keys); this should work on any 99-04 mustangs.
This was tested and worked successfully on a 2001 Mustang (the car came with one key even tho it appeared that two were programmed).

You would have to download FORScan (see download link).
Buy a $10 licence for a year (minimum) and an OHP Elmconfig ELM327 OBD2 USB adapter ($29.99).
After you have these you are ready to program your PATS.
If you have only one key that is already programmed, you would need to buy a second OEM Ford key to be able to program it (Strattec key #597602 - can find them on Amazon and eBay between $10-$20). ACE Hardware will cut your new key [$3].
FORScan will let you program the PATS only with a license.
Installing and getting connected to the car should be straight forward.
Once you have all (the new key/s has to be cut before programming - you would be required to turn on/off the ignition with each key)

Within the PATS function of FORScan you will have to choose option [Erase and Program Keys].
Wait about 10-12 minutes until the software will tell you how to actually program the keys.

Watch this youtube video posted by someone, it will help you with the steps.

Not tested yet, but FORScan should be able to reprogram PATS if you swap/change your cluster assembly [99-04].
FORScan team told me that once you are done with the PATS programming of your new cluster, you will have to go back to the same function select [Module Initialization].
Like I said, I did not test this function yet (for instrumet cluster swap/change).
I successfully reprogrammed two keys (one old and one new) for a 2001 Mustang.

I'm glad to see examples of people taking advantage of the very cost effective FORScan software. Especially real world success stories.

ForScan ODB2 scanner w ELM327 USB

I'm a big believer that adding an ODB2 scanner to the trouble shooting "tool box" can forever change the methods used to "fix" your car.

I think FORScan will be a very power-full tool in the future [even now it is].
