On any Jeep/Chrysler up to 1995, all you have to do is put your key into the ignition, DO NOT START, turn it to the on, then off, then on, then off, then back to the on. Very soon you will see the check engine light flash. The first set of 2 flashes should be a "Flash-short pause-Flash-Flash-Long Pause, this is a code 12. Code 12 is very normal and should be there. Watch for other flashes after this one. The finale flashes will be a series of 5 flashes-short pause-5 flashes, which is a code 55 that means all codes have been retrieved. Many people have trouble understanding how to read the codes, if you just write down ALL of the flashes and separate the first 2 flashing numbers and the last 2 flashing numbers then you should be able to figure out what the other flashing numbers are. From there you can find out what the codes mean by going to many places on the internet, this is one of them. http://allpar.com/fix/80s-codes.HTML or you can even find them at autozone.com I hope this helps you out.

I am not sure what you mean by reconfigured. If the cruise is not working the first things to check are the vacuum supply to the servo and to check the pcm for trouble codes.
Assuming the check engine light is illuminated, have the Diagnostic Trouble Codes (DTC) read. If in fact you have a bad cat, the codes will help lead you to the faulty cat. Your local auto parts store can help you with that at no cost.
