It will not. The 2001 and 2001 have distributorless ignition. Every Jeep before 2000 has a distributor. You need a 2000 or 2001 XJ ECU.

Here's something I found somewhat useful:

Hey - that's me! Sounds like you figured it out but posting the updated article for anyone else that comes across this:
https://craftsmancollab.com/p0201-jeep-injector-circuit-faulty-ecu/

I went through the mosfet driver repair as mentioned above and in the old article, but have since switched to a mopar refurbished ECU after a faulty connector shorted the driver again.
Lots of details in the article linked but overall make sure wiring is 100% unproblematic before replacing an ECU.
