ECU got wet, what year ECUs will work for it?

So something isn't right with my ECU, it hasn't idled correctly ever since let the GF pressure wash the engine bay after a race.. (Worst mistake of my life) and ever since then it hasn't run right. I have replaced everything when it comes to ignition system and fuel delivery. Flushed fuel lines, drained fuel cell, replaced all injectors, replaced everything from spark plugs to all the sensors on the throttle body, and cleaned throttle body. I am at a loss as to what else it could be. Its like its choking when its idling. when you get on the grass it seems to run a little better but it is in no way drivable right now.

So, we have decided to replace the ECU. Its the only other thing we think it could be. I noticed today that it's almost like someone stuck a second sticker on it like they were trying to cover up the original? Or maybe the factory did this. Here are pictures of said Jeep and ECU before and after pulling the overlapping sicker off.

So my question is, what ECUs will work with this Jeep, and does it have to be from this exact year and model? (04 Rubi) or can it be from any TJ as long as it's the newer style gauge cluster (02+ I think?)

Thanks guys!
