Engine replacement 01 into a 99 TJ both 4.0

[99jeep]

Will an 01 tj 4.0 drop into a 99 tj for replacement? Will computer need to be changed to or is it a simple engine swap? Thanks

Mark @Wranglerfix may know-

For sure do your homework. Engine swaps are for sure harder than years back.

Doesn't the 01 have a coil rail vs a distributor for the 99?
