Question 3.9 Swap to 5.2

I have a 2000 CC 4X4 3.9 Auto and just bought a 5.2 to swap. The 5.2 came out of a 94 Cherokee that had an extended warranty and the original motor seized. This motor was replaced with the one I bought and has roughly 40k miles on it. I looked around on this site but everyone is doing a 3.9 to 5.9. As far as I know it will bolt right in but will need some electrical parts to swap. I know I will need the ECM or ECU (not sure which is which) and possibley a radiator, am I missing anything? My tranny is stock but I had it overhauled Feb 06 an had a shift kit put in. I also had to get a new transfer and did my u-joints while I was there. I think it will all handle the power and be o.k. but I need to be sure. Bottom line; what should I look for or need when doing the swap? Any tips or help would be greatly appreciated.

i just finished the same exact swap 3.9 to a 5.2 and it didint go in with out a fight but i got it. you gotta use the axle, drive shaft, ecu from the 5.2 the 3.9 parts wont work and, make sure you keep every last bolt, and put them in labeled bags that makes it so much easier in the end i know it sounds like a pain but trust me its a life saver.
