engine swap quesiton?

I know its been said its a pain to swap a 2.5 out for a 4.0 inline six but i want to know can you put a 4.0 out of a 96 cherokee and put it in a 97 wrangler with a 2.5. I also have the tran and transfer case out of the cherokee. I also know new engine mounts. But will all the sensors hook up,will it be a nightmare trying to make it compatable. Or will i have to buy a custom engine harness. Please let me know Thanks

There's a few threads here about that already...if you do a search you'll find them; sorry I don't have the answer for you offhand.

I've also heard that you can put the throttle body from a 4.0 on a 2.5 and it'll make more power.
