Looking for a thread

Hey everyone, there was a thread about doing a 4.0 swap from the 2.5 on the forum but I have not been able to locate it. It was being done on a white YJ if that rings a bell.
I blew my 2.5 into little pieces and I'm about to do a 4.0 swap and looking for advice on the wiring.

Thanks
 
from what i have heard, the firewalls are different from a 4.0 to a 2.5. i believe that dropping a GM 4.3 is a lot easier. thats what i have heard, it may be incorrect.
