WHat year 4.0 did they stop incorperating the EGR valve and tube and go to an IAC versus the idle step motor?

Wow, that's like a trivia question. And the reason for your asking? My guess would be when CC started putting in the H.O. version of the 4.0L ....1996?????

The reason for the question is I have an 4.0 HO and I want to put it into my 89. Thought that I could just use the block and head then bolt all the other "89" intake and such to it. I could just find and harness and ECM to replace the "89" harness and ECM.
