Someone has to know

Hello fellow gear head,
I need to have a question answered. I have a 98 F 1504x4 4.2L and i am looking to do a motor swap. The new motor is a 4.2L also but out of a 01 F 150. Everything appears to be the same except for the intake runner control box on the 98 it appears to have a vacuum powered adjuster where the 01 has a electronic box to move the runners. So if you can tell me this. Can I just plug in the new motor or do I have to change the adjuster and the motor wiring harness???
any help would mean allot.
thanks
James
