One approach is to remove all sensors, manifolds, everything from the 98 and transfer to the 05. The harness should then plug in, but The 05 is a different series than the 98, so there may be some (or many differences between the two). So strip the 05 down to the longblock and put it back together with the 98 manifolds, sensors, alt. AC compressor, fuel rail, EGR, exhaust etc.
Not trying to be vauge on this issue, but generally, when you swap engines, they are generally interchangeable for 1-2 or 2-3 years, in other words, you could probably swap a 99-01 with much fewer problems, but when you skip 7 years you are pretty much in experimental mode.
Also you generally want to swap a transverse engine into a transverse application, not a longitudinal engine into a transverse.
