I would not expect the intake manifolds to match up between the 2 motors.
This job would be well beyond me.....matching up the electrical.......add to that.....they made a lot of changes in the 1999 model year......and the intake is even further changed from the 1996-1998.....which I would not expect to match up either.
Unless you REALLY know what you are doing.....you could be creating a lot of issues with this project.
