yes. The wiring harness needs to match what the PCM and body wiring harness is expecting.
Do you realize that this will be removing a PI motor to replace it with a non-PI motor?
It seems that you will get a better result if you were to use a Romeo out of a 2003+ model year.
I didn’t remove anything the car came as is , I purchased it as a roller , I was only able to find a non pi engine in my area so went that route to do a pi swap later on but needed help figuring out the harness problem
So I have to purchase the regular 00-04 harness ? I didn’t have one due to fact car came as a shell only had the body harness that’s on the car
You can either find an 00 harness or splice the hell out of both harnesses to make the 96 one work. Given that the 00 PCM has more wires to it than the 96, you'd likely have to add a few pieces as well.
Get the 00 harness and save yourself the work in my opinion.

From Experience.
I removed a 95 3.8 and replaced it with a 02 3.8. I tore down both wire harness' and then made a custom out of the 2 so I could put it back inside the 95 and still use the same computer I have always had.
If there is a kit that makes this easier, you should consider using it. If there is not a kit. The first thing you need to do is get a manual for both engines. In my case its the same manual. That way you can check out all of the wiring and make things work correctly in the right pin so its compatible with the computer that you will end up using. If you do tear into both harnesses like I did. The one you need to use will be the one that is coming out of the car that you are putting the new engine into. This is because the pins at the block on the firewall will match up correctly and you only will have to worry about what is from that point to the end of the pigtail in making the wires functional. In my case I needed to use sensors and things from the 95 on the 02 so the computer would stay happy. In that I needed to use pigtails off the 95 also to make the senor happy.
Its a matter of choice, in my case the custom route was the only option.
