Wiring harness question

I have a 2004 3 with the 2.3 engine that had been "modified" by a previous owner, by modified I mean they had cut the wiring to the neutral safety switch/inhibitor switch on the transmission and hard wired it. While this worked for a while it is causing problems again and I want to get the wiring back to normal. My question is, I found a wiring harness from a 2.0 engine and want to know if it will work or if I definitely need one specific to the 2.3. Since it is the wiring harness, not the switch itself, I just don't know if there is a difference.
