Wire harness compatibility

I am trying to find info on the two harness LH and RH side rear tunnel behind the seats if they are all the same for different years and interchangeable? They have the fuses and relays and tie into the immobilizer and F1 computer.
Does anyone know if an 01 harness works on the 05?

 

I see part number 182200 gets replaced by 198555. The later part number coming from my car an 05 but the early number an 01 as an example. If the part was superseded is there a difference in the wiring between the years? Does it work on the early cars adapting the later wiring but perhaps doesn't work for the later 05? I want to make sure if I replace this harness with the earlier part number version it will still work properly? I think it should be fine, but I know there are many more knowledgeable people here.
Could I in theory grab bits and pieces of the wiring from different years of the 360's and they be interchangeable?

 

Exactly, its the different systems aspect and going backwards in production date I'm worried about.

 

I have some corrosion on the connectors. I gave a small attempt to clean a few, but it would be worth my time and effort to just replace them if I can. I might just take the chance and give it a try on the earlier part numbers.

 

I tried deoxit on a couple of the problem areas, and that stuff is pretty helpful but mine are just too far gone. It would be easier to build new harnesses from scratch, and I really dont want to do that right now or have the time. I found a good deal on the 2 harnesses RH and LH tunnel with all fuses and relays in seemingly good condition. The ones I picked up are from an 01 so I will report back once I have installed them.
