416H main harness differences?

[Anthony Wendover 124]

I have a question about the Main harness on the 416H. I am looking at parts and i see there are  5 different part numbers for the harness. What is the difference between them? There seems to be no description. The part numbers are as follows. Any help trying to see why so many numbers for the part and what they mean would be cool. Thank you!
