This why you got to have experience techs working on the equipment. But as you said IL it does help the next tech down the road if we use only OEM parts. This is very reason I repair the wiring harnesses the way I do. Even when I did bypass surgery on the Z830A, Z950A, and the Z950R I did it in such a way that it could be easily undone if the next tech decides to replace the control modules. Also when installing rocker covers I always transfer the correct model, type(spec), and date code to the new part as I personally hate it when I get one that this is not done.
