if you are asking about this:
https://flightsim-studio.com/727 which I believe is for FS2020/24, then best to ask/post in the appropriate forum i.e. MSFS2020/2024 forums and not the FS2002/2004 forum, but you are better off seeking assistance @ avsim MSFS2020/24 forum frequented by the many interested, knowledgeable and experienced in civil aviation [SOH is largely military aviation], if not also consulting the extensive online documentation
https://docs.flightsim-studio.com/boeing-727 and if all that proves to be in vain, then best to post your query at PPRuNE
