i dont think you understand how this works, youre supposed to modify the trucks themselves
Thank you for the reply. I copied and pasted the sound into the original sound file. Everything else works great, except the jake does not make any sound. It is confusing because there is no error in the output though I checked the script, and I have everything that the creator posted for his sound script and I also have the sound in the sounds folder as well. And to answer your suggestion, it has both <retarder> on the top and the bottom where it is in the script. (I can share the file of the mod I'm using it on if you would like, its a project convert from FS19.)
