Need help installing engine sound replacement mod
I recently downloaded a mod to replace the engine sound of an add-on car (Koenigsegg Regera). The instructions that came with this mod are shit, and are very outdated. So I have files that I don't know what to do with and I don't know where to put. I have successfully used another engine sound replacement mod for another car, but that file was completely different and the instructions were clear.
So in this file https://www.gta5-mods.com/vehicles/koenigsegg-regera-sound-mod#comments_tab
there is an .awc and .oac file, also a folder with .wav files. I've looked up multiple videos trying to find an explanation and I feel like I'm getting close, but I still need the help of someone more experienced than me.
