Install: Open the ytd file while in edit mode, from there you can import or replace any livery texture you want. You need to change the "TG" to the number you want to replace.
Example: a350_sign_TG --> A350_sign_1. Then you replace it with the default a350_sign_1
Not changing the # won't replace anything when added. If not, you'll need to deleted that and redo it again.
Thanks for downloading. CANNOT repost this repaint/texture without my permission!
