This guide will guide you through the process of installing the Grimes Early Autumn mod for the 2025 season.
With Grimes Early Autumn Mod support, the automatic check for lights has been changed to:
ATS: 19:00 (7 PM) - 08:00 (8 AM)
ETS2: 18:00 (6 PM) - 07:00 (7 AM)
The modification can be downloaded in two different ways for both American Truck Simulator and Euro Truck Simulator 2. You can either download it with advertisements for free or download it without advertisements for $1. Both links can be found below.
