Copy the .lua file into the scripts folder in your Mafia III directory (Default for steam is C:\Program Files\Steam\steamapps\common\Mafia III\scripts).
Remove the .lua file from your scripts folder.
Default keys are:
“P”: Turns engine off. To turn it back on tap “W”
“I”: Turns headlights on.
“O”: Turns headlights off.
Simply edit the .lua with a text editor and change the keys to your fitting.
I am still looking into adding more features such as opening/closing the trunk/hood and doors.
