Is there a difference between the Interactive Control you have linked here and Simple IC I see required for other mods
Yes, they are two separate mods. Interactive Control has way more functionality than SimpleIC and lets me make custom icons for different functions, which is why I choose to use it.
Is it okay to use mods that require each one or do they conflict with each other? Thanks.
They will not conflict, you can have both of them active in your mod folder. The vehicle will just be specific to one of them.
