This MOD allows us to hide the horn addons inside the truck, without exposing to outside view. The horn plays as usual when we press the horn button.
WILL WORK ON ETS2 1.43.x
It only supports to the addons configured with l_horn and r_horn accessory slots.
If you are trying to place an addon and it doesn’t listed out, you can manually edit the sii file in the horn mod scs file by adding support to “l_horn” or “r_horn”
