This is the normal fire engine wich is from the fire brigade i uploaded.
Please keep in mind you have to subscribe to the Siren mod and place the modified buzzer and logic it up yourself because the game doesent allow modded vehicles to be uploaded.
When placing the modded buzzer from the siren mod theres a hole in the roof where its supposed to be. The button for it is inbetween the two front seats.
Thanks to "suspicious_cat" for letting me use his truck as a blueprint.
