Got a 2010 fleet Prostar from a auction, from a big fleet.
In the listing it said it had a engine brake. But I cannot find anything in the cab marked with that, or that 1,2,3, position switch.
Its a 2010 Prostar Premium TA day cab with a ISM 410hp. Ex Soda truck
If anyone has any ideas I would really appreciate it.
Also is adding on a engine brake something very easily done if it doesnt have one.
