oh didnt know that it didnt come with the car. i never messed with any of that stuff on my old beretta. if this one lasted 50K miles, then i;m sure the new one will too. id rather not run the risk of breaking anything else(as the car is almost 14 years old) and just leave it as is. if this one goes out in another 50K, well i doubt she’ll still have the car by then haha
