lol but really when you open the box you'll look at it and go "oh well this'll be easy" and it is. get your center console off unscrew 6 bolts remove replace rescrew 6 bolts (well this may be tricky cuz your wrench wont fit ut you can do it) replace your center console and go. when you get close to redline it'll buzz when you hear that.. shift and repeat.
