Rudy the only modification I've ever done to my car because I wanted to keep it STOCK. I'm here to tell everyone, everything I've ever TRIED to do that would take a normal person 30 mins would take me two hours !! Just me I guess. But installed the Automatic Convertible switch two years ago ...it was the FIRST TIME ....EVER it actually installed without a hitch...in...out 20 mins done. Well done with the install instructions and the product is absolutely flawless. Works like a charm. Appreciate it every time the top goes down/up.
