I had installed Shock & Awe engine and rear bag lights 2017. the controller was 1.0. I wanted to use the 2.0 app features. Use the text message option on the web page and they directed me to what i needed; Got it the next day. Many utube videos watched but still not confident to do the install (I ordered front fender lights too) Emailed for advice and got a call back from the senior tech. I am a judge with no mechanical back ground. I DID IT! Looks great! Love the options of brake lights come on entire bike and that I can name my app. Was in Sturgis and had 1,000's of sign in numbers come up on my app. Now with my personal name, easy to find. Very happy. Easy install. Thanks to utubers putting out the very helpful videos.
