Install: Could be really easy, but it was not. I could get the piece connecting to the pedal to click, but I could not get the piece connecting to the other cable to click. I even ordered a replacement for this, and still had the same issue. So I ended up securing it with black tape, and then a zip tie. But to be honest, all you need is the zip tie to make sure it stays connected in place. Other than these minor install hiccups (which I don't see others talking about, so could just be me), it's a great product for my Tacoma, it does what it says. Only used it for a day, but loved it right away, and also love the bluetooth for easy mode switching. Also, the bluetooth allows you to install it anywhere, so I tucked it hidden under my dashboard, and only use the bluetooth. You can always disable it when taking it in for maintenance.
