Install was pretty easy (like any other gauge install). I got the premium electric boost gauge with peak hold.
I have to say, i'm impressed with fitment and how it looks!!
Here is my youtube video of guage light transition.. Daytime it will light up white and night it will match the amber light. FYI: My cluster amber is bit lighter as I have the white face NS conversion.. I believe if you had stock cluster, it will really match the light..
