Reverse Glow Gauges Installation

Whats going on guys. You already know my story as far as my car and the changes that it is going through. The sound system bangs and the car is running well with the exception of a new transmission. I am now ready to install some reverse guages that I have brought but I have the slightest idea about installation. I have heard that the needles need to be removed and everything like that but I was wondering if anybody else knows anything about this and if I could get a walkthrough if possible.

Thanks Again,

Kirk Ross
