Just installed my new Raptor Performance shift light and it is sweet. It does NOT require a tach adapter and all the wiring is done in the interior of the car. It is super bright and even in direct sunlight it is very easy to see. A very cool mod. I got mine from Butt Ugly Customs for $85 SHIPPED. Cheapest place on the internet, and it got to me in less than a week. Here are some pictures and a VIDEO .
