Mark,
The black Viper in Jason's shop was mine. I got the Quick-Lite (5330) from Autometer and as you saw, I mounted it on the steering column between the tach and speedo. I chose this one because it's so small yet still very visible.
You have to buy the shift light directly from Autometer because they have to recalibrate it for the Viper setup. You also have to buy an RPM module (5310, approx. cost=$65) and the "pills" (approx. cost=$25/pack) that plug into the RPM module to set the appropriate RPM trigger point you desire.
As far as installation is concerned, it was real easy. Like other Autometer shift lights you have to connect 3 wires from the RPM module (+12V, ground, and the tachometer wire out of the PCM module). The RPM module has another cable with a connector that connects directly to the shift light. I mounted the RPM module under the dash using the double sticky tape provided.
Hope that helps!
