I run sports car rallies in my Arntz Cobra and need lots of electronics. You can see most of it in this old picture:
The K40 police scanner display is hidden behind the steering wheel on the left side. Molded into the top of the steering column is a very bright
oil pressure warning LED. On the right side of the steering wheel is the TSD computer driver's display. Below that is the Monaco Systems countdown timer. Next is the Alfa Elite Navigator's module. To the right is our reader board for the rally instructions. It is internally lit with LED's and has an external light also. The clear dome under the mirror is a voltage status indicator, green, yellow, and VERY BRIGHT red. The Valentine 1 is not shown, I put it under the seat when I park. After this picture was taken, I bought a Garmin GPS and now that takes up some room on top of the dash. Peeking out from under the passenger side foot box is my old MSD 6AL. That has been replaced with a Ford EDIS distributorless system. You can see that in this link:
Ugly engine bay
We don't take these rallies very seriously. :^)
