1970 Challenger Rallye Gauge housing

[broughj]

Hi,

There is a hole in the gauge housing near the bottom between the tach and the gauges in my 1970 Challenger rallye setup.  What is supposed to go in that hole?  I have all the wiring hooked up and there is nothing for that hole.

Thanks,

John Brough

It leads to nowhere, it's just an empty hole.
