Gentlemen,
Needing some help and advice on a little wiring project. Below are the gauges i have decided to go with for my '69 Signet.
These gauges are designed so that you can run either red or white LED back lighting.
As you can see, you wire them up to power the white LED or red LED as you choose, simple.
My idea is to build a harness for the tach so that it is normally back lit by the white LED, but at a certain RPM, power cuts out to the white LED, and the red LED is energized. Basically creating a shift light thats impossible to ignore. I know this can be done, but I'm just an old 11Bravo, so don't know where to start.
Even if there is some type of complete off the shelf module available to accomplish this, I would rather build it myself for the satisfaction and entertainment.
All legitimate responses and smart a$$ comments welcome
thanks in advance
