Custom Gauge lighting, now in color! Options

First I would like to thank Kent (76-914) for introducing me to Al's wife Shirlee. She was extremely helpful and sold me all of Al's leftovers. Today, I received a huge box filled with led's, cannibalized gauge housings and a very touching note from Shirlee. I also noticed a dismantled tachometer that Al was working on. I was taken back and felt very sad seeing this tach. You could see all the tedious prep work that Al did, but sadly he wasn't able to complete his masterpiece.

I was determined this afternoon to pick-up where Al had left off, in his honor. This thread is broken up in 3 parts. The first part is intended to show everyone how Al achieved his multicolor gauges. The 2nd part is a "how to" to make your gauges into any color you wish. The last part is another "how to" but taking our gauges to a whole new level. As you will see, my design could have a back light color background in any color that you can think of. My uncle has designed a neat little circuit that works in tandem with the RGB color controller. The circuit senses the tach wire, and changes the color of the back-lighting of all gauges to yellow at a certain rpm, then red at another certain rpm. It is fully customizable as you can set the when yellow comes on, as well as the red. There is another input on this circuit board which turns all the gauges to red when triggered. I thought we could use this special input for the low fuel light, or as a fan belt warning for the 911 types. Perhaps the special input could be hacked into a radar detector, many possibilities. Yellow and redline lights again are fully adjustable via a potentiometers, also this circuit will work for any 4-6-8 cylinder engines.

With my last how-to topic, I received many messages from folks that didn't feel comfortable doing this to their own gauges. I have done enough of these in which I feel comfortable. If you're one of these folks, send me a PM and I'll do this conversion for you. For me, it's a 1.5 hour process, but it may take longer for someone that has never done something like this before. I'll try to make this write up detailed as much as possible.

Great! This circuit is very diverse as it was designed for our 4 cylinder or 6 or even a 8 cylinder engines. In addition, this will work with the older 200 volt tach signal, 80's style 12 volt tach signal and the the modern 5 volt tach signal. So, I think we have all cars covered with this design.
