I'd like to put a digital LCD trans temp gauge in one of the switch blanks in my 'other' vehicle.
I can fab & solder but don't know electronic circuits. What parts do I need? An RGB LED to color match the dash lights would be cool.

And while I have your attention
I have a 4 channel car amp that 1 channel worked intermediately then finally quit. What is the likely failed component and how do I check it?

Thanks
