I was wondering since the PCM can supply the ground for a shift light in my 01 Trans AM do I have to use a 5 volt Led? I could get a 194 bulb socket and a 12 volt LED and put it in a tube inside my center air duct. I was thinking that since the LED draws so little current compared to a bulb that it would be fine? Looking for opinions. I also am leery to run 12 volts to and through the PCM.
thanks Ed
