Help with LED wiring.
(OP)
I am building a simple circuit. All it does is that when I flip on a switch it throws a 4.3 volt diode into the circuit. I am trying to figure out how to hook in an LED so that when I turn on the switch the LED turns on. The voltage that comes into the circuit comes from my MAP sensor so it is not constant.

RE: Help with LED wiring.
Do you have access to constant voltage from elsewhere? Even the 5V supply to the MAP sensor(assuming it has one) would help you out. If all you want is for the LED to come on with the switch, and you have a 5V supply, and 4.3V LED, it would be pretty easy.
