The how-to for the door handle LEDs? If that is what you are doing, when Colter and I did them in his car we had to steal the power from a purple wire. Connect your new wire that feeds off of that to one end of the resistor. Connect the other end of the resistor to the longer leg of the led. Connect the short leg to a ground.
How many mA do the LEDs consume? It will tell you on the front of the Radio Shack package (I have one in front of me now). That will also be needed to figure out how strong the resistors need to be.
Right now we have this:
9.3 * (1000/mA) = needed resistance
When you find the resistance, divide that into 1000. Times that by 9.3. That will tell you how many ohms of resistance is needed to protect the lamps. A lower number will overrun the lights and they will die quicker. A higher number will make them dimmer.
I hope this helped.
