So I'm hooking up my vleds led switchbacks and got the resistors, but iunno which wire is the "ground" wire that I'm supposed to hook up one side of the resistor. Also, the turn signal socket has 3 wires: red, black, green. Which one do I hook the other side of the resistor to? Please help asap! Whole front end is taken apart and I'm stuck! Have work tomorrow morning at 10...thanks guys in advance!

 

Ground is black or negative.
LED's (diodes) only work one way.
