12v lighting - Dimmer harness, the solid green wire.
ground - Chassis or the white with black stripe wire on the dimmer harness.
12v ignition - Defroster harness, the solid yellow wire. (Ugh, I can't remember if this line is run through the headlight switch or not. If your car is pre89 use the Black wire with a red stripe that runs to the cruise control switch. Otherwise, test the yellow one to see if there's power there when the lights are off.)
