as far as your flashers are concerned they are both 2 prong, i go with the cheap silver one in the top placement (this is hazards) and a heavy duty clear in the bottom placement (this is for turn signals)...secondly if you dont want to get your electric fan wired so it come on with ignition which is prolly your best bet you can add water wetter to the radiator coolant and also try and make sure all the air is out of the system. good luck and keep us updated....ps the fashers are plug and play pull oneand pushth new one into its spot.
