you need the evaporator- it goes in the blower motor housing/ heater core housing. You also need an expansion valve, the suction and discharge lines going to and from compressor to condensor and evaporator. Also need the ac wiring harness- including the dash switch, the compressor leads, and the pressure switch lead. Also you need the filter/dryer unit. Mazdas where originally R-12, you will probably want to go ahead and convert it to 134a- so you will need the converion kit too. You will also need new rubber orings and seals.
