Where do you plug in to recharge ac in 1987 rx7?

To recharge the air conditioning system in a 1987 Mazda RX-7, you would typically locate the low-pressure service port, which is usually found on the larger diameter line between the compressor and the evaporator. This port is typically capped with a plastic or metal cap and is where you attach the refrigerant can or service gauge. Ensure the engine is running and the A/C is set to the maximum cool setting while recharging. Always check the vehicle's service manual for specific details and safety precautions.
