Working with refrigerant is extremely dangerous. It can freeze eyeballs and cause frostbite. Most professionals wear a face shield over safety glasses, and gloves. If you're prepared to do that, there's only two fittings on the system and they're different sizes. The hose that came with the recharge kit will only fit the low-pressure port. It will be on the compressor or hose between the firewall and compressor.
The compressor must be running to draw the refrigerant in. If it doesn't start up, you may need to bypass the low-pressure cutout switch. If the can isn't empty within two minutes, place it upright in a pot of hot water.
