I just recharged mine. If you have a rear air conditioner the low pressure connection is going to be righ over the top of the compressor facing to wards the front of the vehicle. Stand in front of the engine and look at the plumming for the AC. the ports are covered by black caps, there are three of them. You should unscrew to access the port. Be very careful when recharging the air coditioner as the engine has to be running. Good luck, Tizo I just recharged mine.
