I am not familiar with the Jetta in particular but a general answer to the question would be to look to where the lines run. The high pressure line runs to the condenser which is located in front of the radiator, and the low pressure line comes from the evaporator inside the car. Also the high pressure line in later model cars has a smaller diameter port than the low pressure port and requires a adaptor or special hose. If you are in doubt, don't proceed as connecting to the wrong port can cause high pressure to build in the small freon can and can explode. Hope this helps. I am a retired air conditioning contractor who would infrequently work on my own car or those of close friends.
