On most vehicles that came with 134, the charge fitting will only go on the low side. If you have a manual, it will tell you, but you can also figure it out by following hoses. High side is from compressor to condensor (in grill on most cars) to drier to expansion valve. Low side is after evaporator (buried in car dash) before returning to compressor. A quick google search will probably turn up a basic auto AC diagram showing the basic components of auto AC systems I mentioned above.
