Is your system completely empty? Or are you just needing a boost to increase cooling? I think all systems have 2 connectors. A low and a high pressure. You need to locate the low pressure. That is what the filler hose is designed to fit.
On the other hand, if you have the old freon connectors you need to get a changeover kit and make sure your system is completely empty of R12 before proceeding to install the R34 with new connectors.
Although you can still buy the older freon from places like ebay. The older hoses too.
