recharging AC

[RayRay]

Its hot as balls where I live and my air conditioning could use some recharging. I already converted to R134a and I already have a few cans of it plus the hose/nozzle to connect to the AC system in the car. The instructions say to connect it to the low pressure side of the AC, I found two nozzles near eachother towards the firewall on the passenger side. <P>My problem is that I don't know which is the high/low pressure one. I have a V6 if that means anything. Can anyone help???

umm, are you sure thats a good idea? Anyway be careful that refrigerant is dangerous...
