I read the "How to Re-charge an Air Conditioner System" The picture and explanation says to hook to high and low pressure ports. Where are the high and low pressure ports and where do I hook the can of coolent up? Do you have a diagram to show these ports?

I strongly advise you not to attempt this. The refrigerant is pressurized and very dangerous. You can also do a lot of damage to the system if not done correctly.
