V8 four wheel drive automatic 88,000 miles.

I have purchased 134a to recharge the Freon in my SUV. The hose connects to the low pressure valve only. The high pressure valve is sitting on top , easily accessible. i cannot find the low pressure valve. Please tell me where it is, or refer me to a diagram that clearly shows where it is located. Thank you for your assistance. It is very hot and need to get cool A/C pumped into my family vehicle.

The low pressure service gauge port valve is located on the suction accumulator/drier.

Thank you Rasmataz for your answer. Can you tell me specifically where on the vehicle? I can find the suction accumulator/drier. For instance, "it is located toward the middle of the vehicle, underneath". I know very little about cars and what the parts look like, so if I know a general location, that would really, really help. Thanks again.

It is here on the accumulator which is located at the firewall near the rear of the engine compartment.
