Low Side Port on '99 F-150 w/5.4

After 10 years, my AC is cool, but not as cold as it once was . . . (also happens to us humans as well ). I've bought a AC freon recharge kit with a guage and hose. Now exactly where is the low side port to add freon to my '99 F-150 w/5.4 engine?

Thanks!

You have two, one port in the front of the engine compartment near the radiator. And the second closest to your firewall in the rear of your engine compartment.

PS I'd wear gloves

You should charge your system through the Schroeder valve on the accumulator.
