Water Pressure Gauge Install Question, F150

[hurricanedavid]

I'm in the middle of installing a Yamaha Pro Series II water pressure gauge to my 2008 F150 and not 100% clear where the engine hook-up port is located.

I think it's located on the PORT side of the engine approximately in the middle and that bolt has an orange gasket. This particular port DOES match the threads of the brass hose adaptor.

Thank you in advance for any information regarding this matter.
