Location of AC ports High and Low

Hi guys, my own van is a '98 Econoline but part of the fleet of where I work is replete with Ford Transit vans. In our shop we have a Commercial Robinair 34788 that allows for vacuum of the system oil removal, leak detection and replenishment of oil and refrigerant. I've received some training but locating the high/low ports is getting to be troublesome. The low port is out in the open on all of our Transits but it seems that the high port is always hidden. I've been scouring videos to find this bugger and it appears to be somewhere below the PDB. Can anyone help me with a photo or video link showing this port? Thanks and a lift of the lynch lid for your responses.
Gus

I found that on 2017 they're both near the PDB on located higher than the other on opposing sides, on the 2022 one is on the extreme right side (passenger) and the other is high in the center of the engine bay. Our other vans are on the road right now so lacking further information I'll search them as they arrive back now that I figured out where to start. Now onto the Ford Grech Tupperware buses.
Okay this is easier than I thought. The caps for the ports on these Fords are the same in the years of vans in our shop so as long as I can find the caps, I'm in good shape.

One of our newer drivers was struggling with the Trans Air on the back of our E450SD but it was just that she hadn't been shown the Trans Air control panel.
Now all that's left for me to figure out are the roof mounted AC units.
