1999 Saab 9-5 4 cyl Automatic 115000 miles

I just want to confirm that the Saab 9-5 takes regular R134A for the AC (given these cars are so special) and that the green cap on the left side of the car is in fact the low end that it should be hooked up to for a refill. Crazy that it's a plastic part...so easy to destroy. I just can't see paying someone to do something as simple as that. I did it with no problem on my other car, but this darn thing doesn't specifically confirm that that is the right spot. Any help greatly appreciated. Thanks
