Technical 500l Trekking Turbo gas AC recharge low pressure port location

[brucesp]

I have a 2014 500l Trekking turbo gas model. I've located the high pressure port but can't locate the low pressure port. This is NOT the diesel. I found those threads but can't find one for the gas model. Any help would be appreciated.

Have you removed the air box from the engine these can often hide the ports
