Where is A/C Low Pressure Port on ML500
Can't find the Low Pressure port

Thanks very much

ML320
a/c ports
I dont know which is which but the ports on my ml320 a/c are (1) on the pipe inside the engine bay going INTO the cabin, and (2) this port is before the condensor and is around the headlight area. You can see this one from the front of the car when the hood is raised.
