My name is Dan.

The Low side service port is between the engine and the firewall back close to where the lines go inside the vehicle from the engine compartment.

Is the cap green in color?
Expert:  Dan replied 5 years ago.
No the green one is the EVAP service port.
The cap should be blue or black on a big silver aluminum pipe.
I am looking for a picture but not having any luck. I will post one if I find one.

That area in blue is completely empty space on my car. There is however a port below the alternator.. to the right of it. This one appears to be coming out of the Engine though.
Expert:  Dan replied 5 years ago.
Look behind the alternator and down.
