90 integra ac low side port location

[muk5]

Hi can anyone point me to the location of the low side ac port on my 90 integra?
I can only see one port which is hooked up to the line between the compressor and the firewall.
so i cannot figure where the other port is .Any help would greatly be appreciated.
Thks

I think the port you are talking about is the line that goes behind the bumper and goes to the dryer. The silver cylinder that's by the wiper reservoir.

i finally figure where it is and the line with the port is just below the fat lines that goes to the firewall
and it is a smaller copper like and the port is smaller . i hope that will help others cause i searched
all over the net and a lot of people asking the same questions but it appeared nobody wanted to answer .
