question about ac

i have a 90 wrangler with the 4.2 engine. has stock air conditioning that was supposedly converted over to 134a recently. However, I cannot find the low side port anywhere. I have searched both lines coming off the compressor. Any pics available that might show this exact car and how it's supposed to be set up?

No such thing as stock AC. Yj AC was a dealer add on only.

Go to for AC layout, or call them they are very helpful.

On my A/C you add the refrigerant to the back of the compressor. You have to screw in the valve to allow the refrigerant to enter.


I have a jeep...and it is modified...I win.
