I got a kit with the guage, but I'm not sure what ports to hook to to measure pressure and to add more refrigeratant. I see a port on the dryer/accumulator (silver pill like thing), and then there seems to be a port on a tube coming from the firewall to the condenser. Any tips?

Never mind the directions were weird on the bottle talking like there's two ports and I just needed to add to the port on the dryer/accumulator.... Got cold air coming out now!!! However I may need to flush the system eventually and start from scratch for super cold air.

 

just so you know, the guage you have will only connect to one of the ports, they are diffewrent sizes

 

Thanks got it earlier today.
