How do I locate the Low Side service port in the A/C system of a 1996 Volkswagon Jetta?

I'm trying to recharge my A/C/ systems and need to locate the low side service port of the A/C system in my 1996 Volkswagon Jetta Trek. All of the third party repair manuals (Haynes) sink and show no photos... The recharge hose, such as that with the Quest r134a recharge kit, are only supposed to fit the low side.How do I locate the Low Side service port in the A/C system of a 1996 Volkswagon Jetta?
Follow the tubes from the ac compressor, you will find the service valve most likely next to the condenser (in front of the radiator) with a plastic cap with a letter L on it.How do I locate the Low Side service port in the A/C system of a 1996 Volkswagon Jetta?

Passenger side, almost against the firewall, about half way down. Both ports are found here.
look at the firewall on the passenger side for 2 aluman. pipes

about 1/2 inch in diam. you will see a plastic cap that should be blue in color that will unscrew and reveal the low side. this fitting works like a quick-coupler used in garages that have air tools. you pull the ring and push on and it locks, pull the ring back and it pops off the fitting. the high side of your system is in the front of your vw, so stay away from there. make sure that your electric fan also kicks on.with the a/c on
